 # Stagehand Project
 
-This is a project that uses Stagehand, which amplifies Playwright with `act`, `extract`, and `observe` added to the Page class.
+This is a project that uses Stagehand V3, a browser automation framework with AI-powered `act`, `extract`, `observe`, and `agent` methods.
 
-`Stagehand` is a class that provides config, a `StagehandPage` object via `stagehand.page`, and a `StagehandContext` object via `stagehand.context`.
+The main class can be imported as `Stagehand` from `@browserbasehq/stagehand`.
 
-`Page` is a class that extends the Playwright `Page` class and adds `act`, `extract`, and `observe` methods.
-`Context` is a class that extends the Playwright `BrowserContext` class.
+**Key Classes:**
 
-Use the following rules to write code for this project.
+- `Stagehand`: Main orchestrator class providing `act`, `extract`, `observe`, and `agent` methods
+- `context`: A `V3Context` object that manages browser contexts and pages
+- `page`: Individual page objects accessed via `stagehand.context.pages()[i]` or created with `stagehand.context.newPage()`
 
-- To take an action on the page like "click the sign in button", use Stagehand `act` like this:
+## Initialize
 
 ```typescript
-await page.act("Click the sign in button");
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL", // or "BROWSERBASE"
+  verbose: 2, // 0, 1, or 2
+  model: "openai/gpt-4.1-mini", // or any supported model
+});
+
+await stagehand.init();
+
+// Access the browser context and pages
+const page = stagehand.context.pages()[0];
+const context = stagehand.context;
+
+// Create new pages if needed
+const page2 = await stagehand.context.newPage();
 ```
 
-- To plan an instruction before taking an action, use Stagehand `observe` to get the action to execute.
+## Act
+
+Actions are called on the `stagehand` instance (not the page). Use atomic, specific instructions:
 
 ```typescript
-const [action] = await page.observe("Click the sign in button");
+// Act on the current active page
+await stagehand.act("click the sign in button");
+
+// Act on a specific page (when you need to target a page that isn't currently active)
+await stagehand.act("click the sign in button", { page: page2 });
 ```
 
-- The result of `observe` is an array of `ObserveResult` objects that can directly be used as params for `act` like this:
+**Important:** Act instructions should be atomic and specific:
 
-  ```typescript
-  const [action] = await page.observe("Click the sign in button");
-  await page.act(action);
-  ```
+- ✅ Good: "Click the sign in button" or "Type 'hello' into the search input"
+- ❌ Bad: "Order me pizza" or "Type in the search bar and hit enter" (multi-step)
 
-- When writing code that needs to extract data from the page, use Stagehand `extract`. Explicitly pass the following params by default:
+### Observe + Act Pattern (Recommended)
+
+Cache the results of `observe` to avoid unexpected DOM changes:
+
+```typescript
+const instruction = "Click the sign in button";
+
+// Get candidate actions
+const actions = await stagehand.observe(instruction);
+
+// Execute the first action
+await stagehand.act(actions[0]);
+```
+
+To target a specific page:
 
 ```typescript
-const { someValue } = await page.extract({
-  instruction: the instruction to execute,
-  schema: z.object({
-    someValue: z.string(),
-  }), // The schema to extract
+const actions = await stagehand.observe("select blue as the favorite color", {
+  page: page2,
 });
+await stagehand.act(actions[0], { page: page2 });
 ```
 
-## Initialize
+## Extract
+
+Extract data from pages using natural language instructions. The `extract` method is called on the `stagehand` instance.
+
+### Basic Extraction (with schema)
 
 ```typescript
-import { Stagehand } from "@browserbasehq/stagehand";
-import StagehandConfig from "./stagehand.config";
+import { z } from "zod";
+
+// Extract with explicit schema
+const data = await stagehand.extract(
+  "extract all apartment listings with prices and addresses",
+  z.object({
+    listings: z.array(
+      z.object({
+        price: z.string(),
+        address: z.string(),
+      }),
+    ),
+  }),
+);
 
-const stagehand = new Stagehand(StagehandConfig);
-await stagehand.init();
+console.log(data.listings);
+```
+
+### Simple Extraction (without schema)
+
+```typescript
+// Extract returns a default object with 'extraction' field
+const result = await stagehand.extract("extract the sign in button text");
+
+console.log(result);
+// Output: { extraction: "Sign in" }
 
-const page = stagehand.page; // Playwright Page with act, extract, and observe methods
-const context = stagehand.context; // Playwright BrowserContext
+// Or destructure directly
+const { extraction } = await stagehand.extract(
+  "extract the sign in button text",
+);
+console.log(extraction); // "Sign in"
 ```
 
-## Act
+### Targeted Extraction
 
-You can cache the results of `observe` and use them as params for `act` like this:
+Extract data from a specific element using a selector:
 
 ```typescript
-const instruction = "Click the sign in button";
-const cachedAction = await getCache(instruction);
+const reason = await stagehand.extract(
+  "extract the reason why script injection fails",
+  z.string(),
+  { selector: "/html/body/div[2]/div[3]/iframe/html/body/p[2]" },
+);
+```
 
-if (cachedAction) {
-  await page.act(cachedAction);
-} else {
-  try {
-    const results = await page.observe(instruction);
-    await setCache(instruction, results);
-    await page.act(results[0]);
-  } catch (error) {
-    await page.act(instruction); // If the action is not cached, execute the instruction directly
-  }
-}
+### URL Extraction
+
+When extracting links or URLs, use `z.string().url()`:
+
+```typescript
+const { links } = await stagehand.extract(
+  "extract all navigation links",
+  z.object({
+    links: z.array(z.string().url()),
+  }),
+);
 ```
 
-Be sure to cache the results of `observe` and use them as params for `act` to avoid unexpected DOM changes. Using `act` without caching will result in more unpredictable behavior.
+### Extracting from a Specific Page
 
-Act `action` should be as atomic and specific as possible, i.e. "Click the sign in button" or "Type 'hello' into the search input".
-AVOID actions that are more than one step, i.e. "Order me pizza" or "Type in the search bar and hit enter".
+```typescript
+// Extract from a specific page (when you need to target a page that isn't currently active)
+const data = await stagehand.extract(
+  "extract the placeholder text on the name field",
+  { page: page2 },
+);
+```
 
-## Extract
+## Observe
 
-If you are writing code that needs to extract data from the page, use Stagehand `extract`.
+Plan actions before executing them. Returns an array of candidate actions:
 
 ```typescript
-const signInButtonText = await page.extract("extract the sign in button text");
+// Get candidate actions on the current active page
+const [action] = await stagehand.observe("Click the sign in button");
+
+// Execute the action
+await stagehand.act(action);
 ```
 
-You can also pass in params like an output schema in Zod, and a flag to use text extraction:
+Observing on a specific page:
 
 ```typescript
-const data = await page.extract({
-  instruction: "extract the sign in button text",
-  schema: z.object({
-    text: z.string(),
-  }),
+// Target a specific page (when you need to target a page that isn't currently active)
+const actions = await stagehand.observe("find the next page button", {
+  page: page2,
 });
+await stagehand.act(actions[0], { page: page2 });
 ```
 
-`schema` is a Zod schema that describes the data you want to extract. To extract an array, make sure to pass in a single object that contains the array, as follows:
+## Agent
+
+Use the `agent` method to autonomously execute complex, multi-step tasks.
+
+### Basic Agent Usage
 
 ```typescript
-const data = await page.extract({
-  instruction: "extract the text inside all buttons",
-  schema: z.object({
-    text: z.array(z.string()),
-  }),
-  useTextExtract: true, // Set true for larger-scale extractions (multiple paragraphs), or set false for small extractions (name, birthday, etc)
+const page = stagehand.context.pages()[0];
+await page.goto("https://www.google.com");
+
+const agent = stagehand.agent({
+  model: "google/gemini-2.0-flash",
+  executionModel: "google/gemini-2.0-flash",
+});
+
+const result = await agent.execute({
+  instruction: "Search for the stock price of NVDA",
+  maxSteps: 20,
 });
+
+console.log(result.message);
 ```
 
-## Agent
+### Computer Use Agent (CUA)
 
-Use the `agent` method to automonously execute larger tasks like "Get the stock price of NVDA"
+For more advanced scenarios using computer-use models:
 
 ```typescript
-// Navigate to a website
-await stagehand.page.goto("https://www.google.com");
+const agent = stagehand.agent({
+  mode: "cua", // Enable Computer Use Agent mode
+  model: "anthropic/claude-sonnet-4-20250514",
+  // or "google/gemini-2.5-computer-use-preview-10-2025"
+  systemPrompt: `You are a helpful assistant that can use a web browser.
+    Do not ask follow up questions, the user will trust your judgement.`,
+});
+
+await agent.execute({
+  instruction: "Apply for a library card at the San Francisco Public Library",
+  maxSteps: 30,
+});
+```
 
+### Agent with Custom Model Configuration
+
+```typescript
 const agent = stagehand.agent({
-  // You can use either OpenAI or Anthropic
-  provider: "openai",
-  // The model to use (claude-3-7-sonnet-20250219 or claude-3-5-sonnet-20240620 for Anthropic)
-  model: "computer-use-preview",
-
-  // Customize the system prompt
-  instructions: `You are a helpful assistant that can use a web browser.
-	Do not ask follow up questions, the user will trust your judgement.`,
-
-  // Customize the API key
-  options: {
-    apiKey: process.env.OPENAI_API_KEY,
+  model: {
+    modelName: "google/gemini-2.5-computer-use-preview-10-2025",
+    apiKey: process.env.GEMINI_API_KEY,
   },
+  systemPrompt: `You are a helpful assistant.`,
 });
+```
 
-// Execute the agent
-await agent.execute(
-  "Apply for a library card at the San Francisco Public Library"
-);
+### Agent with Integrations (MCP/External Tools)
+
+```typescript
+const agent = stagehand.agent({
+  integrations: [`https://mcp.exa.ai/mcp?exaApiKey=${process.env.EXA_API_KEY}`],
+  systemPrompt: `You have access to the Exa search tool.`,
+});
+```
+
+## Advanced Features
+
+### DeepLocator (XPath Targeting)
+
+Target specific elements across shadow DOM and iframes:
+
+```typescript
+await page
+  .deepLocator("/html/body/div[2]/div[3]/iframe/html/body/p")
+  .highlight({
+    durationMs: 5000,
+    contentColor: { r: 255, g: 0, b: 0 },
+  });
+```
+
+### Multi-Page Workflows
+
+```typescript
+const page1 = stagehand.context.pages()[0];
+await page1.goto("https://example.com");
+
+const page2 = await stagehand.context.newPage();
+await page2.goto("https://example2.com");
+
+// Act/extract/observe operate on the current active page by default
+// Pass { page } option to target a specific page
+await stagehand.act("click button", { page: page1 });
+await stagehand.extract("get title", { page: page2 });

 # @browserbasehq/stagehand
 
+## 3.0.0
+
+### Major Changes
+
+- Removes internal Playwright dependency
+- A generous 20-40% speed increase across `act`, `extract`, & `observe` calls
+- Compatibility with Playwright, Puppeteer, and Patchright
+- Automatic action caching (agent, stagehand.act). Go from CUA → deterministic scripts w/o inference
+- A suite of non AI primitives:
+  - `page`
+  - `locator` (built in closed mode shadow root traversal, with xpaths & css selectors)
+  - `frameLocator`
+  - `deepLocator` (crosses iframes & shadow roots)
+- bun compatibility
+- Simplified extract schemas
+- CSS selector support (id-based support coming soon)
+- Targeted extract and observe across iframes & shadow roots
+- More intuitive type names (observeResult is now action, act accepts an instruction string instead of an action string, solidified ModelConfiguration)
+
+Check the [migration guide](https://docs.stagehand.dev/v3/migrations/v2) for more information
+
+## 2.5.0
+

+## What is Stagehand?
+
+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
 ## Why Stagehand?
 
-Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language, Stagehand is the natural choice for browser automations in production.
+Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language (and bridging the gap between the two) Stagehand is the natural choice for browser automations in production.
 
-1. **Choose when to write code vs. natural language**: use AI when you want to navigate unfamiliar pages, and use code ([Playwright](https://playwright.dev/)) when you know exactly what you want to do.
+1. **Choose when to write code vs. natural language**: use AI when you want to navigate unfamiliar pages, and use code when you know exactly what you want to do.
 
-2. **Preview and cache actions**: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.
+2. **Go from AI-driven to repeatable workflows**: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.
 
-3. **Computer use models with one line of code**: Stagehand lets you integrate SOTA computer use models from OpenAI and Anthropic into the browser with one line of code.
+3. **Write once, run forever**: Stagehand's auto-caching combined with self-healing remembers previous actions, runs without LLM inference, and knows when to involve AI whenever the website changes and your automation breaks. 
+
+## Getting Started
+
+Start with Stagehand with one line of code, or check out our [Quickstart Guide](https://docs.stagehand.dev/v3/first-steps/quickstart) for more information:
+
+```bash
+npx create-browser-app
+```
 
 ## Example
 
 Here's how to build a sample browser automation with Stagehand:
 
-<div align="center">
-  <div style="max-width:300px;">
-    <img src="/media/github_demo.gif" alt="See Stagehand in Action">
-  </div>
-</div>
-
 ```typescript
-// Use Playwright functions on the page object
-const page = stagehand.page;
+// Stagehand's CDP engine provides an optimized, low level interface to the browser built for automation
+const page = stagehand.context.pages()[0];
 await page.goto("https://github.com/browserbase");
 
 // Use act() to execute individual actions
-await page.act("click on the stagehand repo");
+await stagehand.act("click on the stagehand repo");
 
-// Use Computer Use agents for larger actions
-const agent = stagehand.agent({
-    provider: "openai",
-    model: "computer-use-preview",
-});
+// Use agent() for multi-step tasks
+const agent = stagehand.agent();
 await agent.execute("Get to the latest PR");
 
-// Use extract() to read data from the page
-const { author, title } = await page.extract({
-  instruction: "extract the author and title of the PR",
-  schema: z.object({
+// Use extract() to get structured data from the page
+const { author, title } = await stagehand.extract(
+  "extract the author and title of the PR",
+  z.object({
     author: z.string().describe("The username of the PR author"),
     title: z.string().describe("The title of the PR"),
   }),
-});
+);

+# Stagehand Project
+
+This is a project that uses Stagehand V3, a browser automation framework with AI-powered `act`, `extract`, `observe`, and `agent` methods.
+
+The main class can be imported as `Stagehand` from `@browserbasehq/stagehand`.
+
+**Key Classes:**
+
+- `Stagehand`: Main orchestrator class providing `act`, `extract`, `observe`, and `agent` methods
+- `context`: A `V3Context` object that manages browser contexts and pages
+- `page`: Individual page objects accessed via `stagehand.context.pages()[i]` or created with `stagehand.context.newPage()`
+
+## Initialize
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL", // or "BROWSERBASE"
+  verbose: 2, // 0, 1, or 2
+  model: "openai/gpt-4.1-mini", // or any supported model
+});
+
+await stagehand.init();
+
+// Access the browser context and pages
+const page = stagehand.context.pages()[0];
+const context = stagehand.context;
+
+// Create new pages if needed
+const page2 = await stagehand.context.newPage();
+```
+
+## Act
+
+Actions are called on the `stagehand` instance (not the page). Use atomic, specific instructions:
+
+```typescript
+// Act on the current active page
+await stagehand.act("click the sign in button");
+
+// Act on a specific page (when you need to target a page that isn't currently active)
+await stagehand.act("click the sign in button", { page: page2 });
+```
+
+**Important:** Act instructions should be atomic and specific:
+
+- ✅ Good: "Click the sign in button" or "Type 'hello' into the search input"
+- ❌ Bad: "Order me pizza" or "Type in the search bar and hit enter" (multi-step)
+
+### Observe + Act Pattern (Recommended)
+
+Cache the results of `observe` to avoid unexpected DOM changes:
+
+```typescript
+const instruction = "Click the sign in button";
+
+// Get candidate actions
+const actions = await stagehand.observe(instruction);
+
+// Execute the first action
+await stagehand.act(actions[0]);
+```
+
+To target a specific page:
+
+```typescript
+const actions = await stagehand.observe("select blue as the favorite color", {
+  page: page2,
+});
+await stagehand.act(actions[0], { page: page2 });
+```
+
+## Extract
+
+Extract data from pages using natural language instructions. The `extract` method is called on the `stagehand` instance.
+
+### Basic Extraction (with schema)
+
+```typescript
+import { z } from "zod";
+
+// Extract with explicit schema
+const data = await stagehand.extract(
+  "extract all apartment listings with prices and addresses",
+  z.object({
+    listings: z.array(
+      z.object({
+        price: z.string(),
+        address: z.string(),
+      }),
+    ),
+  }),
+);
+
+console.log(data.listings);
+```
+
+### Simple Extraction (without schema)
+
+```typescript
+// Extract returns a default object with 'extraction' field
+const result = await stagehand.extract("extract the sign in button text");
+
+console.log(result);
+// Output: { extraction: "Sign in" }
+
+// Or destructure directly
+const { extraction } = await stagehand.extract(
+  "extract the sign in button text",
+);
+console.log(extraction); // "Sign in"
+```
+
+### Targeted Extraction
+
+Extract data from a specific element using a selector:
+
+```typescript
+const reason = await stagehand.extract(
+  "extract the reason why script injection fails",
+  z.string(),
+  { selector: "/html/body/div[2]/div[3]/iframe/html/body/p[2]" },
+);
+```
+
+### URL Extraction
+
+When extracting links or URLs, use `z.string().url()`:
+
+```typescript
+const { links } = await stagehand.extract(
+  "extract all navigation links",
+  z.object({
+    links: z.array(z.string().url()),
+  }),
+);
+```
+
+### Extracting from a Specific Page
+
+```typescript
+// Extract from a specific page (when you need to target a page that isn't currently active)
+const data = await stagehand.extract(
+  "extract the placeholder text on the name field",
+  { page: page2 },
+);
+```
+
+## Observe
+
+Plan actions before executing them. Returns an array of candidate actions:
+
+```typescript
+// Get candidate actions on the current active page
+const [action] = await stagehand.observe("Click the sign in button");
+
+// Execute the action
+await stagehand.act(action);
+```
+
+Observing on a specific page:
+
+```typescript
+// Target a specific page (when you need to target a page that isn't currently active)
+const actions = await stagehand.observe("find the next page button", {
+  page: page2,
+});
+await stagehand.act(actions[0], { page: page2 });
+```
+
+## Agent
+
+Use the `agent` method to autonomously execute complex, multi-step tasks.
+
+### Basic Agent Usage
+
+```typescript
+const page = stagehand.context.pages()[0];
+await page.goto("https://www.google.com");
+
+const agent = stagehand.agent({
+  model: "google/gemini-2.0-flash",
+  executionModel: "google/gemini-2.0-flash",
+});
+
+const result = await agent.execute({
+  instruction: "Search for the stock price of NVDA",
+  maxSteps: 20,
+});
+
+console.log(result.message);
+```
+
+### Computer Use Agent (CUA)
+
+For more advanced scenarios using computer-use models:
+
+```typescript
+const agent = stagehand.agent({
+  mode: "cua", // Enable Computer Use Agent mode
+  model: "anthropic/claude-sonnet-4-20250514",
+  // or "google/gemini-2.5-computer-use-preview-10-2025"
+  systemPrompt: `You are a helpful assistant that can use a web browser.
+    Do not ask follow up questions, the user will trust your judgement.`,
+});
+
+await agent.execute({
+  instruction: "Apply for a library card at the San Francisco Public Library",
+  maxSteps: 30,
+});
+```
+
+### Agent with Custom Model Configuration
+
+```typescript
+const agent = stagehand.agent({
+  model: {
+    modelName: "google/gemini-2.5-computer-use-preview-10-2025",
+    apiKey: process.env.GEMINI_API_KEY,
+  },
+  systemPrompt: `You are a helpful assistant.`,
+});
+```
+
+### Agent with Integrations (MCP/External Tools)
+
+```typescript
+const agent = stagehand.agent({
+  integrations: [`https://mcp.exa.ai/mcp?exaApiKey=${process.env.EXA_API_KEY}`],
+  systemPrompt: `You have access to the Exa search tool.`,
+});
+```
+
+### Agent Hybrid Mode
+
+Hybrid mode uses both DOM-based and coordinate-based tools (act, click, type, dragAndDrop) for visual interactions. This requires `experimental: true` and models that support reliable coordinate-based actions.
+
+**Recommended models for hybrid mode:**
+
+- Any Anthropic model (e.g. `anthropic/claude-sonnet-4-20250514`, `anthropic/claude-haiku-4-5-20251001`)
+- OpenAI: `openai/gpt-5.4`, `openai/gpt-5.4-mini`
+- Google: `google/gemini-3.1-flash-lite-preview`, `google/gemini-3-flash-preview`, `google/gemini-3.1-pro-preview`
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  experimental: true, // Required for hybrid mode
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  mode: "hybrid",
+  model: "google/gemini-3-flash-preview",
+});
+
+await agent.execute({
+  instruction: "Click the submit button and fill the form",
+  maxSteps: 20,
+  highlightCursor: true, // Enabled by default in hybrid mode
+});
+```
+
+**Agent modes:**
+
+- `"dom"`: Uses DOM-based tools (act, fillForm) - works with any model
+- `"hybrid"`: Uses both DOM-based and coordinate-based tools (act, click, type, dragAndDrop) - auto-selected for supported models (Claude, GPT-5.4, Gemini 3)
+- When no mode is specified, hybrid is auto-selected for supported models; otherwise falls back to dom
+- `"cua"`: Uses Computer Use Agent providers
+
+## Advanced Features
+
+### DeepLocator (XPath Targeting)
+
+Target specific elements across shadow DOM and iframes:
+
+```typescript
+await page
+  .deepLocator("/html/body/div[2]/div[3]/iframe/html/body/p")
+  .highlight({
+    durationMs: 5000,
+    contentColor: { r: 255, g: 0, b: 0 },
+  });
+```
+
+### Multi-Page Workflows
+
+```typescript
+const page1 = stagehand.context.pages()[0];
+await page1.goto("https://example.com");
+
+const page2 = await stagehand.context.newPage();
+await page2.goto("https://example2.com");
+
+// Act/extract/observe operate on the current active page by default
+// Pass { page } option to target a specific page
+await stagehand.act("click button", { page: page1 });
+await stagehand.extract("get title", { page: page2 });
+```

-# Stagehand Logging System
-
-The Stagehand logging system uses [Pino](https://getpino.io/) to provide structured, efficient, and configurable logging.
-
-## Log Levels
-
-Stagehand uses three primary log levels:
-
-| Level | Name  | Description                             |
-| ----- | ----- | --------------------------------------- |
-| 0     | error | Critical errors and important warnings  |
-| 1     | info  | Standard information messages (default) |
-| 2     | debug | Detailed information for debugging      |
-
-The verbosity of logging is controlled by the `verbose` option when creating a Stagehand instance:
-
-```typescript
-const stagehand = new Stagehand({
-  verbose: 2, // Show all logs up to debug level
-  // other options...
-});
-```
-
-## Using the Logger
-
-The logging system is automatically initialized with your Stagehand instance. You can access it directly via:
-
-```typescript
-// Log an error
-stagehand.log({
-  message: "An error occurred",
-  level: 0,
-  category: "error",
-});
-
-// Log info (level 1 is default)
-stagehand.log({
-  message: "Operation completed",
-  category: "operation",
-});
-
-// Log debug information
-stagehand.log({
-  message: "Debug details",
-  level: 2,
-  category: "debug",
-  auxiliary: {
-    details: {
-      value: JSON.stringify({ key: "value" }),
-      type: "object",
-    },
-  },
-});
-```
-
-## Inference Logging
-
-For detailed logging of inference operations (act, extract, observe), Stagehand provides specialized logging:
-
-```typescript
-// Enable inference logging to file
-const stagehand = new Stagehand({
-  logInferenceToFile: true,
-  // other options...
-});
-```
-
-When enabled, inference logs are written to the `inference_summary` directory in your project.
-
-## Pretty Printing
-
-By default, logs in development are formatted with colors and readable timestamps using Pino's pretty formatting. For production environments or when sending logs to external systems, you can disable pretty printing.
-
-## Customizing Logging
-
-### Using Your Own Logger
-
-You can provide your own custom logger when creating a Stagehand instance:
-
-```typescript
-const stagehand = new Stagehand({
-  logger: (logLine) => {
-    // Your custom logging logic here
-    console.log(`[${logLine.category}] ${logLine.message}`);
-  },
-  // other options...
-});
-```
-
-When you provide a custom logger, Stagehand will automatically disable its internal Pino logger to prevent duplicate logging. Your logger will receive all log events directly.
-
-### Configuring Pino
-
-If you want to use Pino but with custom configuration:
-
-```typescript
-import { StagehandLogger } from "@browserbasehq/stagehand/lib/logger";
-
-// Create a custom configured logger
-const customLogger = new StagehandLogger({
-  pretty: true,
-  level: "debug",
-  // Other Pino options...
-});
-
-// Pass it to Stagehand
-const stagehand = new Stagehand({
-  logger: (logLine) => customLogger.log(logLine),
-  // other options...
-});
-```
-
-## Advanced Usage
-
-### Creating a New StagehandLogger Instance
-
-You can create a standalone logger for use in your application:
-
-```typescript
-import { StagehandLogger } from "@browserbasehq/stagehand/lib/logger";
-
-const logger = new StagehandLogger({
-  pretty: true,
-  level: "debug",
-});
-
-logger.info("Information message");
-logger.debug("Debug message", { details: "some data" });
-logger.error("Error message", { error: "details" });
-```
-
-### Configuring Log Output
-
-You can direct logs to a file or other destination:
-
-```typescript
-import fs from "fs";
-import { StagehandLogger } from "@browserbasehq/stagehand/lib/logger";
-
-const fileStream = fs.createWriteStream("./logs/application.log", {
-  flags: "a",
-});
-
-const logger = new StagehandLogger({
-  destination: fileStream,
-});
-```
-
-### Disabling Pino Explicitly
-
-If you want to handle all logging yourself without using Pino:
-
-```typescript
-import { StagehandLogger } from "@browserbasehq/stagehand/lib/logger";
-
-const logger = new StagehandLogger(
-  {
-    usePino: false,
-  },
-  (logLine) => {
-    // Your custom logging logic
-    console.log(`[${logLine.level}] ${logLine.message}`);
-  },
-);
-```
-
-## Troubleshooting
-
-If you're not seeing logs:
-
-1. Check your `verbose` setting - it may be too low for the log levels you're trying to see
-2. Verify that your log messages have the correct level set
-3. If using a custom logger, ensure it's correctly handling the log messages
-
-If you're seeing duplicate logs:
-
-1. Make sure you're not creating multiple instances of StagehandLogger that log to the same output
-2. If providing a custom logger to Stagehand, it will automatically disable the internal Pino logger
-
-If logs are not being written to files:
-
-1. Ensure you have write permissions to the target directory
-2. Check that the `logInferenceToFile` option is enabled
-3. Verify that the destination path exists or can be created

-# Releasing
-
-We use [Changesets](https://github.com/changesets/changesets) to version and release our packages.
-
-When we merge to main, the release workflow will:
-
-1. Create a release pull request with:
-   - A version bump for the package calculated by the changesets.
-   - A changelog entry summarizing the changes in the release.
-1. Create an `alpha` version of the package with whatever is merged to main, and you can install it with `npm install @browserbasehq/stagehand@alpha`. This is useful for testing the release before it's published to the `latest` tag.
-
-When the pull request is merged, the release workflow will publish the package to npm with the version calculated by the changesets.
-
-For more information on how changesets work, see the [changesets docs](https://github.com/changesets/changesets) and our [release.yml file](/.github/workflows/release.yml).
-
-# Manually Releasing
-
-> [!WARNING]
-> You should not need to manually release unless absolutely necessary. Our automated release workflow handles this for you when changes are merged to main.
-
-When you're ready to cut a release, start by versioning the packages:
-
-```
-npx changeset version
-```
-
-This will consume the changesets in [`.changeset`](../.changeset) and update the [changelog](../CHANGELOG.md) and [`package.json`](../package.json):
-
-```
-% git status --short
- M CHANGELOG.md
- M package.json
-```
-
-Based on the versions implications declared by the changesets, the package version will be updated to the next patch, minor, or major:
-
-```diff
-   "name": "@browserbasehq/stagehand",
--  "version": "1.3.0",
-+  "version": "1.3.1",
-```
-
-Since we updated the `package.json`, we should also update the lockfile ([`package-lock.json`](../package-lock.json)) for tidiness:
-
-```
-npm install
-```
-
-Now the lockfile should be updated:
-
-```
-% git status --short
- M CHANGELOG.md
- M package-lock.json
- M package.json
-```
-
-The diff will look something like this:
-
-```diff
- {
-   "name": "@browserbasehq/stagehand",
--  "version": "1.3.0",
-+  "version": "1.3.1",
-   "lockfileVersion": 3,
-   "requires": true,
-   "packages": {
-     "": {
-       "name": "@browserbasehq/stagehand",
--      "version": "1.3.0",
-+      "version": "1.3.1",
-```
-
-At this point we're ready to commit our changes.
-It's probably a good idea to have some consistency around the name of this commit message:
-
-```
-git commit -am 'Version Packages'
-```
-
-Ok, now it's time to publish the release.
-Before we do, we have to build the artifacts that comprise the tarball.
-Let's clean our working directory first so that we don't accidentally include anything in the tarball that shouldn't be there:
-
-```
-% git clean -fxd -e .env
-Removing dist/
-Removing lib/dom/build/
-Removing node_modules/
-```
-
-Let's reinstall dependencies and build the artifacts:
-
-```
-npm install && npm run build
-```
-
-Now we're ready to publish to NPM. You have to be logged in via the `npm` CLI and have to be part of the `@browserbasehq` org:
-
-```
-npx changeset publish
-```
-
-Congratulations! You just published a new version of `@browserbasehq/stagehand`. 🤘
-
-In the process of publishing, Changesets created an [annotated git tag](https://git-scm.com/book/en/v2/Git-Basics-Tagging):
-
-```
-🦋  Creating git tag...
-🦋  New tag:  v1.3.1
-```
-
-Let's push the commit and tag to GitHub for posterity:
-
-```
-git push --follow-tags
-```

-/**
- * This script orchestrates the running of evaluations against a set of tasks.
- * It uses Braintrust to run multiple testcases (each testcase representing a
- * given task-model combination) and then aggregates the results, producing
- * a summary of passes, failures, and categorized success rates.
- *
- * Overview:
- * - Reads a configuration file `evals.config.json` to determine what tasks (evaluations)
- *   are available and which categories they belong to.
- * - Supports filtering which tasks to run either by evaluation category or by specific task name.
- * - Supports multiple models, defaulting to certain sets of models depending on the category.
- * - Runs each selected task against each selected model in parallel, collecting results.
- * - Saves a summary of the evaluation results to `eval-summary.json`.

-   *
-   * Each chunk represents a subset of the DOM at a particular

-   *
-   * - `startOffset` & `endOffset`: The vertical scroll bounds for this chunk.
-   * - `outputString`: A serialized representation of extracted DOM text.

-   * @param startOffset - The initial scroll offset from which to begin collecting.
-   * @param endOffset - The maximum scroll offset to collect up to.
-   * @param chunkSize - The vertical increment to move between each chunk.

-   *
-   * @returns A promise that resolves with an array of `DomChunk` objects.
-   *
-   * ### How It Works
-   *
-   * 1. **Scroll Range Calculation**:
-   *    - Computes `maxOffset` as the maximum offset that can be scrolled
-   *      (`scrollHeight - viewportHeight`).
-   *    - Restricts `endOffset` to not exceed `maxOffset`.
-   *
-   * 2. **Chunk Iteration**:
-   *    - Loops from `startOffset` to `endOffset` in steps of `chunkSize`.
-   *    - For each offset `current`, we call `this.scrollTo(current)`
-   *      to position the container.
-   *
-   * 3. **Element Collection**:
-   *    - Invokes `collectCandidateElements` on either `candidateContainer`
-   *      (if provided) or the result of `this.getRootElement()`.
-   *    - This returns both an `outputString` (serialized text)
-   *      and a `selectorMap` of found elements for that section of the DOM.
-   *
-   * 4. **Chunk Assembly**:
-   *    - Creates a `DomChunk` object for the current offset range,
-   *      storing `outputString`, `selectorMap`, and scroll offsets.
-   *    - Pushes it onto the `chunks` array.
-   *
-   * 5. **Scroll Reset**:
-   *    - Once iteration completes, if `scrollBackToTop` is `true`,
-   *      we scroll back to offset `0`.

-/**
- * The `StagehandExtractHandler` class is responsible for extracting structured data from a webpage.
- * It provides two approaches: `textExtract` and `domExtract`. `textExtract` is used by default.
- *
- * Here is what `textExtract` does at a high level:
- *
- * **1. Wait for the DOM to settle and start DOM debugging.**
- *    - Ensures the page is fully loaded and stable before extraction.
- *
- * **2. Store the original DOM before any mutations.**
- *    - Preserves the initial state of the DOM to restore later.
- *    - We do this because creating spans around every word in the DOM (see step 4)
- *      becomes very difficult to revert. Text nodes can be finicky, and directly
- *      removing the added spans often corrupts the structure of the DOM.
- *
- * **3. Process the DOM to generate a selector map of candidate elements.**
- *    - Identifies potential elements that contain the data to extract.
- *
- * **4. Create text bounding boxes around every word in the webpage.**
- *    - Wraps words in spans so that their bounding boxes can be used to
- *      determine their positions on the text-rendered-webpage.
- *
- * **5. Collect all text annotations (with positions and dimensions) from each of the candidate elements.**
- *    - Gathers text and positional data for each word.
- *
- * **6. Group annotations by text and deduplicate them based on proximity.**
- *    - There is no guarantee that the text annotations are unique (candidate elements can be nested).
- *    - Thus, we must remove duplicate words that are close to each other on the page.
- *
- * **7. Restore the original DOM after mutations.**
- *    - Returns the DOM to its original state after processing.
- *
- * **8. Format the deduplicated annotations into a text representation.**
- *    - Prepares the text data for the extraction process.
- *
- * **9. Pass the formatted text to an LLM for extraction according to the given instruction and schema.**
- *    - Uses a language model to extract structured data based on instructions.
- *
- * **10. Handle the extraction response and logging the results.**
- *     - Processes the output from the LLM and logs relevant information.
- *
- * @remarks
- * Each step corresponds to specific code segments, as noted in the comments throughout the code.

+# browse
+
+## 0.9.5
+
+### Patch Changes
+
+- [#2335](https://github.com/browserbase/stagehand/pull/2335) [`19f9f5a`](https://github.com/browserbase/stagehand/commit/19f9f5a2631573b9952e4df7fbd2c8765c5fac5b) Thanks [@shrey150](https://github.com/shrey150)! - Add `browse skills show` to print the bundled skill and point agents to it from `--help`.
+
+## 0.9.4
+
+### Patch Changes
+
+- [#2296](https://github.com/browserbase/stagehand/pull/2296) [`2f5e085`](https://github.com/browserbase/stagehand/commit/2f5e085a38aa6d8d52eb33017c64385a75e192cf) Thanks [@shrey150](https://github.com/shrey150)! - `browse snapshot` now prints the accessibility tree only by default, omitting the `xpathMap`/`urlMap` ref maps. Pass `--full` to include them. Ref-based element commands are unaffected.
+
+## 0.9.3
+
+### Patch Changes
+
+- [#2310](https://github.com/browserbase/stagehand/pull/2310) [`77a8e92`](https://github.com/browserbase/stagehand/commit/77a8e926ac525264e41a3686808270efd3b4fd9f) Thanks [@shrey150](https://github.com/shrey150)! - browse is now also distributed as a Docker image: `ghcr.io/browserbase/browse` (multi-arch `linux/amd64,linux/arm64`, pinned to each release). Lets code sandboxes consume the CLI by image reference without a Dockerfile.
+
+## 0.9.2
+
+### Patch Changes
+
+- [#2284](https://github.com/browserbase/stagehand/pull/2284) [`70b72d3`](https://github.com/browserbase/stagehand/commit/70b72d36907254fb3719ea5f520d37d362a11319) Thanks [@shrey150](https://github.com/shrey150)! - Add named contexts to the CLI so you can reuse a Browserbase context by a memorable name instead of its ID. `browse cloud contexts create --name <name>` saves a local name→ID alias (stored at `(XDG_CONFIG_HOME||~/.config)/browserbase/contexts.json`, honoring `BROWSERBASE_CONFIG_DIR`), `browse cloud contexts add <name> <id>` names a context you already have, `browse cloud contexts list` shows your saved names, and any place that accepts a context ID — `contexts get|update|delete` and `sessions create --context-id` — now also accepts a saved name. Deleting a context prunes its local alias, and a typo'd name fails with a "did you mean?" hint instead of a cryptic API error. The map is purely client-side: it stores the same IDs the API already returns, and a missing or corrupt file degrades to "no saved contexts" rather than erroring.
+
+- [#2282](https://github.com/browserbase/stagehand/pull/2282) [`b8132f6`](https://github.com/browserbase/stagehand/commit/b8132f6a3350ba5682f6ead07d72f86d34286b16) Thanks [@shrey150](https://github.com/shrey150)! - Add `--verified` and `--proxies` to remote driver sessions so `browse open <url> --remote --verified --proxies` opens a Verified and/or proxied Browserbase session in one command — no more create-then-attach with `--cdp`.
+
+  - The flags are valid only with `--remote` (they are never implied, since that would silently switch to billed cloud sessions) and are sticky for the session's lifetime like `--headed`/`--headless`: a re-open requesting different settings fails with the usual stop-and-reopen error.
+  - Because the session is created through the normal remote path (not a raw `--cdp` attach), it keeps its Browserbase identity and the `browse_cli` attribution tag. `browse status` and `browse doctor` now surface the Browserbase session ID, the dashboard URL, the live-view (debug) URL, and the verified/proxies state.
+  - `--verified` requires a Browserbase Scale plan.
+
+- [#2280](https://github.com/browserbase/stagehand/pull/2280) [`39d7638`](https://github.com/browserbase/stagehand/commit/39d7638022b742f9d24776b6dc5d70a992aaeabf) Thanks [@shrey150](https://github.com/shrey150)! - Honor `BROWSERBASE_API_KEY` passed to an already-running driver daemon. Previously, if the first remote command started the daemon without a key, a later `BROWSERBASE_API_KEY=… browse open <url> --remote` (or an exported key in a new shell) kept failing with "Missing BROWSERBASE_API_KEY" because the detached daemon captured `process.env` once at spawn time and never saw the new key. The client now forwards the caller's key over the (localhost, owner-only) driver socket with every command, and the daemon threads it straight into the Stagehand constructor when it creates the session — so an inline or exported key works without a manual `browse stop` and restart. The forwarded key is never written back into the daemon's `process.env`; its only home is the live session. Already-initialized warm sessions are untouched; the forwarded key only takes effect at session init. The local-only (CDP-only) build forwards nothing and remains free of any API-key code path.
+
+- [#2297](https://github.com/browserbase/stagehand/pull/2297) [`c18ab34`](https://github.com/browserbase/stagehand/commit/c18ab345e00451237ebd2bcf3567a76bbf1e52a3) Thanks [@shrey150](https://github.com/shrey150)! - Remove the `browse refs` command. It only re-printed the `xpathMap`/`urlMap` cached from the last `browse snapshot` — which `browse snapshot` already returns — so it was redundant, and it returned stale maps if the page had changed since that snapshot.
+
+## 0.9.1
+
+### Patch Changes
+
+- [#2277](https://github.com/browserbase/stagehand/pull/2277) [`263e4d4`](https://github.com/browserbase/stagehand/commit/263e4d437dbdb722b9801488dd8cb40b8d78106e) Thanks [@shrey150](https://github.com/shrey150)! - Attribute CLI-driven Browserbase usage to an anonymous install. Remote browser sessions now stamp `install_id` and `cli_version` (alongside `browse_cli`) onto `userMetadata`, and cloud Search/Fetch requests send `x-bb-client` and `x-bb-install-id` headers. The install id reuses the existing anonymous telemetry marker; resolution is best-effort and never blocks or fails a command.
+
+## 0.9.0
+
+### Minor Changes
+
+- [#2246](https://github.com/browserbase/stagehand/pull/2246) [`303ab2c`](https://github.com/browserbase/stagehand/commit/303ab2c03c68e239c5e27c6fe9f0fa02b12c4749) Thanks [@shrey150](https://github.com/shrey150)! - `browse screenshot` now writes a file by default instead of printing base64 to stdout. Bare invocations save to `screenshot-<yyyymmdd-hhmmss>.<type>` in the current directory (with a collision counter instead of overwriting) and print `{ "saved": "<path>" }`. A new `--base64` flag preserves the legacy behavior of printing `{ "base64": "..." }` to stdout; it is mutually exclusive with `--path`. `--path` behavior is unchanged.
+
+  Note for scripts that parsed the bare-invocation base64 output: pass `--base64` to keep the old stdout contract.
+
+### Patch Changes
+
+- [#2250](https://github.com/browserbase/stagehand/pull/2250) [`8b83bb7`](https://github.com/browserbase/stagehand/commit/8b83bb7bb51c81b05014fac4a77bc653a90ca98b) Thanks [@shrey150](https://github.com/shrey150)! - Fix `browse skills add` on Windows and bound the unbounded installer stages.
+
+  - Quote the `npx` command and arguments when spawning through cmd.exe (`shell: true` for `.cmd`/`.bat` shims), so the default `C:\Program Files\nodejs\npx.cmd` path and install paths with spaces (e.g. `C:\Users\First Last\...`) no longer split at the space and fail with "'C:\Program' is not recognized".
+  - Kill the `npx skills add` child after a 180s deadline (SIGTERM, then SIGKILL) and fail with a clear message and a distinct `skill_install_timeout` telemetry result code instead of hanging forever.
+  - Bound the catalog and skill-file fetches with a 10s abort timeout, preserving the existing catalog-unavailable fallback semantics when a fetch hangs.
+
+## 0.8.5
+
+### Patch Changes
+
+- [#2258](https://github.com/browserbase/stagehand/pull/2258) [`2441cd4`](https://github.com/browserbase/stagehand/commit/2441cd4197da67896dca1e4a856673032fd66c74) Thanks [@shrey150](https://github.com/shrey150)! - Stop headed local sessions from stealing OS focus on every command.
+
+  In headed managed-local mode the browse daemon re-resolved the active page on every subcommand and called `setActivePage()` unconditionally, which ends in a CDP `Target.activateTarget`. On macOS that raises the whole Chrome app to the OS foreground, stealing keyboard focus from the editor/terminal on each `browse navigate/snapshot/get/…` — making the CLI nearly unusable alongside a coding agent and impossible to parallelize. The active tab is now re-activated only when it actually changes; explicit `tab new` / `tab select` still foreground intentionally.
+
+- [#2249](https://github.com/browserbase/stagehand/pull/2249) [`4ee8d99`](https://github.com/browserbase/stagehand/commit/4ee8d9948c143e114b33b8b63b90c75daec1545d) Thanks [@shrey150](https://github.com/shrey150)! - Add did-you-mean suggestions and telemetry for unknown commands.
+
+  - Unknown commands (e.g. `browse sessions`, `browse search`, `browse auth status` — old Commander-era syntax — plus plain typos like `browse opne`) now print an actionable suggestion on stderr: an explicit alias table maps old syntax to the current command tree, with a Levenshtein nearest-match fallback for typos. The clause is omitted when there is no decent match.
+  - A new `cli.command_not_found` telemetry event makes this failure class measurable. Privacy: only the sanitized attempted command id and the computed suggestion are sent — never raw argv, which can contain URLs, selectors, or secrets.
+  - oclif's standard "command not found" error and exit code 2 are preserved; no new runtime dependency (deliberately avoids `@oclif/plugin-not-found`, which prompts interactively and is agent-hostile).
+
+- [#2248](https://github.com/browserbase/stagehand/pull/2248) [`cffcc91`](https://github.com/browserbase/stagehand/commit/cffcc91add8edc1f9b9f0846b36ecb8ea51605d0) Thanks [@shrey150](https://github.com/shrey150)! - Make driver (browser session) failures actionable, classified, and self-correcting.
+
+  - An invalid `BROWSERBASE_API_KEY` no longer surfaces a bare `401 Unauthorized`: remote init failures are classified (401 invalid key, 403 permissions/plan, other) into actionable messages that point at the key settings page, `--local`, and `browse doctor`.
+  - A missing local Chrome now explains how to install Chrome, attach with `--cdp`, or switch to remote, instead of leaking chrome-launcher internals.
+  - Cached init failures back off exponentially (5s doubling, capped at 5 minutes) and append a "failing repeatedly" hint after 3 consecutive failures, so retry-looping agents get a clear self-correction signal instead of instant identical errors forever.
+  - The daemon protocol now carries optional `code`/`httpStatus` on error responses (backward compatible), and the client records them as telemetry result codes — `open` failures stop being 94% `unexpected`. New codes include `remote_auth_401`, `remote_auth_403`, `remote_session_create_failed`, `no_chrome_found`, `stale_ref`, `no_active_page`, `daemon_lock_timeout`, `daemon_unresponsive`, `daemon_socket_timeout`, and `daemon_spawn_failed`.

+- [#2201](https://github.com/browserbase/stagehand/pull/2201) [`9971a7b`](https://github.com/browserbase/stagehand/commit/9971a7b3d8ecca255b4548cfb9128657c053cca7) Thanks [@shrey150](https://github.com/shrey150)! - Add Chrome launch arg flags for managed local browser sessions: `--chrome-arg <flag>` (repeatable) appends launch args on top of Chrome's defaults, `--ignore-default-chrome-arg <flag>` (repeatable) drops specific default args, and `--no-default-chrome-args` launches without any of Chrome's defaults.
+
+- [#2251](https://github.com/browserbase/stagehand/pull/2251) [`3ecf09e`](https://github.com/browserbase/stagehand/commit/3ecf09eabb7f3cd107bf64378664416597e912c8) Thanks [@shrey150](https://github.com/shrey150)! - Emit a `skill_id` property on `cli.command_completed` telemetry.
+
+  The validated, catalog-public skill id (e.g. `yelp.com/extract-reviews`, or `bundled/browse` for `skills install`) is attached to the completion event for `browse skills add`/`install`, covering both successful installs and every downstream failure path (`skill_not_found`, `skill_install_failed`, ...). Only the parsed, regex-validated id is ever attached — never the raw argument.
+
+## 0.8.4
+
+### Patch Changes

+- [#2213](https://github.com/browserbase/stagehand/pull/2213) [`7449046`](https://github.com/browserbase/stagehand/commit/7449046647c30800404c333dd604bacccba0aa7c) Thanks [@shrey150](https://github.com/shrey150)! - fix(cli): request the full template catalog via scope=all so `browse templates list` returns all templates, not just playground-runnable ones
+
+- [#2210](https://github.com/browserbase/stagehand/pull/2210) [`a9552fd`](https://github.com/browserbase/stagehand/commit/a9552fde629a2b13bc32dedc002e401af90b866c) Thanks [@shrey150](https://github.com/shrey150)! - Make `browse skills add` failures diagnosable and fail cleanly on unknown skills.
+
+  - Unknown (non-generated) skill ids now fail fast with an actionable "not found in the catalog" message pointing at `browse skills find`/`browse skills list`, instead of silently git-cloning the entire browse.sh repo and exiting with an opaque error.
+  - The `npx skills add` child's output is now buffered (tail) while still streaming live to the terminal, so a nonzero exit surfaces the real reason instead of a bare exit code.
+  - Failures now record distinct telemetry result codes (`skill_not_found`, `invalid_skill_id`, `npx_missing`, `skill_install_failed`) so the failure modes are measurable.
+  - `browse skills add` with no argument now prints actionable guidance (the `<domain>/<task>` form plus `browse skills find`) instead of oclif's bare "Missing 1 required arg".
+
+## 0.8.3
+
+### Patch Changes
+
+- [#2192](https://github.com/browserbase/stagehand/pull/2192) [`e7d3b55`](https://github.com/browserbase/stagehand/commit/e7d3b55f69f2a1fd75e92dea8f831f96fa6180d3) Thanks [@shrey150](https://github.com/shrey150)! - Lead-with-local onboarding: the missing-API-key error on cloud commands now tells users that local browser automation needs no key and points them to `browse open <url> --local`. The remote-mode driver error is clearer about when a key is required versus when local mode works without one.

+
+`browse` gives any agent — or any terminal — a reliable way to drive a real browser, learn how to use specific websites, and tap into Browserbase's cloud. One command to navigate the open web, capture telemetry while you do it, and reuse skills the community has already built.
+
+## Why browse
+
+- **Browser interactions** — Navigate tricky, complex websites with `browse click`, `browse mouse scroll`, `browse type`, `browse select`, and 30+ more DOM commands.
+- **Open web skills catalog** — `browse` is the official CLI for [browse.sh](https://browse.sh), the largest open web catalog. Run `browse skills add apartments.com` and your agent learns how to use that site and its APIs.
+- **Rich debugging** — Arm your agents with network, console, and other web telemetry.
+- **Cloud features** — Optionally use Browserbase cloud: load cookies via saved [Contexts](https://docs.browserbase.com/platform/browser/core-features/contexts), use [Verified Browsers](https://www.browserbase.com/verified), and call the [Fetch and Search APIs](https://www.browserbase.com/search).
+
+## Quick start
+
+```bash
+npm install -g browse
+
+browse open https://example.com
+browse snapshot
+browse click @0-12
+browse fill @0-8 "hello"
+browse get title
+browse screenshot --path page.png
+browse stop
+```
+
+## How it works
+
+`browse` runs a lightweight per-session daemon. The first command starts it, and subsequent commands reuse the same browser — so cookies, tabs, and snapshot refs persist between invocations. Run multiple isolated browsers at once with `--session <name>` (or the `BROWSE_SESSION` env var), and shut a session down with `browse stop`.
+
+### Browser targets
+
+Every driver command accepts the same flags to pick where the browser runs. Mix and match per command:
+
+| Flag | Target |
+|------|--------|
+| _(default)_ | Managed local browser, or remote when `BROWSERBASE_API_KEY` is set |
+| `--local` | Managed local browser (add `--headed` / `--headless`) |
+| `--remote` | Remote Browserbase session (uses `BROWSERBASE_API_KEY`) |
+| `--auto-connect` | Auto-discover and attach to a local Chrome with remote debugging enabled |
+| `--cdp <url\|port>` | Attach directly to a CDP endpoint (port, `http(s)://`, or `ws(s)://`) |
+| `--target-id <id>` | Select a specific CDP target when attaching to an existing browser |
+| `--chrome-arg <flag>` | Append a Chrome launch arg on top of the defaults (repeatable, managed-local only) |
+| `--ignore-default-chrome-arg <flag>` | Drop a specific Chrome default launch arg (repeatable, managed-local only) |
+| `--no-default-chrome-args` | Launch without any of Chrome's default args (managed-local only) |
+
+```bash
+browse open https://example.com                 # default target
+browse open https://example.com --local --headed
+browse open https://example.com --local --headed --chrome-arg=--no-focus-on-navigate
+browse open https://example.com --remote
+browse open https://example.com --auto-connect
+browse open https://example.com --cdp 9222
+browse open https://example.com --cdp ws://127.0.0.1:9222/devtools/browser/<id> --target-id <target-id>
+```
+
+Run `browse doctor` to diagnose session and browser-connection prerequisites for any target.
+
+## Commands
+
+### Navigation
+
+```bash
+browse open <url>     # Open a URL (--wait load|domcontentloaded|networkidle, --timeout <ms>)
+browse reload         # Reload the active page
+browse back           # Navigate backward
+browse forward        # Navigate forward
+```
+
+### Snapshot
+
+The accessibility snapshot is the recommended way for agents to discover elements. It prints a tree of refs like `@0-12` that the element commands accept directly.
+
+```bash
+browse snapshot                 # Accessibility tree + cached refs (lean by default)
+browse snapshot --full          # Also include the ref maps (xpathMap, urlMap)
+browse snapshot --filter submit # Filter lines by text or /regex/, keeping ancestors
+browse snapshot --max-depth 4   # Trim output deeper than this depth
+```
+
+### Element actions
+
+Targets accept a snapshot ref (`@0-12`), an XPath, or a CSS selector.
+
+```bash
+browse click @0-12                          # Click (also accepts selectors)
+browse fill @0-8 "hello"                     # Fill an input (--press-enter to submit)
+browse select @0-9 "CA"                       # Select an option (--value for <option value>)
+browse type "hello world"                     # Type at the current focus (--delay, --mistakes)
+browse press Enter                            # Press a key (alias: browse key) e.g. Meta+K, Escape
+browse upload @0-4 ./resume.pdf               # Upload file(s) (repeat --file for more)
+browse highlight @0-12                         # Highlight an element (--duration <ms>)
+```
+
+### Mouse (raw coordinates)
+
+Use these when you need pixel coordinates instead of a ref. Add `--return-xpath` to get the XPath under the cursor.
+
+```bash
+browse mouse click 240 320      # Click coordinates (--button, --click-count)
+browse mouse hover 240 320      # Move the mouse
+browse mouse scroll 400 500 0 600   # Scroll from a point by (dx, dy)
+browse mouse drag 100 100 400 400   # Drag between two points (--steps, --delay)
+```
+
+### Page info & state
+
+```bash
+browse get url          # Read page data / element state:
+browse get title        #   url, title, text, html, value, box,
+browse get text @0-12   #   visible, checked, markdown
+browse get markdown body
+browse get box 'button[type=submit]'
+browse is visible @0-12       # Check element state: visible, checked
+browse eval 'document.title'  # Evaluate JavaScript in the page
+browse viewport 1280 720      # Set viewport size (--scale for device pixel ratio)
+browse cursor                 # Enable a visible cursor overlay
+browse screenshot --path page.png   # Screenshot (--full-page, --type, --quality, --clip)
+```
+
+### Waiting
+
+```bash
+browse wait load                          # Wait for a load state
+browse wait load networkidle --timeout 45000
+browse wait selector @0-12 --state visible  # visible|hidden|attached|detached
+browse wait timeout 1000                  # Wait a fixed number of ms
+```
+
+### Tabs
+
+```bash
+browse tab list             # List tabs (with stable targetIds)
+browse tab new [url]        # Open a new tab and make it active
+browse tab switch <target-id>  # Switch active tab (index or targetId)
+browse tab close [target-id]   # Close a tab (defaults to the active tab)
+```
+
+Prefer the `targetId` from `browse tab list` over the index for stable agent workflows.
+
+### Network capture
+
+Capture request/response traffic for the active session to a local directory.
+
+```bash
+browse network on       # Start capturing
+browse network off      # Stop capturing
+browse network path     # Print the capture directory
+browse network clear    # Clear captured requests
+```
+
+> [!NOTE]
+> `browse network on` writes request/response headers and bodies to a local owner-only capture directory. These files can include cookies, authorization headers, and other secrets — use network capture only on trusted machines and run `browse network clear` when done.
+
+### Session & daemon
+
+```bash
+browse status      # Show daemon status for a session
+browse stop        # Stop the daemon (--force to kill an unresponsive browser)
+browse doctor      # Diagnose session and browser-connection prerequisites
+browse cdp 9222    # Attach to a CDP endpoint and stream DevTools events (--domain, --pretty)
+```
+
+### Global flags
+
+These apply across driver commands:
+
+| Flag | Description |
+|------|-------------|
+| `-s, --session <name>` | Named browser session (or `BROWSE_SESSION` env var) |
+| `--local` / `--remote` | Choose a managed local or remote Browserbase browser |
+| `--headed` / `--headless` | Window visibility for managed local sessions |
+| `--auto-connect` | Attach to a local Chrome with remote debugging enabled |
+| `--cdp <url\|port>` | Attach directly to a CDP endpoint |
+| `--target-id <id>` | Select a specific CDP target |
+| `--json` | Emit machine-readable JSON (available on most commands) |
+
+## Open web skills catalog
+
+Use [browse.sh](https://browse.sh), the largest open-source catalog of skills to reliably perform any task on the internet. Find a specialized skill to navigate `apartments.com`, for example, and drastically reduce your agent's time and token costs.
+
+```bash
+browse skills install                                       # install the bundled browse CLI skill
+browse skills list                                          # list the public Browse.sh catalog
+browse skills list --all                                    # include every catalog entry
+browse skills find reviews                                  # search by slug, domain, title, tag…
+browse skills find yelp.com/extract-reviews
+browse skills add yelp.com/extract-reviews                  # install a catalog skill
+browse skills add mcdonalds.order.online/order-delivery-42q71n
+```
+
+## Browserbase cloud commands
+
+Manage projects, sessions, contexts, and extensions, or call the Fetch and Search APIs directly. These commands use `BROWSERBASE_API_KEY`.
+
+```bash
+# Projects
+browse cloud projects list
+browse cloud projects get <project-id>
+browse cloud projects usage <project-id>
+
+# Sessions
+browse cloud sessions list                       # --limit, --status, --json
+browse cloud sessions get <session-id>
+browse cloud sessions create                     # --proxies, --verified, --region, --solve-captchas…
+browse cloud sessions update <session-id> --status REQUEST_RELEASE
+browse cloud sessions debug <session-id>         # live debugger URLs
+browse cloud sessions logs <session-id>
+browse cloud sessions downloads get <session-id> # --output ./downloads.zip
+browse cloud sessions uploads create <session-id> ./file.pdf
+
+# Contexts
+browse cloud contexts create
+browse cloud contexts get <context-id>
+browse cloud contexts update <context-id>        # refresh the upload URL
+browse cloud contexts delete <context-id>
+
+# Extensions
+browse cloud extensions upload ./extension.zip
+browse cloud extensions get <extension-id>
+browse cloud extensions delete <extension-id>
+
+# Fetch & Search APIs
+browse cloud fetch <url>                          # markdown by default
+browse cloud search <query>
+```
+
+`browse cloud fetch` returns markdown-formatted page content by default. Use `--format raw` for the original response body, or `--format json --schema <schema>` for structured extraction.
+
+## Functions
+
+Browserbase [Functions](https://docs.browserbase.com/platform/runtime/overview) let you deploy browser agents and automation scripts directly onto Browserbase's infrastructure. Build locally, test instantly, and deploy as APIs.
+
+```bash

+
+## Templates
+
+Discover and scaffold ready-to-run Browserbase example projects.
+
+```bash
+browse templates list                      # --tag, --source, --wide, --json
+browse templates find amazon               # search by slug, title, category, or tag
+browse templates clone google-trends-keywords
+browse templates clone amazon-product-scraping --language python ./my-scraper
+```
+
+## Configuration
+
+Set your Browserbase API key to enable remote sessions and cloud commands:
+
+```bash
+export BROWSERBASE_API_KEY=bb_live_...
+```
+
+Local driver commands (`--local`) work without an API key.
+
+`browse` also auto-loads a `.env` file from the current directory on startup, and prints a
+one-time deprecation warning to stderr when it actually pulls a variable from `.env` this way.
+This is deprecated because a CLI used across many unrelated projects can silently pick up a
+stale key from the wrong project's `.env`; a future release will disable auto-loading by
+default so `browse` only reads `process.env`. Set `BROWSE_LOAD_DOTENV=0` (or `false`/`no`) to
+opt out of `.env` auto-loading now, ahead of that change, or `BROWSE_LOAD_DOTENV=1` to keep
+auto-loading with no warning.
+
+| Variable | Description |
+|----------|-------------|
+| `BROWSERBASE_API_KEY` | Enables `--remote` sessions and all `browse cloud` / `functions` commands |
+| `BROWSE_SESSION` | Default session name (alternative to `-s, --session`) |
+| `BROWSE_LOAD_DOTENV` | Controls `.env` auto-loading: unset = load + warn once (default, deprecated), `0`/`false`/`no` = skip loading, anything else = load silently |

+# Browser agents
+
+> Cookbook for Anthropic Managed Agents
+> 
+
+This guide shows how to equip your Managed Agents with a browser, search, and fetch tooling to navigate the web. The `browse` CLI powers your agents to run UI testing, conduct deep document research, fill web forms and complex browser automations.
+
+## 1. Create an Environment
+
+Create a new Environment and set `browse` as a default `npm` package.
+
+Optionally, allow “Unrestricted” networking for the browser agent to navigate the open web. Use “Limited” networking to scope the agent to particular websites.
+
+![CleanShot 2026-06-05 at 13.12.43@2x.png](CleanShot_2026-06-05_at_13.12.432x.png)
+
+The [browse](https://www.npmjs.com/package/browse) CLI is purpose-built for agents to navigate and act on the web. It offers command interfaces like `browse click` or `browse network` that makes it intuitive for agents to control and observe webpage state.
+
+This CLI can work with (1) Managed Agents local chromium, (2) any CDP connection, (3) and natively with Browserbase Cloud sessions.
+
+## 2. Create a Credential vault
+
+Setup a new “Environment variable” type of Credential vault. This lets you agent securely use the `browse` CLI with an API key, which you can create one for free at [Browserbase developer dashboard](https://browserbase.com/).
+
+1. Create a new Credential vault, choose type “Environment variable”
+2. Name the variable `BROWSERBASE_API_KEY`
+3. Choose “Limited” networking with `*.browserbase.com` for allowed hosts
+
+![CleanShot 2026-06-05 at 13.15.54@2x.png](CleanShot_2026-06-05_at_13.15.542x.png)
+
+![CleanShot 2026-06-05 at 13.17.01@2x.png](CleanShot_2026-06-05_at_13.17.012x.png)
+
+## 3. Design your system prompt
+
+Let your agent know that the `browse` shell command is available in the Environment. The CLI is designed to offer instructive progressive disclosure for usage documentation.
+
+```yaml
+name: browser agent
+model:
+  id: claude-opus-4-8
+  speed: standard
+description: Runs shell commands to check CLI tools and environment variables.
+system: You are a browser agent. Use the `browse` CLI to operate a headless Chromium environment. Run `browse --help` to view the commands interface.
+mcp_servers: []
+tools:
+  - configs: []
+    default_config:
+      enabled: true
+      permission_policy:
+        type: always_allow
+    type: agent_toolset_20260401
+skills: []
+metadata: {}
+```
+
+![](image3.png)
+
+## 4. Try out a few browser agent use cases
+
+> Please run a full E2E test for UI regressions on this preview URL
+> 
+
+> Please check if Adam Smith is a licensed accountant in California
+> 
+
+> Please find the price of the Fellow Kettle on Target.com, and add to cart
+> 
+
+```bash
+ant beta:sessions create \
+  --agent "$AGENT_ID" \
+  --environment-id "$ENVIRONMENT_ID"
+```
+
+When your Managed Agents use remote browsers through the CLI, you may watch and debug the live sessions in the [Browserbase sessions panel](https://browserbase.com/sessions).

+
+# Browse CLI
+
+Use `browse` as the primary Browserbase command-line interface.
+
+It can:
+
+- drive a local or Browserbase-hosted browser session
+- inspect pages through accessibility snapshots, screenshots, DOM/text reads, and network capture
+- interact with pages by refs, selectors, XPath, keyboard, mouse, files, and viewport controls
+- manage Browserbase projects, sessions, contexts, extensions, fetch, and search APIs
+- develop, publish, and invoke Browserbase Functions
+- browse and scaffold Browserbase templates
+- diagnose local or remote browser setup issues
+- discover and install Browse.sh catalog skills
+- install or refresh this Browse CLI skill
+
+## Setup Check
+
+Verify the CLI exists before relying on it:
+
+```bash
+which browse || npm install -g browse
+browse --help
+```
+
+Install or refresh this skill with:
+
+```bash
+browse skills install
+```
+
+Use `browse <topic> --help` for exact flags before running unfamiliar commands.
+
+## Browser Target Selection
+
+Browser driver commands auto-start the browse daemon when needed. Choose the browser target per command with flags:
+
+```bash
+browse open https://example.com --local
+browse open https://example.com --local --headed
+browse open https://example.com --remote
+browse open https://example.com --remote --verified --proxies
+browse open https://example.com --auto-connect
+browse open https://example.com --cdp 9222
+browse open https://example.com --cdp ws://127.0.0.1:9222/devtools/browser/<id>
+```
+
+Use local mode for development, localhost, trusted sites, and fast iteration. Use `--auto-connect` only when the user explicitly wants to attach to an already-running debuggable Chrome session with existing cookies or login state; use `--local` when no debuggable Chrome is available. Use remote mode when Browserbase credentials are available and the site needs hosted browser infrastructure, Verified browser mode, CAPTCHA solving, proxies, or session persistence.
+
+`--local` requires Chrome or Chromium already installed on the machine. In containers, CI, and sandboxes with no browser installed, use `--remote` instead of `--local`. If `--local` fails with "No Chrome or Chromium found" and `BROWSERBASE_API_KEY` is set, switch to `--remote` — do not retry `--local`.
+
+For a Verified and/or proxied remote session, add `--verified` and/or `--proxies` to `--remote` — a single command that keeps the Browserbase session identity, so `browse status` and `browse doctor` report the session ID and live-view URL. `--verified` requires a Browserbase Scale plan. These flags only apply to `--remote` and are sticky for the session's lifetime, like `--headed`. Reach for `browse cloud sessions create` + `--cdp` only when you need session options `open` doesn't expose (region, keep-alive, contexts).
+
+Choose headed/headless and local/remote mode when starting a session. A running session keeps its mode: passing a conflicting flag such as `--headed` to an already-running headless session fails until you run `browse stop --session <name>` or target a different session.
+
+Use named sessions for any non-trivial work, especially when multiple agents or parallel tasks may run at once. Every browser command accepts `--session <name>` (or `-s <name>`); the `BROWSE_SESSION` env var sets the default, and commands without either share the `default` session.
+
+If `BROWSE_SESSION` is already set in the environment, every command already targets that session — do not pass `--session` or invent a new name. An explicit `--session <name>` always overrides `BROWSE_SESSION` for that command, so only pass it to deliberately target a different session.
+
+```bash
+browse open https://example.com --session research --local
+browse snapshot --session research
+```
+
+Remote browser and cloud API commands require:
+
+```bash
+export BROWSERBASE_API_KEY=...
+```
+
+## Browser Automation Workflow
+
+Start by opening the page, then inspect state, act, and verify.
+
+```bash
+browse open https://example.com --session research --local
+browse snapshot --session research
+browse click @0-5 --session research
+browse type "hello" --session research
+browse snapshot --session research
+browse stop --session research
+```
+
+Prefer `browse snapshot` over screenshots for most browser work. It is structured, fast, and returns refs like `@0-5` for reliable element interaction. Use screenshots when visual layout, images, or pixel-level state matter.
+
+Refs are refreshed on every snapshot. After clicks, form submits, navigation, or UI re-renders, take a new snapshot before using another ref.
+
+## Parallel Browser Work
+
+Use a different `--session` value for each independent browser task. Sessions isolate tabs, cookies, refs, and daemon state; parallel tasks that omit `--session` share the `default` session and overwrite each other's active page.
+
+```bash
+browse open https://example.com/search-a --session search-a --local
+browse open https://example.com/search-b --session search-b --local
+browse snapshot --session search-a
+browse snapshot --session search-b
+```
+
+When a task is complete, stop only that task's session:
+
+```bash
+browse stop --session search-a
+```
+
+## Core Browser Commands
+
+Navigation:
+
+```bash
+browse open <url>
+browse reload
+browse back
+browse forward
+browse wait load
+browse wait selector "#result"
+```
+
+Page state:
+
+```bash
+browse snapshot                            # formatted tree only
+browse snapshot --full                     # also include ref maps (xpathMap, urlMap)
+browse get url
+browse get title
+browse get text body
+browse get html "#main"
+browse get value "#email"
+browse get markdown body                   # page/element content as markdown
+browse eval "document.title"              # run JavaScript in the active page
+browse screenshot                         # saves screenshot-<timestamp>.png, prints { "saved": "<path>" }
+browse screenshot --path page.png         # choose the output path
+browse screenshot --base64                # legacy: print base64 JSON to stdout (avoid in agent loops)
+```
+
+Interaction:
+
+```bash
+browse click @0-5
+browse fill @0-8 "search query"
+browse type "text for the focused element"
+browse press Enter
+browse select "select[name=country]" "United States"
+browse upload @0-12 ./file.pdf
+browse highlight @0-5
+browse is visible "#modal"
+```
+
+Mouse and viewport:
+
+```bash
+browse mouse click 240 320
+browse mouse hover 240 320
+browse mouse drag 80 80 310 100
+browse mouse scroll 500 300 0 600
+browse viewport 1280 720
+browse cursor                             # show a visible cursor overlay
+```
+
+Tabs, network, and CDP:
+
+```bash
+browse tab list
+browse tab new https://example.com
+browse tab switch <target-id>
+browse tab close <target-id>              # refuses to close the last tab
+browse network on
+browse network off
+browse network path
+browse network clear
+browse cdp 9222 --pretty
+```
+
+Session management:
+
+```bash
+browse doctor
+browse doctor --json
+browse status
+browse stop
+browse stop --force
+```
+
+Use `browse doctor` before debugging a broken browser session. Use `browse doctor --json` when another agent or CI needs structured diagnostics.
+
+If a page command reports that no active page is available, inspect and recover the named session:
+
+```bash
+browse status --session research
+browse tab list --session research
+browse tab new https://example.com --session research
+browse open https://example.com --session research
+```
+
+## Cloud APIs
+
+Use `browse cloud` for Browserbase platform APIs:
+
+```bash
+browse cloud projects list
+browse cloud projects get <project-id>
+browse cloud projects usage <project-id>
+browse cloud sessions create
+browse cloud sessions create --proxies --verified
+browse cloud sessions list
+browse cloud sessions get <session-id>
+browse cloud sessions update <session-id>
+browse cloud sessions debug <session-id>
+browse cloud sessions logs <session-id>
+browse cloud sessions downloads get <session-id>
+browse cloud sessions uploads create <session-id> ./file.pdf
+browse cloud contexts create --name github
+browse cloud contexts add github <context-id>
+browse cloud contexts list
+browse cloud contexts get <context-id|name>
+browse cloud contexts update <context-id|name>
+browse cloud contexts delete <context-id|name>
+browse cloud extensions upload ./extension.zip
+browse cloud extensions get <extension-id>
+browse cloud extensions delete <extension-id>
+browse cloud fetch https://example.com
+browse cloud search "browser automation"
+```
+
+For remote sessions with context persistence:
+
+```bash
+browse cloud sessions create --context-id <context-id> --persist
+```
+
+Contexts persist cookies and local storage (logins) across sessions. Name a
+context once with `--name` to save a local alias, then reuse the name anywhere a
+context ID is accepted instead of memorizing the ID:
+
+```bash
+browse cloud contexts create --name github          # saves github -> ctx_...
+browse cloud contexts add github <context-id>        # name a context you already have
+browse cloud sessions create --context-id github --persist
+browse cloud contexts list                          # show saved names
+```
+
+Use `--verified` when the task needs Browserbase Verified browser mode. To drive a Verified/proxied session directly, prefer `browse open <url> --remote --verified --proxies` over create-then-attach — it keeps the session identity so `browse status`/`browse doctor` can report it. Use `browse cloud sessions create` for session options the driver flags don't cover (region, keep-alive, contexts, full `--stdin` body).
+
+Use `browse cloud fetch` when the user needs a simple HTTP fetch without browser interaction. It returns markdown-formatted page content by default; pass `--format raw` for the original response body or `--format json --schema <schema>` for structured extraction. Use `browse cloud search` when the user asks for web search results.
+
+## Browserbase Functions
+
+Use `browse functions` to create, develop, publish, and invoke Browserbase Functions:
+
+```bash
+browse functions init my-function
+browse functions dev index.ts
+browse functions publish index.ts
+browse functions publish index.ts --dry-run
+browse functions invoke <function-id> --params '{"url":"https://example.com"}'
+browse functions invoke --check-status <invocation-id>
+```
+
+Functions commands use `BROWSERBASE_API_KEY`. Generated projects import `defineFn` from `@browserbasehq/sdk-functions`.
+
+## Templates
+
+Use `browse templates` to discover and scaffold Browserbase starter templates:
+
+```bash
+browse templates list
+browse templates list --tag Python --source Browserbase
+browse templates find google-trends-keywords
+browse templates find amazon --json
+browse templates clone google-trends-keywords
+browse templates clone amazon-product-scraping --language python ./my-scraper
+browse templates clone dynamic-form-filling ./form-bot --language typescript
+```
+
+Use `browse templates find` before cloning when the exact slug is uncertain. Use `--language typescript` or `--language python` to choose the generated project runtime when a template supports both.
+
+## Skills
+
+Install or refresh this bundled CLI skill:
+
+```bash
+browse skills install
+```
+
+### Discovering Browse.sh Skills
+
+Browse.sh (https://browse.sh) is a catalog of site-specific browser automation skills. Each skill is scoped to one task on one website and identified by a `<domain>/<task>` slug. An installed skill encodes a proven strategy for that site — API endpoints, selectors, anti-bot handling — so it completes the task faster and more reliably than exploring the site from scratch.
+
+Search the catalog proactively when:
+
+- the user asks to complete a task on a specific website — search the domain before automating it by hand
+- the user asks for a task in a common category like flights, food delivery, reviews, recipes, tickets, jobs, or shopping — search the keyword
+- the user asks "is there a skill for X" or wants new capabilities
+
+```bash
+browse skills list                              # browse the catalog
+browse skills find <query>                      # search by slug, domain, title, description, category, alias, or tag
+browse skills add <domain>/<task>               # install an exact slug
+```
+
+### Search Strategy
+
+Search the domain first, then the task, then broaden:
+
+```bash
+browse skills find yelp.com                     # 1. exact domain
+browse skills find yelp                         # 2. site name
+browse skills find reviews                      # 3. task keyword
+browse skills find "restaurant reviews"         # 4. multi-word query
+browse skills find food --limit 5               # 5. category keyword, capped
+```
+
+- Querying an exact slug (`browse skills find yelp.com/extract-reviews-2ikb22`) prints a detail view with the full description and install command.
+- If a search returns nothing, try synonyms (`flights` vs `travel`, `food` vs `restaurants`) before concluding no skill exists.
+- Each result shows a recommended method — `api`, `fetch`, `browser`, or `hybrid` — indicating how the skill drives the site. Install counts signal which skills are proven.
+- Many slugs end in a generated suffix (`-2ikb22`), so never guess or construct them. Install only with an exact slug copied from `list` or `find` output: `browse skills add yelp.com/extract-reviews-2ikb22`. The installed skill becomes available to the agent as a regular skill; a new agent session may be needed to pick it up.
+
+### Output Formats
+
+Output is a table in a terminal and JSON when piped, so agents get structured JSON by default. Force a format with `--format table|json` or `--json`.
+
+```bash
+browse skills find food --format table --limit 10
+browse skills find food --json | jq -r '.skills[] | "\(.slug)\t\(.title)"'
+```
+
+JSON output includes every match with full descriptions and ignores `--limit`; `browse skills list --json` returns the entire catalog, which is large. Prefer `browse skills find <query>` to narrow first, or `--format table --limit <n>` for a compact view.
+
+## Best Practices
+
+1. Run the real command and inspect its output instead of guessing.
+2. Use `browse snapshot` before interacting so you have current refs.
+3. Re-run `browse snapshot` after navigation or DOM-changing actions because refs can change.
+4. Prefer refs from snapshots for clicks and uploads; use selectors or XPath when refs are unavailable.
+5. Use `--local` for localhost and repeatable development; use `--remote` for protected sites or Browserbase-specific behavior.
+6. Use a distinct `--session <name>` for each parallel or long-running task; commands without the flag share the `default` session.
+7. Use `--auto-connect` only when attaching to an existing debuggable local Chrome session is intended.
+8. Use `browse doctor` when session startup, browser discovery, CDP attach, or Browserbase auth looks wrong.
+9. Never retry a failing command unchanged. If the same command fails twice with the same error, stop — run `browse doctor --json`, then change approach (fix the key, switch `--local`/`--remote`, or `browse stop --force` and start fresh). Repeating an identical failing command will keep failing.
+10. Use `browse stop` (or `browse stop --session <name>`) when finished to clean up daemon state.
+11. For unfamiliar command details, run `browse <topic> --help` and follow the exact dash-case flags.
+
+## Troubleshooting
+
+- "No active page": run `browse status --session <name>`, then `browse open <url> --session <name>` or `browse tab new <url> --session <name>`; use `browse stop --force` if the daemon is stale.
+- Chrome not found: use `--remote` with Browserbase credentials, install Chrome, or attach with `--cdp`.
+- Action fails: run `browse snapshot` and use a visible ref from the current page state.
+- 401 Unauthorized on `open`, `get`, or other driver commands: a set `BROWSERBASE_API_KEY` makes `browse` default to remote mode. Fix the key at https://browserbase.com/settings, unset it, or pass `--local` to run a managed local browser (no key needed).
+- Same command fails twice with the same error: stop retrying — never retry a failing command unchanged. Init failures are cached for several seconds, so instant retries return identical errors. Run `browse doctor --json`, then change approach: fix the key, switch `--local`/`--remote`, or `browse stop --force` and start fresh.
+- Remote command fails: verify `BROWSERBASE_API_KEY` and inspect `browse cloud projects list`.
+- Session setup is unclear: run `browse doctor` or `browse doctor --json`.
+- Protected site blocks local mode: retry with `--remote`.
+- `browse skills find` returns nothing: broaden the query — bare domain, then site name, then a task keyword or synonym.
+- `browse skills add` fails on `npx`: install Node.js from https://nodejs.org, then rerun.
+- Newly added skill is not available: it installs for future sessions; list installed skills or start a new agent session.

The agent-creation log serialized the raw `integrations` array, and a live MCP `Client` is circular. It now logs a safe descriptor (URL strings kept, client instances summarized) so `agent({ integrations: [client] })` works.

+
+## What is Stagehand?
+
+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
+## Why Stagehand?
+
+Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language (and bridging the gap between the two) Stagehand is the natural choice for browser automations in production.
+
+1. **Choose when to write code vs. natural language**: use AI when you want to navigate unfamiliar pages, and use code when you know exactly what you want to do.
+
+2. **Go from AI-driven to repeatable workflows**: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.
+
+3. **Write once, run forever**: Stagehand's auto-caching combined with self-healing remembers previous actions, runs without LLM inference, and knows when to involve AI whenever the website changes and your automation breaks.
+
+## Getting Started
+
+Start with Stagehand with one line of code, or check out our [Quickstart Guide](https://docs.stagehand.dev/v3/first-steps/quickstart) for more information:
+
+```bash
+npx create-browser-app
+```
+
+## Example
+
+Here's how to build a sample browser automation with Stagehand:
+
+```typescript
+// Stagehand's CDP engine provides an optimized, low level interface to the browser built for automation
+const page = stagehand.context.pages()[0];
+await page.goto("https://github.com/browserbase");
+
+// Use act() to execute individual actions
+await stagehand.act("click on the stagehand repo");
+
+// Use agent() for multi-step tasks
+const agent = stagehand.agent();
+await agent.execute("Get to the latest PR");
+
+// Use extract() to get structured data from the page
+const { author, title } = await stagehand.extract(
+  "extract the author and title of the PR",
+  z.object({
+    author: z.string().describe("The username of the PR author"),
+    title: z.string().describe("The title of the PR"),
+  }),
+);
+```
+
+## Documentation
+
+Visit [docs.stagehand.dev](https://docs.stagehand.dev) to view the full documentation.
+
+### Build and Run from Source
+
+```bash
+git clone https://github.com/browserbase/stagehand.git
+cd stagehand
+pnpm install
+pnpm run build
+pnpm run example # run the blank script at ./examples/example.ts
+```
+
+Stagehand is best when you have an API key for an LLM provider and Browserbase credentials. To add these to your project, run:
+
+```bash
+cp .env.example .env
+nano .env # Edit the .env file to add API keys
+```
+
+### Installing from a branch
+
+To install Stagehand directly from a GitHub branch, install the core package subdirectory:
+
+```bash
+pnpm add "github:browserbase/stagehand#<branchName>&path:/packages/core"
+```
+
+Or set it in your project's `package.json`:
+
+```json
+"@browserbasehq/stagehand": "github:browserbase/stagehand#<branchName>&path:/packages/core"
+```
+

+      - choose the selectOptionFromDropdown method,

+      - set twoStep to false.
+    CASE 2: the element is NOT a 'select' element:
+      - do not attempt to directly choose the element from the dropdown. You will need to click to expand the dropdown first. You will achieve this by following these instructions:
+        - choose the node that most closely corresponds to the given instruction EVEN if it is a 'StaticText' element, or otherwise does not appear to be interactable.  
+        - choose the 'click' method

+  If the action is completely unrelated to a potential action to be taken on the page, or no matching element exists, set \`action\` to null. Do not fabricate or guess an element.
+  ONLY return one action. If multiple actions are relevant, return the most relevant one.
+  If the user is asking to scroll to a position on the page, e.g., 'halfway' or 0.75, etc, you must return the argument formatted as the correct percentage, e.g., '50%' or '75%', etc.
+  If the user is asking to scroll to the next chunk/previous chunk, choose the nextChunk/prevChunk method. No arguments are required here.
+  If the action implies a key press, e.g., 'press enter', 'press a', 'press space', etc., always choose the press method with the appropriate key as argument — e.g. 'a', 'Enter', 'Space'. Do not choose a click action on an on-screen keyboard. Capitalize the first character like 'Enter', 'Tab', 'Escape' only for special keys.

+
+# Your current goal

+
+# CRITICAL: You MUST use the provided tools to take actions. Do not just describe what you want to do - actually call the appropriate tools.
+
+# Available tools and when to use them:
+- \`act\`: Use this to interact with the page (click, type, navigate, etc.)
+- \`extract\`: Use this to get information from the page
+- \`goto\`: Use this to navigate to a specific URL
+- \`wait\`: Use this to wait for a period of time
+- \`navback\`: Use this to go back to the previous page
+- \`refresh\`: Use this to refresh the current page
+- \`close\`: Use this ONLY when the task is complete or cannot be achieved
+- External tools: Use any additional tools (like search tools) as needed for your goal
+
+# Important guidelines
+1. ALWAYS use tools - never just provide text responses about what you plan to do
+2. Break down complex actions into individual atomic steps
+3. For \`act\` commands, use only one action at a time, such as:
+   - Single click on a specific element
+   - Type into a single input field
+   - Select a single option
+4. Avoid combining multiple actions in one instruction
+5. If multiple actions are needed, they should be separate steps
+6. Only use \`close\` when the task is genuinely complete or impossible to achieve`,

+* The screen's resolution is ${width}x${height}.
+* Whenever you intend to move the cursor to click on an element like an icon, you should consult a screenshot to determine the coordinates of the element before moving the cursor.
+* If you tried clicking on a program or link but it failed to load, even after waiting, try adjusting your cursor position so that the tip of the cursor visually falls on the element that you want to click.
+* Make sure to click any buttons, links, icons, etc with the cursor tip in the center of the element. Don't click boxes on their edges unless asked.
+* When a separate scrollable container prominently overlays the webpage, if you want to scroll within it, you typically need to mouse_move() over it first and then scroll().
+* If a popup window appears that you want to close, if left_click() on the 'X' or close button doesn't work, try key(keys=['Escape']) to close it.
+* On some search bars, when you type(), you may need to press_enter=False and instead separately call left_click() on the search button to submit the search query. This is especially true of search bars that have auto-suggest popups for e.g. locations
+* For calendar widgets, you usually need to left_click() on arrows to move between months and left_click() on dates to select them; type() is not typically used to input dates there.`;

+    - For URL fields, use format: "url"
+    
+    EXAMPLES:
+    1. Extract a single value:
+       instruction: "extract the product price"
+       schema: { type: "object", properties: { price: { type: "number" } } }
+    
+    2. Extract multiple fields:
+       instruction: "extract product name and price"
+       schema: { type: "object", properties: { name: { type: "string" }, price: { type: "number" } } }
+    
+    3. Extract arrays:
+       instruction: "extract all product names and prices"
+       schema: { type: "object", properties: { products: { type: "array", items: { type: "object", properties: { name: { type: "string" }, price: { type: "number" } } } } } }
+    
+    4. Extract a URL:
+       instruction: "extract the link"
+       schema: { type: "object", properties: { url: { type: "string", format: "url" } } }`,
+    inputSchema: z.object({

+ * Stagehand V3 Logging
+ *
+ * Design goals:
+ * - Support concurrent V3 instances with independent logger configuration
+ * - Each V3 instance has its own StagehandLogger (handles usePino, verbose, externalLogger)
+ * - Provide AsyncLocalStorage-based routing for backward compatibility with handler code
+ * - Prevent cross-talk between concurrent instances
+ *
+ * How it works:
+ * - Each V3 instance creates a StagehandLogger in its constructor (per-instance config)
+ * - bindInstanceLogger()/unbindInstanceLogger(): registers logger callback per instance ID
+ * - withInstanceLogContext(): establishes AsyncLocalStorage context for an async operation
+ * - v3Logger(): routes logs using AsyncLocalStorage with console fallback
+ *
+ * ⚠️ CONTEXT LOSS SCENARIOS:
+ * 1. setTimeout/setInterval callbacks lose context (runs outside AsyncLocalStorage scope)
+ * 2. Event emitters (EventEmitter.on) lose context (callback invoked outside scope)
+ * 3. Fire-and-forget promises (void promise) lose context if they don't complete synchronously
+ * 4. Third-party library callbacks may lose context depending on implementation
+ *
+ * WORKAROUND for context loss:
+ * - Use explicit logger parameter instead of v3Logger()
+ * - Wrap callback in withInstanceLogContext() manually
+ * - Or let logs fall back to console (acceptable for edge cases)

+ * FrameRegistry
+ *
+ * Purpose:
+ * A single, authoritative source of truth for **both**:
+ *   1) Frame topology (parent/children, current main/root id, last-seen CDP `Frame`)
+ *   2) Frame → Session ownership (which CDP session owns a given frameId)
+ *   3) Optional iframe-owner metadata (backendNodeId of the <iframe> element in the parent doc)
+ *
+ *
+ * Model:
+ *  - This class is **CDP-agnostic**; it stores **sessionId strings** (not session objects).
+ *  - Context bridges (wiring Target/Page events) must call the mutators below (onAttached,
+ *    onNavigated, onDetached, adoptChildSession, seedFromFrameTree, setOwnerBackendNodeId).
+ *  - Consumers ask read APIs (getOwnerSessionId, getParent, asProtocolFrameTree, listAll, …)
+ *    and never probe ownership at run time.

+ * Response

+ * abstraction is consumed by navigation routines (e.g. `Page.goto`) so callers
+ * can synchronously inspect status codes, lazily fetch body text, or await the
+ * network layer finishing the request. The implementation is built directly on
+ * Chrome DevTools Protocol primitives – it holds the originating `requestId`
+ * so it can request payloads via `Network.getResponseBody`, and it listens for
+ * `responseReceivedExtraInfo`, `loadingFinished`, and `loadingFailed` events to
+ * hydrate the richer header view and resolve callers waiting on completion.

+ * Responsibilities:
+ * - Bootstraps Chrome or Browserbase, ensures a working CDP WebSocket, and builds a `V3Context`.
+ * - Manages lifecycle: init, context access, cleanup.
+ * - Bridges external page objects (Playwright/Puppeteer) into internal frameIds for handlers.
+ * - Provides a stable API surface for downstream code regardless of runtime environment.

+ * it without a runtime parse step.
+ *
+ * Two-level hierarchy: 8 top-level categories, each with numbered
+ * sub-categories (e.g., "2.3 Output fabrication"). Used by:
+ *   - Failure analysis (Step 9a) — categories 1–6.
+ *   - Task classification (Steps 9b + 10) — categories 7 (ambiguity) and 8 (invalid).
+ *
+ * Calibration: not every imperfection is a failure. Only flag issues that
+ * materially affected task completion, correctness, or user trust.

+
+**Rubric Criteria:**
+$rubric_criteria
+
+**Evidence Points in This Batch:**
+$evidence_manifest
+
+The evidence is presented to you in order: each image / text block in this message corresponds to one entry in the manifest above, identified by its \`evidence_idx\`.
+
+**Your Task:**
+For EACH evidence point in the batch, assign a relevance score from 0–10 against EACH criterion.
+
+**Scoring Guidelines:**
+- **10**: Evidence directly shows critical proof for this criterion (e.g., shows the exact item, cart contents, confirmation page, the filled form field).
+- **7-9**: Evidence shows important contextual information for this criterion (search results, applied filters, navigation state).
+- **4-6**: Evidence shows partial / related information for this criterion.
+- **1-3**: Evidence shows minimal relevance to this criterion.
+- **0**: Evidence is completely irrelevant to this criterion.
+
+**Important:**
+- An evidence point can be highly relevant to multiple criteria.
+- Focus on what is VISIBLE in the screenshot or PRESENT in the text snippet, not what the agent claimed.
+- Text-form evidence (e.g., accessibility tree snippets, agent text, JSON tool outputs) is especially relevant for criteria asking "is this field filled with X?", "does the page contain Y?", or "did the tool return X?" — score it accordingly.
+
+**Output Format:**
+Output a JSON object with an \`items\` list. One entry per evidence point in the batch:
+
+{{
+  "items": [
+    {{
+      "evidence_idx": 0,
+      "scores": [

+        {{ "criterion_idx": 1, "score": 2 }}
+      ]
+    }},
+    ...one entry per evidence point...
+  ]
+}}
+
+You MUST include an entry for every \`evidence_idx\` listed in the manifest, and every criterion_idx in each \`scores\` list.
+
+DO NOT OUTPUT ANYTHING OTHER THAN JSON.

+When task validity is requested, you must populate \`task_validity\` with the booleans \`is_ambiguous\` / \`is_invalid\` and, when each is true, a single one-line free-form reason in \`ambiguity_reason\` / \`invalid_reason\` (e.g., "Requested dates are in the past relative to the current date"). Leave the reason field empty when the corresponding flag is false.
+
+---
+
+**Core Evaluation Principles** (these OVERRIDE the criterion descriptions when they conflict):
+
+1. **Best Effort Evaluation.** The agent should be evaluated on helpfulness and effort within constraints it cannot control.
+
+2. **Uncontrollable Blockers** (award full credit when these prevent task completion): platform issues (site down, CAPTCHA, login walls), entity non-existence, availability constraints (out of stock, sold out), platform limitations. If screenshots CONFIRM the blocker, award full credit even for downstream dependent criteria.
+
+3. **Controllable Failures** (penalize): wrong selections when correct options are available, poor execution (not using filters, not attempting specified platforms), hallucinations (claiming success without evidence), insufficient effort.
+
+4. **Tasks with Explicit Constraints.** Distinguish "searched for the constraint" from "found results that actually satisfy it". If the hard constraint is NOT met in the evidence, award only minimal partial credit for the search effort.
+
+5. **Ambiguous Wording — Don't Penalize for One Valid Interpretation.** If the task has multiple defensible readings, the agent picking one is fine.
+
+6. **Cascading Dependencies:**
+   - Scenario A: Blocker is uncontrollable → award full credit for downstream criteria that couldn't be attempted.
+   - Scenario B: Blocker is a controllable error → cascade partial/zero credit downstream.
+   - Scenario C: Don't re-penalize for the same deviation across multiple criteria.
+   - Scenario D: Shared platform blockers across sibling sub-tasks → award full credit for all affected siblings.
+
+7. **Conditional Criteria.** Some criteria have a "condition" field. Only score them when the condition is met; otherwise mark the criterion as not applicable (give it max_points so it doesn't drag down the process score).
+
+8. **Distinguish nitpicks from critical errors:**
+   - Only nitpicks → 75–100% of max
+   - Correct approach, wrong final answer → 40–80%
+   - Critical error → penalize per severity
+   - Mix of nitpicks + a critical error → score based on the critical error
+
+**Outcome Judgment:**
+
+\`output_success\` is your independent binary verdict on whether the agent completed the task. It is informed by the per-criterion scores but is not a function of them — a task can have high process score and still fail (right approach, wrong final answer) or have lower process score and still succeed (the answer is right, intermediate steps were inelegant).
+
+**Findings:** Surface actionable patterns: failed tool usage, agent-strategy issues, rubric quality problems, capture gaps. Each finding gets a category, severity, description, and (optional) related steps + suggested action. Keep findings sparse and load-bearing.

+When task validity is requested, populate \`task_validity\` with the booleans \`is_ambiguous\` / \`is_invalid\` and, when each is true, a single one-line free-form reason in \`ambiguity_reason\` / \`invalid_reason\` (e.g., "Requested dates are in the past relative to the current date"). Leave the reason field empty when the corresponding flag is false.
+
+---
+
+**Outcome judgment:**
+\`output_success\` is your independent binary verdict on whether the agent completed the task. It is informed by the per-criterion scores but is not a function of them — a task can have high process score and still fail (right approach, wrong final answer), or have lower process score and still succeed.
+
+Apply these rules when making the outcome verdict:
+
+1. **Judge the delivered result, not the route.** If the final answer satisfies the user's requested deliverable and the trajectory does not contradict it, mark success even if the agent used an inefficient path, clicked around after finding the answer, or used a slightly different but reasonable search control. Do not fail solely because the process was imperfect.
+
+2. **Use the simulated trajectory as truth.** Do not use outside/current-world knowledge to override what the saved browser state shows. If search results, page text, URLs, or screenshots in the trajectory support a concrete answer, judge against that evidence even if the real web may differ. Do not introduce an alternate "correct" answer from your own knowledge unless that alternate answer is visible in the supplied trajectory evidence.
+
+3. **Treat attached screenshots as partial evidence.** Screenshots may be sampled from a longer trajectory. If the final answer is concrete and the action history shows the agent reached a relevant source (page, list, chart, search result, product page, map result), assume the answer may have been extracted from that source unless the attached screenshots or action history directly contradict it. Do not call a concrete answer fabricated merely because the exact supporting text is absent from the sampled screenshots.
+
+4. **Require the actual deliverable.** The final answer is the user-visible deliverable. For tasks asking to find, show, get, browse, list, summarize, report, compare, or provide values/content, the final answer must contain the requested content or a direct correct link to the requested document/page. Merely saying the agent "found", "extracted", "provided", "displayed", "retrieved", or "located" the information is not enough, even if the browser reached the right page. The selected trajectory evidence is only context; it cannot fill in missing values, lists, links, or summaries that are absent from the final answer. Only purely navigational tasks phrased as opening a page can succeed from navigation alone.
+
+5. **Report/document tasks need the report/document.** If the task asks to get, open, retrieve, download, or provide a report/document/page, the final answer must include a direct correct URL, the opened document/page itself must be the final browser state, or the final answer must include the requested document content. Merely naming the document title is not enough unless the user only asked for the title/name.
+
+6. **Do not invent equivalence.** If the final answer gives a URL, document, article id, product, entity, date, or value that differs from what the trajectory visibly reached, do not assume an unseen redirect, canonicalization, or equivalence. Treat the mismatch as a contradiction unless the supplied trajectory evidence itself shows they are equivalent.
+
+7. **Hard constraints still matter.** If the latest relevant attached screenshot, selected trajectory evidence, or action-history URL clearly shows that an explicit constraint was not met (for example wrong sort/filter/date/class, permanently closed location reported as active, visible product/list item outside the requested color/size/status, wrong URL/article id, or wrong entity), that is a critical issue.
+
+8. **Dynamic sources can disagree.** Search results, charts, rankings, prices, and listings can differ across pages or update times in the saved trajectory. If the final answer is concrete and matches at least one relevant trajectory source, do not fail solely because another relevant source in the trajectory shows a different dynamic value, unless the final answer clearly used the contradicted source or the task required that exact source.
+
+9. **Shopping/search constraints may be source-level.** For product-search tasks, a search query, filter, result page, or product title/snippet can satisfy a descriptive constraint such as "hypoallergenic" when the final answer provides concrete candidate products and no supplied evidence directly contradicts the constraint. Do not fail solely because a later product page does not repeat every search constraint as a formal specification.
+
+10. **Separate nitpicks from critical issues.** Minor wording, harmless method choices, unsupported extra details that are not part of the requested deliverable, caveats about imperfect verification, or small presentation differences should not flip a successful answer to failure when the final answer still provides concrete requested content and the trajectory does not directly contradict it. Wrong requested entities, unsupported fabricated requested facts, active-vs-closed mistakes, wrong sort/filter results, wrong dates/classes, and missing requested content are critical.
+
+Use this decision order:
+
+- First ask whether the final answer contains the requested user-facing artifact: values, list items, summary, comparison, report link, product candidates, or page/document URL. If it only narrates that the artifact was found/extracted/provided, mark failure.
+- Then check for direct contradictions in the supplied trajectory evidence. Contradictions must come from the provided action history, URLs, screenshots, or final answer, not from outside knowledge.
+- If the final answer is concrete, the trajectory reached a relevant source, and the supplied evidence does not directly contradict the final answer, mark success.

+**Findings:** Surface actionable patterns: failed tool usage, agent-strategy issues, rubric quality problems, capture gaps. Each finding gets a category, severity, description, and (optional) related steps + suggested action. Keep findings sparse and load-bearing.

+export const RUBRIC_GENERATION_PROMPT = `Task: $task_id$init_url_context
+    You are an expert tasked with analyzing a given task to identify the key points and sub-goals explicitly stated in the task description to create a rubric for evaluation.
+
+    **Objective**: Carefully analyze the task and extract the critical elements/goals/success criteria **explicitly** mentioned in the task for achieving its goal. Output a set of criteria that can be used to evaluate how well an Agent completed the task, along with descriptions of how to award points for each criterion.
+
+    **Critical Point Definition**
+    NOTE: The rubric should **not** contain criteria that violate a "Critical Point" or penalize scores for not crossing a Critical Point. A Critical Point, e.g. involving 'Checkout', 'Book', 'Purchase', 'Call', 'Email', etc, is a binding transaction/agreement that would require the user's permission to use personal or sensitive information (name, email, credit card, address, email, resume, etc) in order to complete a transaction (purchase, reservation, etc) or enter into a communication that a human would be expected to do (e.g. call or email).
+    - For example, when purchasing a product, it is acceptable have a criterion to "Add to Cart", or select the desired timeslot to book a reservation, but it **NOT** acceptable to propose a criteria to actually complete the checkout process (requiring entering the user's name, address, credit card, or sign into their account, etc unless specified in the Task). Stopping on the "Customer Details" is generally acceptable. If some stores/restaurants require a location before showing the product or reservation, the agent can enter a location (e.g. city) if known, but should not enter any personal information (e.g. name, email, phone number, etc).
+    - For example, if the task is to "call a restaurant to make a reservation," the success criteria should not say to make the call but rather to **find** the phone number.
+    - Similarly, if the task is to "order new size 12 running shoes" the criteria should not say place the order but instead find the right shoes and add them to the cart.
+    - If the task contains user information like name/email/address/etc, make a criterion stating that **other** user information not provided in the task is not "made up", and only what is given is reflected accurately in e.g. the checkout process.
+
+    **Controllable vs. Uncontrollable Factors** (Critical for Fair Evaluation):
+    When creating rubric criteria, distinguish between factors within and outside the agent's control. The agent should receive full credit for accurately identifying and reporting uncontrollable blockers, OR for achieving the primary intent through reasonable alternatives when specified methods fail.
+
+    **UNCONTROLLABLE FACTORS** (Full credit for identifying/reporting these):
+    1. **Platform/Infrastructure Issues**: Website down, blocked by CAPTCHA, login walls (without credentials), server errors, missing functionality
+    2. **Entity Non-Existence**: Restaurant/business closed or doesn't exist, product discontinued, service no longer available, person/entity not in directory
+    3. **Availability/Inventory Constraints**: No reservations/flights on requested date, out of stock, sold out, seasonal unavailability
+    4. **Search Result Limitations**: No exact match exists, requested attribute combination impossible, empty result sets
+    5. **Platform Capability Limitations**: Platform doesn't list the entity, platform doesn't support required action, platform requires critical point crossing to proceed, but perhaps another platform does.
+    6. **Information Accuracy Issues Beyond Agent Control**: Third-party data outdated, price/availability changed during browsing, conflicting information across sources
+
+    **CONTROLLABLE FACTORS** (Should be penalized):
+    1. **Primary Intent Violations**: Wrong entity (restaurant/product name), wrong critical attributes (date/location) when correct ones available, ignoring explicit constraints when alternatives exist
+    2. **Navigation and Search Errors**: Not attempting specified platform when accessible, poor search strategy, not using available filters
+    3. **Execution Errors**: Incorrect data entry, skipping required steps, wrong selections from available options
+    4. **Communication Failures**: Not reporting blockers encountered, hallucinations (claiming success without evidence), incomplete reporting, false unavailability claims
+    5. **Insufficient Effort**: Premature abandonment after single attempt, not trying alternatives when appropriate, immediately using alternatives without attempting specified approach
+    6. **Misunderstanding Task Requirements**: Crossing critical points unnecessarily, adding unrequested steps, ignoring task scope
+
+    **Interpret Task Verbs Charitably (Do NOT Over-Literalize)**:
+    Many tasks use casual, everyday language. Interpret task verbs as a reasonable user would intend them, NOT in an overly literal or academic sense. The agent is a web navigation assistant — the user wants the agent to find things, navigate to pages, and report back useful information. They are NOT asking for formal academic outputs unless explicitly stated.
+
+    Common examples of verbs and similar subjective terms that should be interpreted charitably:
+    - **"Locate"**, **"find"**, **"pull up"**, **"look up"**, **"check"**: Navigate to the relevant page/content and report the key information. Do NOT require the agent to output a URL unless explicitly asked.
+    - **"Review"**, **"read"**, **"look at"**, **"go through"**: Navigate to the content and provide a reasonable summary or overview of what was found. Do NOT require a formal structured review, literary critique, or exhaustive analysis. A brief summary of the key points visible on the page is sufficient.
+    - **"Show me"**, **"get me"**: Find and present the relevant information. The user wants to see the content, not a URL.
+    - **"Research"**, **"explore"**: Browse relevant sources and report findings. Do NOT require academic-level depth unless explicitly stated.
+
+    When creating rubric criteria for these or similar kinds of subjective verbs, the success criteria should focus on whether the agent **found the right content and reported useful information**, NOT on the depth, format, or presentation style of the output.
+
+    **SubGoal Definition**:
+    A **subgoal** is a critical element, condition, or step **explicitly** mentioned in the task description required for success.
+    - Do not infer or add any unstated subgoals or criteria, e.g. if the task is "what standard length of vinyl outside corner trim does HomeDepot sell?", do NOT add a criterion requiring the URL of the product, because it was not asked.
+    - **Intermediate Discovery vs. Required Output**: Criteria may verify that the agent *found, viewed, or interacted with* the correct intermediate results during navigation (e.g., "searched for and reviewed relevant Azure courses on Coursera"), but should NOT require the agent to *output or list* those intermediate results unless the task explicitly asks for them. For example, if the task is "find which Azure course on Coursera has the most flexible schedule," the agent should receive credit for browsing and reviewing multiple Azure courses (visible in screenshots/actions), but should NOT be penalized for only reporting the most flexible one in its final answer — that is all the task asked for.
+    - Do not make redundant or overlapping criteria (e.g. for the task "book a flight on air asia", do NOT make separate criteria for "access airasia.com" and "ensure AirAsia as the booking platform" since they are redundant)
+    - Separate **what** the subgoals are from **how** to evaluate them
+
+    **CRITICAL: Handling Conditional Criteria**:
+
+    Some tasks contain **conditional requirements** that only apply when specific conditions are met. These must be modeled explicitly using a "condition" field.
+
+    **When to create a conditional criterion**:
+    - Task contains phrases like "if...", "let me know if...", "report any issues", "in case of unavailability"
+    - The requirement only applies when a specific trigger condition occurs
+    - Examples:
+      * "Add flour to cart. Let me know if there are availability issues." → Reporting is conditional on encountering issues
+      * "Book a direct flight, or if none available, book a one-stop flight." → One-stop criterion is conditional on no direct flights existing
+      * "Buy organic blueberries, or if unavailable, buy non-organic." → Non-organic criterion is conditional on organic being unavailable
+
+    **How to structure conditional criteria**:
+    1. Add a "condition" field (string) that describes the triggering condition
+    2. In the "description" field, explain both the condition AND how to score if condition is met
+    3. Make it clear that points are ONLY counted if the condition is met
+
+    **Schema for conditional criteria**:
+    {{
+        "criterion": "Brief name of what's being evaluated",
+        "condition": "Clear description of when this criterion applies (e.g., 'Only applies if organic blueberries are unavailable')",
+        "task_span": "Verbatim substring of the original task that THIS criterion is evaluating (e.g., 'organic blueberries')",
+        "description": "What to evaluate and how to score IF the condition is met. Full credit for..., partial credit for...",
+        "max_points": N,
+        "justification": "",
+        "earned_points": ""
+    }}
+
+    **Schema for non-conditional criteria** (most criteria):
+    {{
+        "criterion": "Brief name of what's being evaluated",
+        "task_span": "Verbatim substring of the original task that THIS criterion is evaluating (e.g., 'add flour to cart')",
+        "description": "What to evaluate and how to score. Full credit for..., partial credit for...",
+        "max_points": N,
+        "justification": "",
+        "earned_points": ""
+    }}
+    (Note: No "condition" field means the criterion always applies)
+
+    **task_span — ANTI-HALLUCINATION ANCHOR (REQUIRED)**:
+    Every criterion **must** include a "task_span" field whose value is a **verbatim substring** of the original task description (the text after "Task:" above). This is the literal phrase from the task that justifies including this criterion.
+    - If you cannot copy a contiguous substring of the task that justifies the criterion, **the criterion does not belong in the rubric** — the task did not ask for it. Drop it.
+    - Substrings shorter than 3 words are not enough — pick a span that makes the connection unambiguous.
+    - Do NOT paraphrase, summarize, or normalize the span. Copy it character-for-character so a downstream check can verify it is a substring of the task.
+    - For setup/platform criteria implied by the task's specified platform, copy the platform name verbatim (e.g., task_span: "drugssquare.com").
+    - For Critical Point boundary criteria, you may use the special token "<critical-point>" — this is the ONE permitted non-substring value, since the Critical Point rule is supplied by these instructions, not the task text.
+
+    **Important**: Do NOT create conditional criteria for requirements that are implicitly satisfied by successful task completion.
+    - Example: "Add flour to cart. Let me know if unavailable."
+      * WRONG: Separate conditional criterion "Report unavailability (condition: flour unavailable)"
+      * RIGHT: Single criterion "Add flour to cart" with description: "Full credit if flour added to cart successfully OR if flour is unavailable and agent reports this"
+    - Why? Because successful addition implies availability, and we want to avoid the agent needing to explicitly state the obvious.
+
+    **When TO create a conditional criterion**:
+    - When the task explicitly requests an alternative action or fallback behavior
+    - When you have mutually exclusive options (only one should be counted based on circumstances)
+
+    **IMPORTANT: Mutually Exclusive Conditionals**:
+    When a task has mutually exclusive alternatives (only one should apply), make ALL alternatives conditional with opposite conditions. This ensures only ONE is counted.
+
+    Common pattern example: "do X, or if X unavailable, do Y"
+    - Make BOTH X and Y conditional with opposite conditions
+    - Only the applicable one will be counted during scoring
+
+    Concrete example: "Buy organic blueberries, or if unavailable, buy non-organic"
+    - Criterion 1: "Buy organic blueberries" (condition: "Only applies if organic blueberries are available")
+    - Criterion 2: "Buy non-organic blueberries" (condition: "Only applies if organic blueberries are unavailable")
+    - During scoring: Only ONE will have is_condition_met=true, so only ONE is counted
+
+    **Examples**:
+
+    Example 1: "Add flour and vegetable oil to cart at Ralphs. Let me know if there are availability issues."
+    - Criterion 1: Add flour to cart [no condition field] - Description includes: "Full credit if flour added OR if unavailable and agent reports this"
+    - Criterion 2: Add vegetable oil to cart [no condition field] - Description includes: "Full credit if oil added OR if unavailable and agent reports this"
+    - Do NOT create separate conditional criteria for reporting, since successful addition implies availability
+
+    Example 2: "Buy organic blueberries at Whole Foods. If they don't have organic, buy non-organic ones. If they don't have any blueberries at all, let me know."
+    - Criterion 1: Buy organic blueberries [condition: "Only applies if organic blueberries are available"]
+    - Criterion 2: Buy non-organic blueberries [condition: "Only applies if organic blueberries are unavailable but non-organic are available"]
+    - Criterion 3: Report complete unavailability [condition: "Only applies if neither organic nor non-organic blueberries are available"]
+    - Note: Exactly ONE of these three criteria will have is_condition_met=true during scoring
+
+    **Ensure Criterion Disjointness (Avoid Double-Penalty Structures)**:
+    Make criteria as disjoint and non-overlapping as possible to avoid penalizing the same mistake multiple times.
+
+    **Key Principle**: If criterion A penalizes for not using platform/method X, then other criteria should evaluate task completion aspects (finding entities, making selections, progressing workflows) **independently** of whether platform/method X was used.
+
+    **Pattern to AVOID** (Double-penalty):
+    - Criterion 1: "Identify a Mexican restaurant on gayot.com"
+    - Criterion 2: "Reach reservation interface on gayot.com"
+    - Problem: Both penalize for not using gayot.com → agent loses points twice for same mistake
+
+    **Pattern to FOLLOW** (Disjoint):
+    - Criterion 1: "Attempt gayot.com as the specified platform" (evaluates platform usage)
+    - Criterion 2: "Identify a Mexican restaurant in Chicago's Northside" (evaluates entity identification, independent of platform)
+    - Criterion 3: "Reach a reservation booking interface for the restaurant" (evaluates workflow progress, independent of platform)
+    - Result: If gayot.com fails, agent only loses points on Criterion 1, not on 2 and 3
+
+    **Do Not Create Duplicate Criteria**:
+    Do NOT create multiple criteria that penalize the same mistake. Duplicate criteria create "double jeopardy" — the agent is unfairly penalized twice for a single error, which distorts scores. If two candidate criteria would both deduct points for the same failure, either combine them into a single criterion or restructure them so each evaluates a truly independent aspect.
+
+    **Examples of duplicates to avoid**:
+    - "Progress booking flow up to Critical Point" + "Respect Critical Point and avoid personal info"
+      → Instead, create ONE criterion: "Progress booking flow up to (but not beyond) the Critical Point, stopping before entering personal/payment information"
+    - "Add product to cart" + "Do not complete checkout"
+      → Instead, create ONE criterion: "Add product to cart and stop before entering personal/payment details"
+    - "Add the liquid ingredients to the Target cart" + "Ensure only liquid ingredients are added to the cart"
+      → Instead, create ONE criterion: "Add only the liquid ingredients to the Target cart" — the action and the constraint evaluate the same thing: whether the correct items (and only the correct items) were added. Adding a wrong item should be penalized once, not twice.
+    - "Identify suitable online purchase options for each listed spice/seasoning" + "Limit purchasing scope to spices/seasonings only"
+      → Instead, create ONE criterion: "Identify suitable online purchase options for only the listed spices/seasonings" — the scope constraint is already implicit in the action: if the agent correctly identifies options for each listed spice, it has necessarily limited scope to spices.
+
+    **Test for duplication**: Ask yourself: "If the agent makes mistake X, would it lose points in multiple criteria?" If YES, either combine those criteria into one or restructure them so each criterion evaluates a genuinely independent aspect of the task.
+
+    **Decompose List-Style Tasks into Per-Item Criteria**:
+    When a task contains a "laundry list" of items to perform the same action on (e.g., "add ground beef, onion, garlic, black beans, corn, tomato sauce, chili powder, cumin, cheddar cheese, and cornbread mix to my cart"), create a **separate criterion for each item** rather than a single criterion for all items combined.
+
+    **When to apply this rule**:
+    - The task lists 3 or more items/entities that all require the same type of action (e.g., add to cart, search for, book, find, look up, etc.)
+    - The items are independently actionable (success/failure on one item does not inherently depend on another)
+
+    **Why**: Each item may have independent failure modes (out of stock, not found, wrong product selected, different availability). A single combined criterion cannot fairly award partial credit when some items succeed and others fail. Separate criteria allow precise, per-item scoring.
+
+    **How**: Create one criterion per item, each with its own max_points and description including item-specific partial credit guidance (e.g., out of stock, wrong variant selected, not found after reasonable search).
+
+    **Example**: Task: "Add ground beef, onion, garlic, black beans, and corn to my cart on Stop & Shop"
+    - WRONG: Single criterion "Add all grocery items to cart" [10 points]
+    - RIGHT: Separate criteria:
+      * "Add ground beef to cart" [2 points] — Full credit if added, or if unavailable and agent reports this. Partial credit for wrong cut/variant when correct one is available.
+      * "Add onion to cart" [2 points] — Full credit if added, or if unavailable and agent reports this.
+      * "Add garlic to cart" [2 points] — Full credit if added, or if unavailable and agent reports this.
+      * "Add black beans to cart" [2 points] — Full credit if added, or if unavailable and agent reports this.
+      * "Add corn to cart" [2 points] — Full credit if added, or if unavailable and agent reports this.
+
+    **Note**: You may still have additional criteria for platform access (e.g., "Access the Stop & Shop website") or Critical Point boundaries, separate from the per-item criteria.
+
+    **Partial Credit Guidance** (to be incorporated into the "description" field of each criterion):
+    Each criterion's "description" field must specify how to handle both successful completion AND common failure modes caused by external factors. Use the framework below:
+
+    **1. Primary Intent vs. Secondary Constraints**:
+    - **Primary intent**: The core objective that defines task success (e.g., "book reservation at Restaurant X on date Z")
+    - **Secondary constraints**: Preferred methods/platforms (e.g., "using platform Y")
+    - Award **FULL credit** if primary intent is achieved through reasonable alternatives when secondary constraints are impossible due to uncontrollable factors
+    - Award **PARTIAL credit** if secondary constraints are ignored without attempting them first, but primary intent is still achieved
+    - Award **NO credit** if primary intent is violated (e.g., booking wrong restaurant name or wrong date when correct ones are available)
+
+    **2. Entity Non-Existence Scenarios**:
+    - If a specified entity (restaurant, product, business, service) no longer exists or cannot be found after reasonable search, award **FULL credit** for clearly reporting this finding
+    - If an entity doesn't exist, award **FULL credit** for either: (a) reporting non-existence OR (b) identifying a reasonable alternative that matches the primary intent
+    - Examples: Restaurant closed permanently, product discontinued, airline no longer operates that route, person not in directory
+
+    **3. Availability and Inventory Constraints**:
+    - For time-sensitive requests (dates, times, reservation slots), award **FULL credit** for accurately reporting unavailability when the requested option genuinely doesn't exist
+    - Award **FULL credit** for either: (a) clearly stating unavailability OR (b) selecting the best available alternative that matches primary intent
+    - Examples: No direct flights on requested date, restaurant fully booked, product out of stock, hotel no vacancy
+
+    **4. Platform Capability Limitations**:
+    - If a specified platform cannot support the required action (e.g., platform doesn't list the entity, platform blocks access, platform requires critical point crossing), award **FULL credit** for either: (a) reporting this limitation OR (b) achieving the goal through an alternative platform
+    - Do NOT penalize for using alternative platforms when the specified platform is genuinely incapable or inaccessible
+    - Example: Platform Y doesn't have Restaurant X listed → full credit for booking Restaurant X on Platform Z instead
+
+    **5. Search Results and Filtering Constraints**:
+    - When a task involves multiple filtering criteria but no result satisfies them all, award **FULL credit** if the agent: (a) identifies the best available option matching the **primary intent**, OR (b) states that no exact match exists, OR (c) both
+    - For subjective tasks (e.g., "find the best new sushi restaurant"), award **FULL credit** for consulting authoritative sources and making reasonable selections
+    - Example: Task requests "100% cotton Power Rangers hoodie" but only polyester hoodie exists → full credit for recommending the hoodie OR stating no exact match
+
+    **6. Reasonable Effort Requirements**:
+    - Award **FULL credit** only if the agent demonstrates reasonable effort before resorting to alternatives (attempting the specified approach, encountering genuine blocker, THEN reporting/finding alternative)
+    - Award **PARTIAL credit** if agent immediately defaults to alternatives without attempting the specified approach when it was accessible
+    - Award **NO credit** for premature abandonment without reasonable attempt
+
+    **Instructions**:
+    1. Read the task description carefully.
+    2. Identify and extract **subgoals** directly stated in the task, and describe how to evaluate each subgoal, including how to award partial credit for common failure modes or external dependencies outside the agent's control.
+    3. Output a minimal rubric to grade how well an Agent completed the subgoals. You will format your output as a rubric with the following elements/fields
+
+    The rubric must be:
+    1. Formatted as json dictionary of a (possibly nested) list of "items"
+    2. Each Item in the rubric must contain the following fields IN ORDER:
+       - For CONDITIONAL criteria: ["criterion", "condition", "task_span", "description", "max_points", "justification", "earned_points"]
+       - For NON-CONDITIONAL criteria: ["criterion", "task_span", "description", "max_points", "justification", "earned_points"]
+       - The "condition" field should ONLY be present for conditional criteria (criteria that only apply when specific conditions are met)
+       - The "task_span" field is REQUIRED on every criterion (verbatim substring of the task, or "<critical-point>" for Critical Point boundary criteria only)
+    3. Choose the "max_points" judiciously to account for possible failure modes that could earn partial credit: goals that would have more failure modes deserve higher max_points.
+    4. The "description" should explain *what* goal the criteria is evaluating and *how* partial credit could be awarded to fairly penalize the agent's mistakes while accounting for external dependencies outside the agent's control.
+    5. For conditional criteria, the "condition" field must clearly state when the criterion applies (e.g., "Only applies if organic blueberries are unavailable")
+    6. Leave the "earned_points" and "justification" fields **empty** (since this rubric isn't being evaluated right now).
+    7. Do not make criteria for formatting/style unless stated explicitly in the Task.
+    8. Keep the rubric simple, following ONLY the main keypoints the task required. Do not overcomplicate the criteria or include optional items that were not explicitly mentioned.
+
+    **ANTI-PATTERN — Over-Specification / Hallucinated Sub-Goals**:
+    A common failure mode is inventing criteria that the task never asked for. If a criterion's task_span isn't a substring of the original task description (and it isn't the Critical Point boundary), the criterion is over-specifying.
+
+    Anti-example task: "Find the citation page for the City of Vancouver."
+    - WRONG criterion: "Display the citation number, fine amount, and payment due date" — the task did not ask for any of these specific fields. There is no "citation number" or "fine amount" in the task text.
+      * task_span: <none possible> → drop.
+    - WRONG criterion: "Provide instructions for paying the citation online" — the task did not ask for payment instructions.
+      * task_span: <none possible> → drop.
+    - RIGHT criterion: "Locate the citation page on the City of Vancouver site" [3 points]
+      * task_span: "citation page for the City of Vancouver"
+      * Description: Full credit if agent navigates to the citation/ticket page on the official cityofvancouver site, or if no such page exists and agent reports this. Partial credit for finding an unrelated city services page.
+
+    Anti-example task: "Search arXiv for the most recent paper on retrieval-augmented generation."
+    - WRONG criterion: "Output the abstract and author list of the paper" — task didn't ask for abstract or author list. The agent just needs to identify and report the paper.
+      * task_span: <none possible> → drop.
+    - RIGHT criterion: "Identify the most recent arXiv paper on retrieval-augmented generation" [4 points]
+      * task_span: "most recent paper on retrieval-augmented generation"
+
+    **The test**: For each criterion you draft, ask: "Can I copy a contiguous substring of the task that this criterion is evaluating?" If no, the criterion is over-specifying and must be dropped.
+
+    ==================
+    Example 1 (high level): "Book a reservation at a Mexican restaurant in the Northside of Chicago on 09/29/2025 for 2:45 PM at gayot.com."
+    High level rubric:
+        - Start on gayot.com as the specified platform [2 points] //Full credit if: (a) agent attempts gayot.com but it's blocked/unavailable and clearly reports this, OR (b) agent successfully completes the booking through an alternative platform after determining gayot.com cannot complete the booking
+        - Identify a Mexican restaurant in Chicago's Northside [3 points] //Full credit for correct identification. Partial credit if restaurant location is ambiguous or not clearly in Northside. No credit if wrong cuisine type when Mexican options exist
+        - Reach a reservation booking interface for the restaurant [2 points] //Full credit for ANY reservation booking interface (decoupled from platform criterion to avoid double-penalizing). Full credit if restaurant doesn't offer online booking and agent reports this
+        - Attempt date/time selection for 09/29/2025 at 2:45 PM [3 points] //Full credit if: (a) correct date/time selected, OR (b) that date/time is unavailable and agent clearly indicates this, OR (c) agent selects closest available alternative and explains why. No credit if wrong date selected when correct date is available
+        - Respect Critical Point boundaries (no personal info or final booking) [2 points] //Full credit for stopping before entering personal information. Deduct if agent unnecessarily crosses critical point
+
+    Takeaway: Make criteria as disjoint and non-overlapping as possible, e.g. do NOT make "Reach the reservation interface starting from gayot.com" a criterion bc this overlaps with the first criterion. Each criterion should clearly specify full credit scenarios for both success AND uncontrollable failure modes.

+${AXIS1_AMBIGUITY_DEFINITION}
+
+${CAT7_BULLETS}
+
+**EXAMPLES OF NON-AMBIGUOUS TASKS**
+1. Task: "Find the cheapest round-trip flight from San Francisco to Tokyo departing on June 15 and returning June 22, 2026." URL: "https://www.google.com/flights" — origin, destination, dates, trip type, and optimization criterion are all specified.
+2. Task: "Add a 16oz bag of Starbucks Pike Place ground coffee to the cart." URL: "https://www.amazon.com/" — the product, size, and action are specific enough.
+
+**EXAMPLES OF AMBIGUOUS TASKS**
+1. Task: "Browse apartments with at least 2 bedrooms…" URL: "https://craigslist.org/" — Craigslist requires a city; this is underspecified (7.1).
+2. Task: "Book a flight from NYC to London." URL: "https://www.google.com/flights" — travel dates not specified (7.1).
+3. Task: "Highlight over 'the' in file.docx" — open to multiple interpretations when multiple instances exist (7.2).
+
+---
+
+## Axis 2 — Invalid Task (Category 8)
+
+${AXIS2_INVALID_DEFINITION}
+
+${CAT8_BULLETS}
+
+**EXAMPLES OF VALID TASKS**
+1. "Find the cheapest round-trip flight from San Francisco to Tokyo." on Google Flights — site supports flight search.
+2. "Submit a job application for a software engineering role." on careers.google.com — site supports it.
+
+**EXAMPLES OF INVALID TASKS**
+1. "Log into my personal bank account…" — agent has no credentials (8.1 impossible).
+2. "Book a hotel room on LinkedIn." — LinkedIn is professional networking, not a travel site (8.1).
+3. "Download and launch GTA 6." — non-existent entity at time of release (8.1).
+4. Drug/piracy/prostitution-related tasks → 8.2 (illegal).
+5. NSFW-redirecting tasks → 8.3.
+6. Fraud, harassment, surveillance, discriminatory targeting → 8.2 / 8.4 (illegal + RAI).

+## Context
+
+Task: $task_definition
+
+URL: $url
+
+Applications: $apps
+
+Current Date: $date
+
+## Instructions
+
+Analyze the task across both axes. For each axis, provide reasoning and a classification. Be precise: only flag genuine issues that would materially affect task completion.
+
+**Guiding principles:**
+- A task that is merely difficult, tedious, or multi-step is NOT impossible.
+- A task that has minor formatting ambiguity is NOT ambiguous.
+- The current date is provided to help assess time-sensitive impossibility (e.g., expired events, future releases).
+
+**IMPORTANT**
+Output your answer in pure JSON format according to the following schema. The JSON object must be parsable as-is. DO NOT OUTPUT ANYTHING OTHER THAN JSON, AND DO NOT DEVIATE FROM THIS SCHEMA:
+
+{{
+    "reasoning_is_ambiguous": str,
+    "is_ambiguous": bool,
+    "ambiguity_codes": [str],
+    "reasoning_is_invalid": str,
+    "is_invalid": bool,
+    "invalid_task_codes": [str]
+}}

+title: Act
+description: 'Interact with a web page'
+---
+
+## What is `act()`?
+``` typescript
+page.act("click on add to cart")
+```
+`act` enables Stagehand to perform **individual** actions on a web page. Use it to build self-healing and deterministic automations that adapt to website changes. 
+
+## Why use `act()`?
+
+<CardGroup cols={2}>
+  <Card title="Natural Language Instructions" icon="wand-magic-sparkles" href="#using-act">
+    Write automation in plain English. No selectors or complex syntax.
+  </Card>
+  <Card title="Precise Control" icon="crosshairs" href="#best-practices">
+    Build automations step by step. Define exactly what happens at every moment.
+  </Card>
+  <Card title="Self-Healing" icon="bandage" href="#ensure-reliable-actions">
+    Actions automatically adapt when websites change.
+  </Card>
+  <Card title="Caching" icon="repeat" href="#reduce-model-costs">
+    Cache actions to avoid LLM calls and ensure consistent execution across runs.
+  </Card>
+</CardGroup>
+
+## Using `act()`
+
+Use `act` to perform single actions in your automation. Here's how to click a button:
+
+<CodeGroup>
+```typescript TypeScript
+await page.goto("https://example-store.com");
+await page.act("click the add to cart button");
+```
+
+```python Python
+await page.goto("https://example-store.com")
+await page.act("click the add to cart button")
+```
+</CodeGroup>
+
+With `act`, breaking complex actions into small, single-step actions works best. If you need to orchestrate multi-step flows, use multiple `act` commands or `agent`.
+
+<Accordion title="Suggested actions">
+
+| Action | Example instruction |
+|--------|---------------------|
+| Click | `click the button` |
+| Fill | `fill the field with <value>` |
+| Type | `type <text> into the search box` |
+| Press | `press <key> in the search field` |
+| Scroll | `scroll to <position>` |
+| Select from dropdown | `select <value> from the dropdown` |
+</Accordion>
+
+<Tabs>
+<Tab title="Do this">
+Break your task into single-step actions.
+
+<CodeGroup>
+```typescript TypeScript
+// Break it into single-step actions
+await page.act("open the filters panel");
+await page.act("choose 4-star rating");
+await page.act("click the apply button");
+```
+
+```python Python
+# Break it into single-step actions
+await page.act("open the filters panel")
+await page.act("choose 4-star rating")
+await page.act("click the apply button")
+```
+</CodeGroup>
+</Tab>
+
+<Tab title="Don't do this">
+For multi-step tasks, use [`agent()`](/v2/basics/agent) instead.
+
+<CodeGroup>
+```typescript TypeScript
+// Too complex - trying to do multiple things at once
+await page.act("open the filters panel, choose 4-star rating, and click apply");
+```
+
+```python Python
+# Too complex - trying to do multiple things at once
+await page.act("open the filters panel, choose 4-star rating, and click apply")
+```
+</CodeGroup>
+</Tab>
+</Tabs>
+
+### Advanced Configuration
+
+For advanced scenarios, you can configure additional options:
+
+<CodeGroup>
+```typescript TypeScript
+// Dynamic food search with advanced options
+const foodItem = "organic quinoa";
+
+await page.act({
+  action: "Type %foodItem% in the search box and press enter",
+  variables: {
+    foodItem: foodItem
+  },
+  modelName: "google/gemini-2.5-pro",
+  modelClientOptions: {
+    modelApiKey: process.env.GOOGLE_API_KEY,
+  },
+  iframes: true, // Search within iframes if needed
+  domSettleTimeoutMs: 45000, // Wait longer for dynamic content
+  timeoutMs: 60000 // Extended timeout for slow-loading forms
+});
+```
+
+```python Python
+# Dynamic food search with advanced options
+food_item = "organic quinoa"
+
+await page.act({
+  "action": "Type %foodItem% in the search box and press enter",
+  "variables": {
+    "foodItem": food_item
+  },
+  "modelName": "google/gemini-2.5-pro",
+  "modelClientOptions": {
+    "modelApiKey": os.environ.get("GOOGLE_API_KEY")
+  },
+  "iframes": True, # Search within iframes if needed
+  "domSettleTimeoutMs": 45000, # Wait longer for dynamic content
+  "timeoutMs": 60000 # Extended timeout for slow-loading forms
+})
+```
+</CodeGroup>
+  
+<Note>
+Shadow DOM support is now available! Set `experimental: true` in your Stagehand configuration to enable it. See the [configuration guide](/v2/configuration/browser) for more details.
+</Note>
+
+
+
+
+
+## Best practices
+
+### Ensure reliable actions
+
+Use `observe()` to discover candidate actions on the current page and plan reliably. It returns a list of suggested actions (with selector, description, method, and arguments). You can pass an observed action directly to `act` to execute it.
+
+<CodeGroup>
+```typescript TypeScript
+const [action] = await page.observe("click the login button");
+
+if (action) {
+  await page.act(action);
+}
+```
+
+```python Python
+results = await page.observe("click the login button")
+
+if results:
+    await page.act(results[0])
+```
+</CodeGroup>
+
+<Card title="Analyze pages with observe()" icon="magnifying-glass" iconType="sharp-solid" href="/v2/basics/observe">
+  Plan actions with `observe()` before executing with `act`.
+</Card>
+
+### Reduce model costs
+
+Cache observed actions to avoid repeated LLM calls and ensure consistent execution.
+
+<CodeGroup>
+```typescript TypeScript
+// Cost-optimized actions with caching
+const actionCache = new Map();
+
+const getCachedAction = async (instruction: string) => {
+  if (actionCache.has(instruction)) {
+    return actionCache.get(instruction);
+  }
+  
+  const [action] = await page.observe(instruction);
+  actionCache.set(instruction, action);
+  return action;
+};
+
+// Reuse cached actions
+const loginAction = await getCachedAction("click the login button");
+await page.act(loginAction);
+```
+
+```python Python
+# Cost-optimized actions with caching
+action_cache = {}
+
+async def get_cached_action(instruction: str):
+    if instruction in action_cache:
+        return action_cache[instruction]
+    
+    results = await page.observe(instruction)
+    if results:
+        action = results[0]
+        action_cache[instruction] = action
+        return action
+    
+    return None
+
+# Reuse cached actions
+login_action = await get_cached_action("click the login button")
+if login_action:
+    await page.act(login_action)

+</Card>
+
+### Secure your automations
+
+Variables will not be shared with LLM providers. Use them for passwords, API keys, and other sensitive data.
+
+
+<Note>
+Load sensitive data from environment variables using `.env` files. Never hardcode API keys, passwords, or other secrets directly in your code.
+</Note>
+
+<CodeGroup>
+```typescript TypeScript
+await page.act({
+  action: "enter %username% in the email field",
+  variables: {
+    username: "user@example.com"
+  }
+});
+
+await page.act({
+  action: "enter %password% in the password field",
+  variables: {
+    password: process.env.USER_PASSWORD
+  }
+});
+```
+
+```python Python
+# If using Python, set `use_api: true` in your Stagehand configuration
+
+await page.act(
+  "enter %username% in the email field",
+  variables={
+      "username": "user@example.com"
+  }
+)
+
+await page.act(
+  "enter %password% in the password field",
+  variables={
+      "password": os.environ.get("USER_PASSWORD")
+  }
+)
+```
+</CodeGroup>
+
+<Warning>
+When handling sensitive data, set `verbose: 0` in your Stagehand configuration to prevent secrets from appearing in logs. See the [configuration guide](/v2/configuration/browser) for more details.

+
+## Troubleshooting
+
+<AccordionGroup>
+
+
+<Accordion title="Method not supported">
+**Problem**: `act` fails with "method not supported" error
+
+**Solutions**:
+- Use clear and detailed instructions for what you want to accomplish
+- Review our [evals](https://stagehand.dev/evals) to find the best models for your use case
+- Use [`observe()`](/v2/basics/observe) and verify the resulting action is within a list of expected actions
+
+**Solution 1: Validate with observe**
+
+<CodeGroup>
+```typescript TypeScript
+const prompt = "click the submit button";
+const expectedMethod = "click";
+
+try {
+  await page.act(prompt);
+} catch (error) {
+  if (error.message.includes("method not supported")) {
+    // Observe the same prompt to get the planned action
+    const [action] = await page.observe(prompt);
+    
+    if (action && action.method === expectedMethod) {
+      await page.act(action);
+    } else {
+      throw new Error(`Unsupported method: expected "${expectedMethod}", got "${action?.method}"`);
+    }
+  } else {
+    throw error;
+  }
+}
+```
+
+```python Python
+prompt = "click the submit button"
+expected_method = "click"
+
+try:
+    await page.act(prompt)
+except Exception as error:
+    if "method not supported" in str(error):
+        # Observe the same prompt to get the planned action
+        results = await page.observe(prompt)
+        
+        if results and results[0].method == expected_method:
+            await page.act(results[0])
+        else:
+            method = results[0].method if results else "unknown"
+            raise Exception(f'Unsupported method: expected "{expected_method}", got "{method}"')
+    else:
+        raise error
+```
+</CodeGroup>
+
+**Solution 2: Retry with exponential backoff**
+
+<CodeGroup>
+```typescript TypeScript
+// Retry with exponential backoff for intermittent issues
+const prompt = "click the submit button";
+const maxRetries = 3;
+
+for (let attempt = 0; attempt <= maxRetries; attempt++) {
+  try {

+  } catch (error) {
+    if (error.message.includes("method not supported") && attempt < maxRetries) {
+      // Exponential backoff: wait 2^attempt seconds
+      const delay = Math.pow(2, attempt) * 1000;
+      console.log(`Retry ${attempt + 1}/${maxRetries} after ${delay}ms`);
+      await new Promise(resolve => setTimeout(resolve, delay));
+    } else {
+      throw error;
+    }
+  }
+}
+```
+
+```python Python
+# Retry with exponential backoff for intermittent issues
+import asyncio
+
+prompt = "click the submit button"
+max_retries = 3
+
+for attempt in range(max_retries + 1):
+    try:
+        timeout = 10000 + (attempt * 5000)
+        await page.act(prompt, {"timeoutMs": timeout})
+        break  # Success, exit retry loop
+    except Exception as error:
+        if "method not supported" in str(error) and attempt < max_retries:

+```
+</CodeGroup>
+
+</Accordion>
+
+<Accordion title="Action failed or timed out">
+**Problem**: `act` times out or fails to complete action (often due to element not found)
+
+**Solutions**:
+- Ensure page has fully loaded
+- Check if content is in iframes: [Learn more about working with iframes](/v2/best-practices/working-with-iframes)
+- Increase action timeout
+- Use `observe()` first to verify element exists

+</CodeGroup>
+</Accordion>
+
+<Accordion title="Incorrect element selected">
+**Problem**: `act` performs action on wrong element
+
+**Solutions**:
+- Be more specific in instructions: include visual cues, position, or context
+- Use `observe()` to preview which element will be selected
+- Add contextual information: "the search button in the header"
+- Use unique identifiers when available
+
+<CodeGroup>

+
+## Using `agent()`
+
+There are two ways to create agents in Stagehand:
+
+### Computer Use Agents
+
+Use computer use agents with specialized models from OpenAI or Anthropic: 
+
+<CodeGroup>
+```typescript TypeScript
+const agent = stagehand.agent({
+  provider: "anthropic",
+  model: "claude-sonnet-4-20250514",
+  instructions: "You are a helpful assistant that can use a web browser.",
+  options: {
+    apiKey: process.env.ANTHROPIC_API_KEY,
+  },
+});
+await agent.execute("apply for a job at Browserbase")
+```
+
+```python Python
+agent = stagehand.agent(
+    model="claude-sonnet-4-20250514",
+    instructions="You are a helpful assistant that can use a web browser.",
+    options={
+        "api_key": os.getenv("ANTHROPIC_API_KEY"),
+    },
+)
+await agent.execute("apply for a job at Browserbase")
+```
+</CodeGroup>
+
+<Callout icon="code" color="#6ec202" iconType="regular">View or run the example template [here](https://www.browserbase.com/templates/gemini-cua)</Callout>
+
+### Use Stagehand Agent with Any LLM
+
+Use the agent without specifying a provider to utilize any model or LLM provider:
+
+<Note>Non CUA agents are currently only supported in TypeScript</Note>
+
+```typescript TypeScript
+const agent = stagehand.agent();
+await agent.execute("apply for a job at Browserbase")
+```
+
+
+## MCP Integrations
+
+Agents can be enhanced with external tools and services through MCP (Model Context Protocol) integrations. This allows your agent to access external APIs and data sources beyond just browser interactions.
+
+<CodeGroup>
+```typescript TypeScript (Pass URL)
+const agent = stagehand.agent({
+  provider: "openai",
+  model: "computer-use-preview",
+  integrations: [
+    `https://mcp.exa.ai/mcp?exaApiKey=${process.env.EXA_API_KEY}`,
+  ],
+  instructions: `You have access to web search through Exa. Use it to find current information before browsing.`,
+  options: {
+    apiKey: process.env.OPENAI_API_KEY,
+  },
+});
+
+await agent.execute("Search for the best headphones of 2025 and go through checkout for the top recommendation");
+```
+
+```typescript TypeScript (Create Connection)
+import { connectToMCPServer } from "@browserbasehq/stagehand";
+
+const supabaseClient = await connectToMCPServer(
+  `https://server.smithery.ai/@supabase-community/supabase-mcp/mcp?api_key=${process.env.SMITHERY_API_KEY}`
+);
+
+const agent = stagehand.agent({
+  provider: "openai",
+  model: "computer-use-preview",
+  integrations: [supabaseClient],
+  instructions: `You can interact with Supabase databases. Use these tools to store and retrieve data.`,
+  options: {
+    apiKey: process.env.OPENAI_API_KEY,
+  },
+});
+
+await agent.execute("Search for restaurants and save the first result to the database");
+```

+MCP integrations enable agents to be more powerful by combining browser automation with external APIs, databases, and services. The agent can intelligently decide when to use browser actions versus external tools.
+</Tip>
+
+<Warning>
+Stagehand uses a 1288x711 viewport by default (the optimal size for Computer Use Agents). Other viewport sizes may reduce performance. If you need to modify the viewport, you can edit in the [Browser Configuration](/v2/configuration/browser).
+</Warning>
+
+
+## Available Models
+
+Use specialized computer use models (e.g., `computer-use-preview` from OpenAI or `claude-sonnet-4-20250514` from Anthropic)
+
+<Card title="Available Models" icon="robot" href="/v2/configuration/models">
+  Check out the guide on how to use different models with Stagehand.
+</Card>
+
+## Agent Execution Configuration
+
+Control the maximum number of steps the agent can take to complete the task using the `maxSteps` parameter.
+
+<CodeGroup>
+```typescript TypeScript
+// Set maxSteps to control how many actions the agent can take
+await agent.execute({
+  instruction: "Sign me up for a library card",
+  maxSteps: 15 // Agent will stop after 15 steps if task isn't complete
+});
+```
+
+```python Python
+# Set max_steps to control how many actions the agent can take
+result = await agent.execute({
+    "instruction": "Sign me up for a library card",
+    "max_steps": 15  # Agent will stop after 15 steps if task isn't complete
+})
+```
+</CodeGroup>
+
+For complex tasks, increase the `maxSteps` limit and check task success.
+
+<CodeGroup>
+```typescript TypeScript
+// Complex multi-step task requiring more actions
+const result = await agent.execute({
+  instruction: "Find and apply for software engineering jobs, filtering by remote work and saving 3 applications",
+  maxSteps: 30, // Higher limit for complex workflows
+});
+
+// Check if the task completed successfully
+if (result.success === true) {
+  console.log("Task completed successfully!");
+} else {
+  console.log("Task failed or was incomplete");
+}
+```
+
+```python Python
+# Complex multi-step task requiring more actions
+result = await agent.execute({
+    "instruction": "Find and apply for software engineering jobs, filtering by remote work and saving 3 applications",
+    "max_steps": 30  # Higher limit for complex workflows
+})
+
+# Check if the task completed successfully
+if result.success == True:
+    print("Task completed successfully!")
+else:
+    print("Task failed or was incomplete")
+```
+</CodeGroup>
+
+## Best Practices
+
+Following these best practices will improve your agent's success rate, reduce execution time, and minimize unexpected errors during task completion.
+
+### Start on the Right Page
+Navigate to your target page before executing tasks:
+
+<Tabs>
+<Tab title="Do this">
+<CodeGroup>
+```typescript TypeScript
+await page.goto('https://github.com/browserbase/stagehand');
+await agent.execute('Get me the latest PR on the stagehand repo');
+```
+
+```python Python
+await page.goto("https://github.com/browserbase/stagehand")
+result = await agent.execute("Get me the latest PR on the stagehand repo")
+```
+</CodeGroup>
+</Tab>
+
+<Tab title="Don't do this">
+<CodeGroup>
+```typescript TypeScript
+await agent.execute('Go to GitHub and find the latest PR on browserbase/stagehand');
+```
+
+```python Python
+result = await agent.execute("Go to GitHub and find the latest PR on browserbase/stagehand")
+```
+</CodeGroup>
+</Tab>
+</Tabs>
+
+
+### Be Specific
+Provide detailed instructions for better results:
+
+<Tabs>
+<Tab title="Do this">
+<CodeGroup>
+```typescript TypeScript
+await agent.execute("Find Italian restaurants in Brooklyn that are open after 10pm and have outdoor seating");
+```
+
+```python Python
+result = await agent.execute("Find Italian restaurants in Brooklyn that are open after 10pm and have outdoor seating")
+```
+</CodeGroup>
+</Tab>
+
+<Tab title="Don't do this">
+<CodeGroup>
+```typescript TypeScript
+await agent.execute("Find a restaurant");
+```
+
+```python Python
+result = await agent.execute("Find a restaurant")
+```
+</CodeGroup>
+</Tab>
+</Tabs>
+
+## Troubleshooting
+
+<AccordionGroup>
+
+
+<Accordion title="Agent is stopping before completing the task">
+**Problem**: Agent stops before finishing the requested task
+
+**Solutions**:
+- Check if the agent is hitting the maxSteps limit (default is 20)
+- Increase maxSteps for complex tasks: `maxSteps: 30` or higher
+- Break very complex tasks into smaller sequential executions
+
+```typescript
+// Increase maxSteps for complex tasks
+await agent.execute({
+  instruction: "Complete the multi-page registration form with all required information",
+  maxSteps: 40 // Increased limit for complex task
+});
+
+// Or break into smaller tasks with success checking
+const firstResult = await agent.execute({
+  instruction: "Fill out page 1 of the registration form", 
+  maxSteps: 15
+});
+
+// Only proceed if the first task was successful
+if (firstResult.success === true) {
+  await agent.execute({
+    instruction: "Navigate to page 2 and complete remaining fields",
+    maxSteps: 15
+  });
+} else {
+  console.log("First task failed, stopping execution");
+}
+```
+</Accordion>
+
+<Accordion title="Agent is failing to click the proper elements">
+**Problem**: Agent clicks on wrong elements or fails to interact with the correct UI components
+
+**Solutions**:
+- Ensure proper viewport size: Stagehand uses `1288x711` by default (optimal for Computer Use models)
+- Avoid changing viewport dimensions as other sizes may reduce performance

+description: Extract structured data from a webpage
+---
+
+## What is `extract()`?
+
+```typescript
+page.extract("extract the name of the repository");
+```
+
+`extract` grabs structured data from a webpage. You can define your schema with [zod](https://github.com/colinhacks/zod) (TypeScript) or [pydantic](https://github.com/pydantic/pydantic) (Python). If you do not want to define a schema, you can also call `extract` with just a [natural language prompt](#prompt-only-extraction), or call `extract` [with no parameters](#extract-with-no-parameters).
+
+## Why use `extract()`?
+
+<CardGroup cols={2}>
+  <Card title="Structured" icon="brackets-curly" href="#list-of-objects-extraction">

+  </Card>
+</CardGroup>
+
+<Note>
+For TypeScript, the extract schemas are defined using zod schemas.
+
+For Python, the extract schemas are defined using pydantic models.
+</Note>
+
+## Using `extract()`
+
+### Single object Extraction
+
+Here is how an `extract` call might look for a single object:
+
+<CodeGroup>
+```typescript TypeScript
+import { z } from 'zod/v3';
+
+const item = await page.extract({
+  instruction: "extract the price of the item",
+  schema: z.object({
+    price: z.number(),
+  }),
+});
+```
+
+```python Python
+from pydantic import BaseModel
+
+class Extraction(BaseModel):
+    price: float
+
+item = await page.extract(
+    "extract the price of the item", 
+    schema=Extraction
+)
+```
+</CodeGroup>
+
+Your output schema will look like:
+```Example
+{ price: number }
+```
+
+### List of objects Extraction
+
+Here is how an `extract` call might look for a list of objects.
+
+<CodeGroup>
+```typescript TypeScript
+import { z } from 'zod/v3';
+
+const apartments = await page.extract({
+  instruction:
+    "Extract ALL the apartment listings and their details, including address, price, and square feet.",
+  schema: z.object({
+    list_of_apartments: z.array(
+      z.object({
+        address: z.string(),
+        price: z.string(),
+        square_feet: z.string(),
+      }),
+    ),
+  })
+})
+
+console.log("the apartment list is: ", apartments);
+```
+
+```python Python
+from pydantic import BaseModel
+
+class Apartment(BaseModel):
+    address: str
+    price: str
+    square_feet: str
+
+class Apartments(BaseModel):
+    list_of_apartments: list[Apartment]
+
+apartments = await page.extract(
+    "Extract ALL the apartment listings and their details as a list, including address, price, and square feet for each apartment",
+    schema=Apartments
+)
+
+print("the apartment list is: ", apartments)
+```
+</CodeGroup>
+
+Your output schema will look like:
+```Example
+list_of_apartments: [
+    {
+      address: "street address here",
+      price: "$1234.00",
+      square_feet: "700"
+    },
+    {
+        address: "another address here",
+        price: "1010.00",
+        square_feet: "500"
+    },
+    ...
+]
+```
+
+### Prompt-only Extraction
+
+You can call `extract` with just a natural language prompt:
+
+<CodeGroup>
+```typescript TypeScript
+const result = await page.extract("extract the name of the repository");
+```
+
+```python Python
+result = await page.extract("extract the name of the repository")
+```
+</CodeGroup>
+
+When you call `extract` with just a prompt, your output schema will look like:
+```Example
+{ extraction: string }
+```
+
+### Extract with no parameters
+
+Here is how you can call `extract` with no parameters.
+
+<CodeGroup>
+```typescript TypeScript
+const pageText = await page.extract();
+```
+
+```python Python
+pageText = await page.extract()
+```
+</CodeGroup>
+
+Output schema:
+```Example
+{ pageText: string }
+```
+
+Calling `extract` with no parameters will return hierarchical tree representation of the root DOM. This will not be passed through an LLM. It will look something like this:
+
+```
+Accessibility Tree:
+[0-2] RootWebArea: What is Stagehand? - 🤘 Stagehand
+  [0-37] scrollable
+    [0-118] body
+      [0-241] scrollable
+        [0-242] div
+          [0-244] link: 🤘 Stagehand home page light logo
+            [0-245] span
+              [0-246] StaticText: 🤘 Stagehand
+              [0-247] StaticText: home page
+```
+
+## Best practices
+
+
+### Extract with Context
+
+You can provide additional context to your schema to help the model extract the data more accurately.
+
+<CodeGroup>
+```typescript TypeScript
+import { z } from 'zod/v3';
+
+const apartments = await page.extract({
+ instruction:
+   "Extract ALL the apartment listings and their details, including address, price, and square feet.",
+ schema: z.object({
+   list_of_apartments: z.array(
+     z.object({
+       address: z.string().describe("the address of the apartment"),
+       price: z.string().describe("the price of the apartment"),
+       square_feet: z.string().describe("the square footage of the apartment"),
+     }),
+   ),
+ })
+})
+```
+
+```python Python
+from pydantic import BaseModel, Field
+
+class Apartment(BaseModel):
+    address: str = Field(..., description="the address of the apartment")
+    price: str = Field(..., description="the price of the apartment")
+    square_feet: str = Field(..., description="the square footage of the apartment")
+
+class Apartments(BaseModel):
+    list_of_apartments: list[Apartment]
+
+apartments = await page.extract(
+    "Extract ALL the apartment listings and their details as a list. For each apartment, include: the address of the apartment, the price of the apartment, and the square footage of the apartment",
+    schema=Apartments
+)
+```
+</CodeGroup>
+
+### Link Extraction
+<Note>
+To extract links or URLs, in the TypeScript version of Stagehand, you'll need to define the relevant field as `z.string().url()`.
+In Python, you'll need to define it as `HttpUrl`.
+</Note>
+
+Here is how an `extract` call might look for extracting a link or URL. This also works for image links.
+
+<CodeGroup>
+```typescript TypeScript
+import { z } from 'zod/v3';
+
+const extraction = await page.extract({
+  instruction: "extract the link to the 'contact us' page",
+  schema: z.object({
+    link: z.string().url(), // note the usage of z.string().url() here
+  }),
+});
+
+console.log("the link to the contact us page is: ", extraction.link);
+```
+
+```python Python
+from pydantic import BaseModel, HttpUrl
+
+class Extraction(BaseModel):
+    link: HttpUrl # note the usage of HttpUrl here
+
+extraction = await page.extract(
+    "extract the link to the 'contact us' page", 
+    schema=Extraction
+)
+
+print("the link to the contact us page is: ", extraction.link)
+```
+</CodeGroup>
+
+<Tip>
+Inside Stagehand, extracting links works by asking the LLM to select an ID. Stagehand looks up that ID in a mapping of IDs -> URLs. When logging the LLM trace, you should expect to see IDs. The actual URLs will be included in the final `ExtractResult`.
+</Tip>
+
+## Troubleshooting
+
+<AccordionGroup>
+<Accordion title="Empty or partial results">
+**Problem**: `extract()` returns empty or incomplete data
+
+**Solutions**:
+- **Check your instruction clarity**: Make sure your instruction is specific and describes exactly what data you want to extract
+- **Verify the data exists**: Use `page.observe()` first to confirm the data is present on the page
+- **Wait for dynamic content**: If the page loads content dynamically, use `page.act("wait for the content to load")` before extracting
+
+**Solution: Wait for content before extracting**
+<CodeGroup>
+```typescript TypeScript
+// Wait for content before extracting
+await page.act("wait for the product listings to load");
+const products = await page.extract({
+  instruction: "extract all product names and prices",
+  schema: z.object({
+    products: z.array(z.object({
+      name: z.string(),
+      price: z.string()
+    }))
+  })
+});
+```
+
+```python Python
+# Wait for content before extracting
+await page.act("wait for the product listings to load")
+products = await page.extract(
+    "extract all product names and prices",
+    schema=ProductList
+)
+```
+</CodeGroup>
+</Accordion>
+
+<Accordion title="Schema validation errors">
+**Problem**: Getting schema validation errors or type mismatches
+
+**Solutions**:
+- **Use optional fields**: Make fields optional with `z.optional()` (TypeScript) or `Optional[type]` (Python) if the data might not always be present
+- **Use flexible types**: Consider using `z.string()` instead of `z.number()` for prices that might include currency symbols
+- **Add descriptions**: Use `.describe()` (TypeScript) or `Field(description="...")` (Python) to help the model understand field requirements
+
+**Solution: More flexible schema**
+<CodeGroup>
+```typescript TypeScript
+const schema = z.object({
+  price: z.string().describe("price including currency symbol, e.g., '$19.99'"),
+  availability: z.string().optional().describe("stock status if available"),
+  rating: z.number().optional()
+});
+```
+
+```python Python
+class FlexibleProduct(BaseModel):
+    price: str = Field(description="price including currency symbol, e.g., '$19.99'")
+    availability: Optional[str] = Field(default=None, description="stock status if available")
+    rating: Optional[float] = None
+```
+</CodeGroup>
+</Accordion>
+
+<Accordion title="Inconsistent results">
+**Problem**: Extraction results vary between runs
+
+**Solutions**:
+- **Be more specific in instructions**: Instead of "extract prices", use "extract the numerical price value for each item"
+- **Use context in schema descriptions**: Add field descriptions to guide the model
+- **Combine with observe**: Use `page.observe()` to understand the page structure first
+
+**Solution: Validate with observe first**
+<CodeGroup>
+```typescript TypeScript
+// First observe to understand the page structure
+const elements = await page.observe("find all product listings");
+console.log("Found elements:", elements.map(e => e.description));
+
+// Then extract with specific targeting
+const products = await page.extract({
+  instruction: "extract name and price from each product listing shown on the page",
+  schema: z.object({
+    products: z.array(z.object({
+      name: z.string().describe("the product title or name"),
+      price: z.string().describe("the price as displayed, including currency")
+    }))
+  })
+});
+```
+
+```python Python
+# First observe to understand the page structure
+elements = await page.observe("find all product listings")
+print("Found elements:", [e.description for e in elements])
+
+# Then extract with specific targeting
+products = await page.extract(
+    "extract name and price from each product listing shown on the page",
+    schema=ProductSchema
+)
+```
+</CodeGroup>
+</Accordion>
+
+<Accordion title="Performance issues">
+**Problem**: Extraction is slow or timing out
+
+**Solutions**:
+- **Reduce scope**: Extract smaller chunks of data in multiple calls rather than everything at once
+- **Use targeted instructions**: Be specific about which part of the page to focus on
+- **Consider pagination**: For large datasets, extract one page at a time
+- **Increase timeout**: Use `timeoutMs` parameter for complex extractions
+
+**Solution: Break down large extractions**

+
+## What is `observe()`?
+``` typescript
+page.observe("Find the login button")
+```
+
+`observe` allows you to turn any page into a checklist of reliable, executable actions. It discovers key elements, ranks likely next steps, and returns structured actions (selector, method, args) you can run instantly with `act` or use to precisely target `extract` so workflows are faster, cheaper, and more resilient.
+
+## Why use `observe()`?
+
+<CardGroup cols={2}>
+  <Card title="Explore" icon="compass" href="/v2/basics/observe#observe-with-act">
+    When you're unsure what's on a page or need to discover available actions

+    Before performing critical actions to ensure elements exist
+  </Card>
+</CardGroup>
+
+## Using `observe()`
+
+Calling `observe` supercharges other Stagehand methods. Use it to plan workflows, speed up `act`, and precisely target `extract`. Using `observe` helps you explore what's possible on a page by giving you a list of suggested actions.
+
+<CodeGroup>
+```typescript TypeScript
+// Plan & validate
+const buttons = await page.observe("Find the log in / sign up buttons");
+```
+```python Python
+# Plan & validate
+buttons = await page.observe("Find the log in / sign up buttons")
+```
+</CodeGroup>
+
+This will return a list of suggestions with the following structure
+```json
+{
+  "selector": "xpath=/html/body/header/div/button[1]",
+  "description": "Log in button in the top right corner",
+  "method": "click",
+  "arguments": []
+}
+```
+
+### Observe with Act
+
+You can **validate** the action (method, selector, arguments...) and then pass it to `act` to **avoid extra LLM inference**.
+
+<Note>
+**Performance Tip**: Acting on multiple `observe` suggestions will minimize the number of LLM calls for multi-step actions and speed up your workflow 2-3x.
+</Note>
+
+<CodeGroup>
+```typescript TypeScript
+await page.act(buttons[0]); // No LLM!
+```
+```python Python
+await page.act(buttons[0]) # No LLM!
+```
+</CodeGroup>
+
+#### Plan ahead
+
+You can use multiple suggestions from `observe` to preview a batch of actions. For example, when filling a form you could ask `observe` to find all the fields and then pass them in to `act`. **Call the LLM once, act multiple times**.
+
+<CodeGroup>
+```typescript TypeScript
+const fields = await page.observe("Find all the fields in the form");
+for (const field of fields) {
+  await page.act(field); // No LLM!
+}
+```
+```python Python
+fields = await page.observe("Find all the fields in the form")
+for field in fields:
+  await page.act(field) # No LLM!
+```
+</CodeGroup>
+
+### Observe and Extract
+
+Using `observe` to focus `extract` on a specific section of the page (like a table, a form, a list...) minimizes the context needed for an extraction. 
+<Tip>
+**Savings Tip**: Pass the selector to `extract` to reduce LLM token usage by 10x for verbose websites!
+</Tip>
+
+<CodeGroup>
+```typescript TypeScript
+// Use observe to validate elements before extraction
+const [ table ] = await page.observe("Find the data table");
+
+const { data } = await page.extract({
+  instruction: "Extract data from the table",
+  schema: z.object({
+    data: z.string()
+  }),
+  selector: table.selector // Reduce context scope needed for extraction
+});
+```
+```python Python
+# Use observe to validate elements before extraction
+[ table ] = await page.observe("Find the data table")
+
+extraction = await page.extract(
+  "Extract data from the table",
+  schema=Data, # Pydantic schema
+  selector=table.selector # Reduce context scope needed for extraction
+)
+```
+</CodeGroup>
+
+## Best Practices
+
+### Choose the right commands
+
+<Tabs>
+<Tab title="Do this">
+
+- Use `observe` when a yes/no answer will gate an action (e.g., "Find the Submit button"), then conditionally `act`.
+- Use `extract` for information-only questions (e.g., "What’s the page title?", "How many results are listed?").
+
+</Tab>
+
+<Tab title="Don't do this">
+
+- Don’t call `extract` to locate elements you plan to click next.
+- Don’t call `observe` to answer info-only questions that won’t lead to an action.
+
+</Tab>
+</Tabs>
+- **Discover and plan with `observe`**: Use `observe("Find…")` to map actionable elements and preview next steps.
+- **Scope `extract` with selectors from `observe`**: First `observe("Find the data table")`, then pass `selector` to `extract` to reduce tokens and boost accuracy.
+
+### Conserve LLM tokens
+
+Optimize performance by directly passing `ObserveResult` to `act` (e.g., `await page.act(results[0])`) to save LLM tokens. Batch operations by using `observe` once to find elements, then act on each. Cache and reuse stable `observe` results for familiar pages, using self-healing if layouts change.

+  Check out the guide on how to build your own action cache
+</Card>
+
+### Improve Accuracy
+
+Be precise with instructions, e.g., "Find the primary CTA in the hero" for better results. For iframes, set `iframes: true` and wait for `networkidle`. Use `observe` selectors in `extract` to limit context.

+</Card>
+
+### Action Validation
+
+Before performing critical actions, validate the suggestion's `method`, `selector`, and `arguments` to prevent misclicks. If a direct `act` fails, use `observe` with the same prompt to verify the method, then proceed with the suggested action.
+
+<CodeGroup>
+```typescript TypeScript
+const prompt = "click the submit button";
+const expectedMethod = "click";
+
+try {
+  await page.act(prompt);
+} catch (error) {
+  if (error.message.includes("method not supported")) {
+    // Observe the same prompt to get the planned action
+    const [action] = await page.observe(prompt);
+    
+    if (action && action.method === expectedMethod) {
+      await page.act(action);
+    } else {
+      throw new Error(`Unsupported method: expected "${expectedMethod}", got "${action?.method}"`);
+    }
+  } else {
+    throw error;
+  }
+}
+```
+
+```python Python
+prompt = "click the submit button"
+expected_method = "click"
+
+try:
+    await page.act(prompt)
+except Exception as error:
+    if "method not supported" in str(error):
+        # Observe the same prompt to get the planned action
+        results = await page.observe(prompt)
+        
+        if results and results[0].method == expected_method:
+            await page.act(results[0])
+        else:
+            method = results[0].method if results else "unknown"
+            raise Exception(f'Unsupported method: expected "{expected_method}", got "{method}"')
+    else:
+        raise error
+```
+</CodeGroup>
+
+## Troubleshooting
+
+<AccordionGroup>
+<Accordion title="No elements found">
+**Problem**: `observe` returns empty array
+
+**Solutions**:
+- Make sure the element exists on the page
+- Use explicit instructions to find the element
+- Ensure page has fully loaded
+- Look at the [debugging logs](/v2/configuration/logging), if the element is there then the LLM might be hallucinating/not catching it. 
+</Accordion>
+
+<Accordion title="Inaccurate element descriptions">
+**Problem**: Descriptions don't match actual elements
+
+**Solutions**:
+- Use more capable models: check [evals](https://stagehand.dev/evals) for the best models for your use case
+- Provide more specific instructions
+- Log inference to file (see [debugging logs](/v2/configuration/logging#llm-inference-logging)) to get an LLM trace
+
+</Accordion>
+<Accordion title="Wrong method identified">
+**Problem**: The method identified is not valid
+
+**Solutions**:
+- Check the [supported actions](/v2/basics/act)
+- Provide more specific instructions
+- Validate the method, if invalid override with one of the supported ones

+title: Agent Fallbacks
+description: "A failsafe when unexpected page changes add extra steps"
+---
+
+## When to use
+
+Use an agent fallback as a failsafe when a one step action unexpectedly becomes a multi-step flow.
+
+## How it works
+
+1. [`act()`](/v2/basics/act) is attempted for the direct action
+2. If it fails, [`agent()`](/v2/basics/agent) figures out the new path
+3. Agent completes all needed steps (open menu → click button)
+
+### Example scenario
+
+**Before**: Sign in button was in the header  
+**After**: Sign in now requires: Click account menu → Click "Sign in" option
+
+A single `act("click sign in")` can't handle this change. The agent fallback can discover and execute both steps.
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+try {
+  await page.act("click the 'Sign In' button");
+} catch (err) {
+  console.log("Agent fallback triggered");
+
+  const agent = stagehand.agent({
+    provider: "anthropic",
+    model: "claude-sonnet-4-20250514",
+    instructions: "You are a helpful assistant that can use a web browser.",
+  });
+
+  const result = await agent.execute({
+    instruction: "Find and click Sign In button",
+    maxSteps: 10,
+  });
+
+  console.log(result.success ? "Agent fallback success" : "Agent fallback failed");
+
+  if (!result.success) throw err;
+}
+```
+
+```python Python
+from stagehand import Stagehand
+
+try:
+    await page.act("click the 'Sign In' button")
+except Exception as err:
+    print("Agent fallback triggered")
+
+    agent = stagehand.agent({
+        "provider": "anthropic",
+        "model": "claude-sonnet-4-20250514",
+        "instructions": "Complete the action, handling any new steps required.",
+    })
+
+    result = await agent.execute({
+        "instruction": "Find and click Sign In button",

+    })

+title: 'Build a web browsing agent'
+description: 'Build an AI agent that can autonomously control a browser with Stagehand'
+---
+import { Excalidraw } from '/snippets/excalidraw.mdx';
+
+Stagehand gives AI agents powerful tools to control a browser completely autonomously. Watch below as a Stagehand agent autonomously navigates to a URL, takes actions on the page, and extracts structured data to answer a question.
+There's quite a few ways to build an agent with Stagehand. Let's look at a few of them.
+
+![Agent](/media/stagehand-agent.gif)
+
+## Stagehand MCP
+
+The above example is a Claude agent that uses Stagehand to control a browser. At this time of writing, [multimodal tool calling](https://sdk.vercel.ai/docs/ai-sdk-core/tools-and-tool-calling#multi-modal-tool-results) is only supported in Claude 3.5/3.7 Sonnet. 
+This means Claude is intelligent enough to know when to request a browser screenshot, and it can then use that screenshot to make decisions about what actions to take next.
+
+<CardGroup>
+<Card title="Browserbase MCP" href="https://github.com/browserbase/mcp-server-browserbase/" icon="hand-horns">
+Control a browser with Browserbase MCP powered by Stagehand
+</Card>
+</CardGroup>
+
+What's really interesting about this is that the agent is able to reason about the browser state and take actions separate from one another! 
+Claude is able to reason about the browser state, while Stagehand is able to take actions on the page with GPT-4o-mini or a computer use model.
+Stagehand is even smart enough to know when to use GPT-4o-mini and when to use a computer use model, i.e. on iframe detection.
+
+<Excalidraw className="w-full aspect-video" url="https://link.excalidraw.com/readonly/GWQWmWUBqMBEAamlWsIM?darkMode=true" />
+
+We've found great success from having Claude as the "Trajectory" agent calling Stagehand tools when it sees fit! 
+While MCP is really nascent, we're excited to see where it goes.
+
+## Stagehand + Computer Use Models
+
+Stagehand lets you leverage powerful computer use APIs from OpenAI and Anthropic with just one line of code. 
+
+<CodeGroup>
+```typescript TypeScript
+await page.goto("https://github.com/browserbase/stagehand");
+
+// Create a Computer Use agent with just one line of code!
+const agent = stagehand.agent({
+	provider: "openai",
+	model: "computer-use-preview"
+});
+
+// Use the agent to execute a task
+const result = await agent.execute("Extract the top contributor's username");
+console.log(result);
+```
+```python Python
+await page.goto("https://github.com/browserbase/stagehand-python")
+
+# Create a Computer Use agent with just one line of code!
+agent = stagehand.agent(
+    model="computer-use-preview"
+)
+
+# Use the agent to execute a task
+result = await agent.execute("Extract the top contributor's username")
+print(result)
+```
+</CodeGroup>

+</Card>
+</CardGroup>
+
+## Sequential Tool Calling (Open Operator)
+
+In January 2025, Browserbase released [Open Operator](https://operator.browserbase.com). 
+Open Operator is able to reason about the browser state and take actions accordingly to accomplish larger tasks like "order me a pizza".
+It works by calling Stagehand tools in sequence:
+
+1. If there's no URL, go to a default URL.
+1. Examine the browser state. Ask an LLM to reason about what to do next.
+1. Use `page.act()` to execute the LLM-suggested action.
+1. Repeat
+
+<Excalidraw className="w-full" url="https://link.excalidraw.com/readonly/dKh5sB1gEM1EjVqRCGKn" />
+
+Incorporating `stagehand.agent` into your browser automation is as easy as adding a single line of code:
+
+<Note>
+Python currently supports `stagehand.agent` with Computer Use Agent (CUA) models. The default implementation is coming soon. 
+</Note>
+
+<CodeGroup>
+```typescript TypeScript
+await stagehand.page.goto("https://github.com/browserbase/stagehand");
+
+// Open Operator will use the default LLM from Stagehand config
+const operator = stagehand.agent();
+const { message, actions } = await operator.execute(
+	"Extract the top contributor's username"
+);
+
+console.log(message);
+```
+</CodeGroup>
+
+### Replay the agent's actions
+
+You can replay the agent's actions exactly the same way you would with a regular Stagehand agent. You can even automatically cache the actions to avoid unnecessary LLM calls on a repeated run.
+
+Let's use the `replay` function below to save the actions to a Stagehand script file, which will reproduce the same actions the agent did, with cached actions built in.
+
+<Accordion title="utils.ts">
+```typescript
+import { AgentAction, AgentResult } from "@browserbasehq/stagehand";
+import { exec } from "child_process";
+import fs from "fs/promises";
+
+export async function replay(result: AgentResult) {
+  const history = result.actions;
+  const replay = history
+    .map((action: AgentAction) => {
+      switch (action.type) {
+        case "act":
+          if (!action.playwrightArguments) {
+            throw new Error("No playwright arguments provided");
+          }
+          return `await page.act(${JSON.stringify(
+            action.playwrightArguments
+          )})`;
+        case "extract":
+          return `await page.extract("${action.parameters}")`;
+        case "goto":
+          return `await page.goto("${action.parameters}")`;
+        case "wait":
+          return `await page.waitForTimeout(${parseInt(
+            action.parameters as string
+          )})`;
+        case "navback":
+          return `await page.goBack()`;
+        case "refresh":
+          return `await page.reload()`;
+        case "close":
+          return `await stagehand.close()`;
+        default:
+          return `await stagehand.oops()`;
+      }
+    })
+    .join("\n");
+
+  console.log("Replay:");
+  const boilerplate = `
+import { Page, BrowserContext, Stagehand } from "@browserbasehq/stagehand";
+
+export async function main(stagehand: Stagehand) {
+    const page = stagehand.page
+	${replay}
+}
+  `;
+  await fs.writeFile("replay.ts", boilerplate);
+
+  // Format the replay file with prettier
+  await new Promise((resolve, reject) => {
+    exec(
+      "npx prettier --write replay.ts",
+      (error: any, stdout: any, stderr: any) => {
+        if (error) {
+          console.error(`Error formatting replay.ts: ${error}`);
+          reject(error);
+          return;
+        }
+        resolve(stdout);
+      }
+    );
+  });
+}
+```
+</Accordion>
+
+Here's the replay output of an instruction like `"Get me the stock price of NVDA"`:
+
+```typescript {14-22} replay.ts
+import { Page, BrowserContext, Stagehand } from "@browserbasehq/stagehand";
+
+export async function main({
+  page,
+  context,
+  stagehand,
+}: {
+  page: Page; // Playwright Page with act, extract, and observe methods
+  context: BrowserContext; // Playwright BrowserContext
+  stagehand: Stagehand; // Stagehand instance
+}) {
+  await page.goto("https://www.google.com");
+
+  // Replay will default to Playwright first to avoid unnecessary LLM calls!
+  // If the Playwright action fails, Stagehand AI will take over and self-heal
+  await page.act({
+    description: "The search combobox where users can type their queries.",
+    method: "fill",
+    arguments: ["NVDA stock price"],

+title: Caching Actions
+description: You can cache actions in Stagehand to avoid redundant LLM calls.
+---
+
+Caching actions in Stagehand is useful for actions that are expensive to run, or when the underlying DOM structure is not expected to change.
+
+## Using `observe` to preview an action
+`observe` lets you preview an action before taking it. If you are satisfied with the action preview, you can run it in `page.act` with no further LLM calls.
+
+<CodeGroup>
+```typescript TypeScript
+const [actionPreview] = await page.observe("Click the quickstart link");
+
+/** actionPreview is a JSON-ified version of a Playwright action:
+{
+	description: "The quickstart link",
+	method: "click",
+	selector: "/html/body/div[1]/div[1]/a",
+	arguments: [],
+}
+**/
+
+// NO LLM INFERENCE when calling act on the preview
+await page.act(actionPreview)
+```
+
+```python Python
+actions = await page.observe("Click the quickstart link")
+action_preview = actions[0]
+
+# action_preview is a dictionary version of a Playwright action:
+# {
+#	"description": "The quickstart link",
+#	"method": "click",
+#	"selector": "/html/body/div[1]/div[1]/a",
+#	"arguments": [],
+# }
+
+# NO LLM INFERENCE when calling act on the preview
+await page.act(action_preview)
+```
+</CodeGroup>
+
+## Simple caching
+
+Let's use a simple file-based cache for this example. We'll write a getter and a setter functions that can read and write to a JSON file:
+
+<CodeGroup>
+```typescript TypeScript
+// Get the cached value (undefined if it doesn't exist)
+async function getCache(key: string): Promise<ObserveResult | undefined> {
+  try {
+    const cache = await readFile("cache.json");
+    const parsed = JSON.parse(cache);
+    return parsed[key];
+  } catch {
+    return undefined;
+  }
+}
+
+// Set the cache value
+async function setCache(key: string, value: ObserveResult): Promise<void> {
+  const cache = await readFile("cache.json");
+  const parsed = JSON.parse(cache);
+  parsed[key] = value;
+  await writeFile("cache.json", JSON.stringify(parsed));
+}
+```
+
+```python Python
+# Get the cached value (None if it doesn't exist)
+async def get_cache(key: str) -> Optional[Dict[str, Any]]:
+    try:
+        async with aiofiles.open("cache.json", 'r') as f:
+            cache_content = await f.read()
+            parsed = json.loads(cache_content)
+            return parsed.get(key)
+    except (FileNotFoundError, json.JSONDecodeError):
+        return None
+
+# Set the cache value
+async def set_cache(key: str, value: Dict[str, Any]) -> None:
+    try:
+        async with aiofiles.open("cache.json", 'r') as f:
+            cache_content = await f.read()
+            parsed = json.loads(cache_content)
+    except (FileNotFoundError, json.JSONDecodeError):
+        parsed = {}
+    
+    parsed[key] = value
+    
+    async with aiofiles.open("cache.json", 'w') as f:
+        await f.write(json.dumps(parsed))
+```
+</CodeGroup>
+
+### Act with cache
+Let's write a function that will check the cache, get the action, and run it. If the action fails, we'll attempt to "self-heal", i.e. retry it with `page.act` directly.
+
+<CodeGroup>
+```typescript TypeScript
+// Check the cache, get the action, and run it
+// If selfHeal is true, we'll attempt to self-heal if the action fails
+async function actWithCache(page: Page, key: string, prompt: string, selfHeal = false) {
+	try {
+		const cacheExists = await getCache(key);
+
+		let action: ObserveResult;
+		if (cacheExists) {
+		// Get the cached action
+		action = await getCache(prompt);
+		} else {
+		// Get the observe result (the action)
+		[action] = await page.observe(prompt);
+
+		// Cache the action
+		await setCache(prompt, action);
+		}
+
+		// Run the action (no LLM inference)
+		await page.act(action);
+	} catch (e) {
+		console.error(e);
+		// in selfHeal mode, we'll retry the action
+		if (selfHeal) {
+			console.log("Attempting to self-heal...");
+			await page.act(prompt);
+		}
+		else {
+			throw e;
+		}
+	}
+}
+```
+
+```python Python
+# Check the cache, get the action, and run it
+# If self_heal is true, we'll attempt to self-heal if the action fails
+async def act_with_cache(page, key: str, prompt: str, self_heal: bool = False):
+    try:
+        cache_exists = await get_cache(key)
+
+        if cache_exists:
+            # Get the cached action
+            action = await get_cache(prompt)
+        else:
+            # Get the observe result (the action)
+            actions = await page.observe(prompt)
+            action = actions[0]
+
+            # Cache the action
+            await set_cache(prompt, action)
+
+        # Run the action (no LLM inference)
+        await page.act(action)
+    except Exception as e:
+        print(f"Error: {e}")
+        # in self_heal mode, we'll retry the action
+        if self_heal:
+            print("Attempting to self-heal...")
+            await page.act(prompt)
+        else:
+            raise e
+```
+</CodeGroup>
+
+You can now use `actWithCache` to run an action with caching:
+
+<CodeGroup>
+```typescript TypeScript
+const prompt = "Click the quickstart link";
+const key = prompt; // Simple cache key
+// Attempt cached action or self-heal
+await actWithCache(page, key, prompt);
+```
+
+```python Python
+prompt = "Click the quickstart link"
+key = prompt  # Simple cache key
+# Attempt cached action or self-heal
+await act_with_cache(page, key, prompt)
+```
+</CodeGroup>
+
+## Advanced caching
+
+The above example is simple, but you may want to cache actions based on the page contents. Also, if you have duplicate prompts, you should use a more unique key.
+
+We want to leave caching logic up to you, but give you all the tools you need to implement your own caching strategy.
+
+You can directly access the DOM and accessibility tree from Playwright's page object. Here's an example of how to access the page content:
+
+<CodeGroup>
+```typescript TypeScript
+// Get the page content
+const pageContent = await page.content();
+```
+
+```python Python
+# Get the page content
+page_content = await page.content()
+```
+</CodeGroup>
+
+You may also want to use the accessibility tree, the DOM, or any other information to create a more unique key. You can do this as you please, with very similar logic to the above example.

+
+These are powerful tools that can convert natural language into actions on the computer. However, you'd otherwise need to write your own code to convert these actions into Playwright commands.

+Stagehand lets you use Computer Use Agents with one line of code:
+
+<Note>
+**IMPORTANT! Configure your browser dimensions**
+
+Computer Use Agents will often return XY-coordinates to click on the screen, so you'll need to configure your browser dimensions.
+
+If not specified, the default browser dimensions are 1024x768. You can also configure the browser dimensions in the `browserbaseSessionCreateParams` or `localBrowserLaunchOptions` options.
+</Note>
+
+
+### Configuring browser dimensions
+
+Browser configuration differs by environment:

+	// Customize the API key
+	options: {
+		apiKey: process.env.ANTHROPIC_API_KEY,
+	},
+});
+
+// Execute the agent
+await agent.execute("Apply for a library card at the San Francisco Public Library");
+```
+
+```python Python
+import os
+
+# Navigate to a website
+await stagehand.page.goto("https://www.google.com")
+
+agent = stagehand.agent({
+    # The model to use
+    model="computer-use-preview",

+
+Special thanks to [Jeremy Press](https://github.com/jeremypress), [Navid Pour](https://github.com/navidkpr), and [all the contributors](https://github.com/browserbase/stagehand/graphs/contributors) for your help in making Stagehand the best browser automation framework.
+
+***Please do not hesitate to reach out to anyone listed here in the [public Discord server](https://stagehand.dev/discord)***
+
+## General Workflow
+
+Get listed as [one of our beloved contributors](https://github.com/browserbase/stagehand/graphs/contributors)!
+
+1. **Discuss your proposed contribution before starting.** Not doing this runs you the risk of entirely discarding something you put considerable time and effort into. You can DM Miguel on [Discord](https://stagehand.dev/discord) for a 1on1 call.
+2. **Open a Pull Request.** Create a fork of this repository, and follow [GitHub’s instructions to create a Pull Request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork). This allows our team to review your contribution and leave comments. 
+3. **Wait for Review**. We'll do our best to get to your contribution as soon as possible. If it's been 2-3 days and you have yet to receive any comments, DM Miguel on [Discord](https://stagehand.dev/discord)
+4. **Merge into `evals` branch.** We don’t let external contributors [run our CI via GitHub Actions](https://github.com/browserbase/stagehand/blob/main/.github/workflows/ci.yml) to prevent spam and misuse. If your contribution passes an initial screen, we’ll run our evals on it
+    1. By default, all PRs run the following tests that you can also run from the repo source:
+        1. Lint (`npm run lint`) - Runs `prettier` and `eslint`. If this fails, you can most likely run `npm run format` to fix some simple linting errors.
+        2. Build (`npm run build`) - Lints and builds TS → JS in `dist/`
+        3. End-to-End (`npm run e2e`) - These are deterministic end-to-end Playwright tests to ensure the integrity of basic Playwright functionality of [`stagehand.page`](http://stagehand.page) and `stagehand.context` as well as compatibility with the Browserbase API
+        4. Combination (`npm run evals category combination`) - This runs AI-based end-to-end tests using combinations of `act`, `extract`, and `observe` 
+    2. If you’re changing anything about `act`, `extract`, or `observe` itself, we might also run specific act/extract/observe evals to ensure existing functionality doesn’t significantly drop.
+    
+    ![CI](/images/CI.png)
+    
+5. **Cleanup and merge to main**. Once it’s in `evals`, unfortunately the original contributor can’t make any further changes. The internal Stagehand team will be responsible for cleaning up the code and bringing it into main. 
+
+## Contribution Guidelines
+
+1. **Use draft PRs.** If your PR is a work in progress, please convert it to a draft (see below) while you’re working on it, and mark it for review/add reviewers when you’re ready. This helps us prevent clutter in the review queue.
+    
+    ![Draft PR](/images/pr_draft.png)
+    
+2. **Provide a reproducible test plan.** Include an eval (preferred) or example. We can’t merge your PR if we can’t run anything that specifically highlights your contribution. 
+    1. Write a script in [`evals/tasks`](https://github.com/browserbase/stagehand/tree/v2/evals/tasks) as `someTask.ts`
+    2. Add your script to [`evals.config.json`](https://github.com/browserbase/stagehand/blob/v2/evals/evals.config.json) with default category `combination` (*or act/extract/observe if you’re* *only* *testing* *act/extract/observe*).
+3. **Add a changeset.** Run `npx changeset` in TS or `uvx changeset` in Python to add a changeset that will directly reflect in the `CHANGELOG` in the upcoming release.
+    1. `patch` - no net new functionality to an end-user
+    2. `minor` - some net new functionality to an end-user (new function parameter, new exposed type, etc.)
+    3. `major` - you shouldn’t be committing a major change

+title: Cost Optimization  
+sidebarTitle: Cost Optimization
+description: Minimize costs while maintaining automation performance
+---
+
+Cost optimization in Stagehand involves balancing LLM inference costs and browser infrastructure costs. This guide provides practical strategies to reduce your automation expenses.
+
+## Quick Wins
+
+Start with these simple optimizations that can reduce costs:
+
+### 1. Use the Right Model for the Job
+
+We don't recommend using larger, more premium models for simple tasks. See our [evaluation results](https://stagehand.dev/evals) for model performance and cost comparisons across different task types.
+
+<CardGroup cols={2}>
+<Card title="Model Selection Guide" icon="brain" href="/v2/configuration/models">
+  Choose the right LLM for your budget and accuracy requirements
+</Card>
+<Card title="Evaluation Results" icon="chart-line" href="https://www.stagehand.dev/evals">
+  See how different models perform on different tasks
+</Card>
+</CardGroup>
+
+### 2. Implement Smart Caching
+
+Cache successful actions to avoid repeated LLM calls. Learn the basics in our [Caching Guide](/v2/best-practices/caching):
+
+<CodeGroup>
+```typescript TypeScript
+// Cache successful actions
+const [action] = await page.observe("Click the sign in button");
+await setCache("sign_in_button", action);
+
+// Reuse cached action (no LLM cost)
+const cachedAction = await getCache("sign_in_button");
+if (cachedAction) {
+  await page.act(cachedAction);
+} else {
+  await page.act(action);
+}
+```
+```python Python
+# Cache successful actions
+actions = await page.observe("Click the sign in button")
+action = actions[0]
+await set_cache("sign_in_button", action)
+
+# Reuse cached action (no LLM cost)
+cached_action = await get_cache("sign_in_button")
+if cached_action:
+    await page.act(cached_action)
+else:
+    await page.act(action)
+```
+</CodeGroup>
+
+<CardGroup cols={1}>
+<Card title="Caching Guide" icon="database" href="/v2/best-practices/caching">
+  Reduce costs with smart action caching and observe patterns
+</Card>
+</CardGroup>
+
+### 3. Optimize Browser Sessions
+
+Reuse sessions when possible and set appropriate timeouts. See [Browser Configuration](/v2/configuration/browser) for details:
+
+<CodeGroup>
+```typescript TypeScript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  browserbaseSessionCreateParams: {
+    timeout: 1800, // 30 minutes instead of default 1 hour
+    keepAlive: true, // Keep session alive between tasks
+  }
+});
+```
+```python Python
+stagehand = Stagehand(
+    env="BROWSERBASE",
+    browserbase_session_create_params={
+        "timeout": 1800,  # 30 minutes instead of default 1 hour
+        "keep_alive": True,  # Keep session alive between tasks
+    }
+)
+```
+</CodeGroup>

+<CardGroup cols={1}>
+<Card title="Browserbase Cost Optimization" icon="window-maximize" href="https://docs.browserbase.com/guides/cost-optimization">
+  Optimize Browserbase infrastructure costs and session management
+</Card>
+</CardGroup>
+
+## Advanced Strategies
+
+### Intelligent Model Switching
+
+Automatically fall back to cheaper models for simple tasks:
+
+<CodeGroup>
+```typescript TypeScript
+// Use models from least to most expensive based on task complexity
+// See stagehand.dev/evals for performance comparisons
+async function smartAct(page: Page, prompt: string) {
+  const models = ["cheaper-model", "premium-model"];
+  
+  for (const model of models) {
+    try {
+      const stagehand = new Stagehand({ modelName: model });
+      await stagehand.init();
+      const [action] = await stagehand.page.observe(prompt);
+      await stagehand.page.act(action);
+      return;
+    } catch (error) {
+      console.log(`Falling back to ${model}...`);
+    }
+  }
+}
+```
+```python Python
+# Use models from least to most expensive based on task complexity
+# See stagehand.dev/evals for performance comparisons
+async def smart_act(page, prompt: str):
+    models = ["cheaper-model", "premium-model"]
+    
+    for model in models:
+        try:
+            stagehand = Stagehand(model_name=model)
+            await stagehand.init()
+            actions = await stagehand.page.observe(prompt)
+            action = actions[0]
+            await stagehand.page.act(action)
+            return
+        except Exception:
+            print(f"Falling back to {model}...")
+```
+</CodeGroup>
+
+### Session Pooling
+
+Reuse browser sessions across multiple tasks:
+
+<CodeGroup>
+```typescript TypeScript
+class SessionManager {
+  private sessions = new Map<string, Stagehand>();
+  
+  async getSession(taskType: string): Promise<Stagehand> {
+    if (this.sessions.has(taskType)) {
+      return this.sessions.get(taskType)!;
+    }
+    
+    const stagehand = new Stagehand({ env: "BROWSERBASE" });
+    await stagehand.init();
+    this.sessions.set(taskType, stagehand);
+    return stagehand;
+  }
+}
+```
+```python Python
+class SessionManager:
+    def __init__(self):
+        self.sessions = {}
+    
+    async def get_session(self, task_type: str):
+        if task_type in self.sessions:
+            return self.sessions[task_type]
+        
+        stagehand = Stagehand(env="BROWSERBASE")
+        await stagehand.init()
+        self.sessions[task_type] = stagehand
+        return stagehand
+```
+</CodeGroup>
+
+## Cost Monitoring
+
+Track your spending to identify optimization opportunities. See our [Observability Guide](/configuration/observability) for detailed metrics:
+
+<CodeGroup>
+```typescript TypeScript
+// Monitor token usage
+const metrics = stagehand.metrics;
+console.log(`Total tokens: ${metrics.totalPromptTokens + metrics.totalCompletionTokens}`);
+console.log(`Estimated cost: $${(metrics.totalPromptTokens + metrics.totalCompletionTokens) * 0.00001}`);
+```
+```python Python
+# Monitor token usage
+metrics = stagehand.metrics
+total_tokens = metrics['total_prompt_tokens'] + metrics['total_completion_tokens']
+print(f"Total tokens: {total_tokens}")
+print(f"Estimated cost: ${total_tokens * 0.00001:.4f}")
+```
+</CodeGroup>
+
+<CardGroup cols={1}>
+<Card title="Observability & Metrics" icon="chart-line" href="/v2/configuration/observability">
+  Monitor usage patterns and track costs in real-time
+</Card>
+</CardGroup>
+
+## Budget Controls
+
+Set spending limits to prevent unexpected costs:
+
+<CodeGroup>
+```typescript TypeScript
+class BudgetGuard {
+  private dailySpend = 0;
+  private maxDailyBudget: number;
+  
+  constructor(maxDailyBudget: number = 25) {
+    this.maxDailyBudget = maxDailyBudget;
+  }
+  
+  checkBudget(estimatedCost: number): void {
+    if (this.dailySpend + estimatedCost > this.maxDailyBudget) {
+      throw new Error(`Daily budget exceeded: $${this.maxDailyBudget}`);
+    }
+    this.dailySpend += estimatedCost;
+  }
+}
+```
+```python Python
+class BudgetGuard:
+    def __init__(self, max_daily_budget: float = 25.0):
+        self.daily_spend = 0
+        self.max_daily_budget = max_daily_budget
+    
+    def check_budget(self, estimated_cost: float) -> None:
+        if self.daily_spend + estimated_cost > self.max_daily_budget:
+            raise Exception(f"Daily budget exceeded: ${self.max_daily_budget}")
+        self.daily_spend += estimated_cost
+```

+# link the current directory to a Vercel project (interactive)
+vercel link
+```
+
+### 8. Environment variables
+
+Do not commit `.env` in production. Add variables via Vercel CLI:
+
+```bash
+vercel env add BROWSERBASE_API_KEY
+vercel env add BROWSERBASE_PROJECT_ID
+# (and your model key if needed)
+vercel env add GOOGLE_API_KEY
+```
+
+See also: [Browser Environment](/configuration/environment) for details on required variables.
+
+### 9. Test locally
+
+Replicate the Vercel environment locally to exercise your Function before deploying. Run from the project root.
+
+```bash
+# ensure dependencies are installed
+npm install
+
+# start the local Vercel dev server
+vercel dev --listen 5005
+```
+
+### 10. Deploy
+
+```bash
+vercel
+vercel --prod
+```
+
+### Execute the function
+
+#### Configure Protection Bypass for Automation
+
+Before invoking the production URL, create a Protection Bypass for Automation:
+
+1. Generate a 32-character secret (you can use `openssl rand -hex 16`)
+2. Go to your project in Vercel
+3. Navigate to Settings → Deployment Protection
+4. Add the secret to "Protection Bypass for Automation"
+
+Then invoke the function with the bypass header:
+
+```bash
+curl -X POST \
+  -H "x-vercel-protection-bypass: <your-32-character-secret>" \
+  https://<your-deployment>/api/run
+```
+
+### Optional: Cron on Vercel
+
+Hit the same endpoint on a schedule by extending `vercel.json`:
+
+```json
+{
+  "$schema": "https://openapi.vercel.sh/vercel.json",
+  "functions": {
+    "api/run.ts": {
+      "maxDuration": 60
+    }
+  }
+  },
+  "crons": [
+    { "path": "/api/run", "schedule": "0 * * * *" }
+  ]
+}
+```
+
+### Features
+- **No local browsers needed** with `env: "BROWSERBASE"`. [Browserbase](https://www.browserbase.com/) provides the browsers.
+- **Fast functionality**: Offload browser work to Browserbase and return JSON promptly.
+- **Long-running tasks**: Raise `maxDuration` and/or consider Edge runtime limits depending on plan.

+title: "MCP Integrations"
+description: "Using Model Context Protocol (MCP) integrations to enhance agent capabilities"
+---
+
+## What are MCP Integrations?
+
+MCP (Model Context Protocol) integrations allow you to connect your Stagehand agents to external tools, APIs, and services. This enables agents to perform actions beyond browser automation, such as web search, database operations, and API calls.
+
+<Info>
+MCP integrations make your agents more powerful by combining browser automation with external capabilities. The agent can intelligently decide when to use browser actions versus external tools.
+</Info>
+
+## Connection Options
+
+There are two options for connecting to MCP servers:
+
+1. **Pass a URL directly** - The simplest approach for quick setup
+2. **Create a connection first** - Gives you more control over the connection
+
+<Note>
+MCP client support is currently only available in TypeScript.
+</Note>
+
+## Passing a URL
+
+The simplest way to add MCP integrations is by providing server URLs directly in the agent configuration:
+
+```typescript
+const agent = stagehand.agent({
+  provider: "openai",
+  model: "computer-use-preview",
+  integrations: [
+    `https://mcp.exa.ai/mcp?exaApiKey=${process.env.EXA_API_KEY}`,
+  ],
+  instructions: `You have access to web search through Exa. Use it to find current information before browsing.`,
+  options: {
+    apiKey: process.env.OPENAI_API_KEY,
+  },
+});
+
+await agent.execute("Search for the best headphones of 2025 and go through checkout for the top recommendation");
+```
+
+## Creating a Connection First
+
+Alternatively, you can establish MCP connections first and then pass the client objects:
+
+```typescript
+import { connectToMCPServer } from "@browserbasehq/stagehand";
+
+// Connect to MCP server
+const supabaseClient = await connectToMCPServer(
+  `https://server.smithery.ai/@supabase-community/supabase-mcp/mcp?api_key=${process.env.SMITHERY_API_KEY}`
+);
+
+// You can also pass the config to start a local MCP server
+const notionClient = await connectToMCPServer({
+  command: "npx",
+  args: ["-y", "@notionhq/notion-mcp-server"],
+  env: {
+    NOTION_TOKEN: process.env.NOTION_TOKEN,
+  },
+});
+
+// Use the connected client
+const agent = stagehand.agent({
+  provider: "openai", 
+  model: "computer-use-preview",
+  integrations: [supabaseClient, notionClient],
+  instructions: `You can interact with Supabase databases and Notion. Use these tools to store and retrieve data.`,
+  options: {
+    apiKey: process.env.OPENAI_API_KEY,
+  },
+});
+
+await agent.execute("Search for restaurants in New Brunswick, NJ and save the first result to the database");
+```
+
+
+
+## Multiple Integrations
+
+You can combine multiple MCP integrations in a single agent:
+
+```typescript
+const databaseClient = await connectToMCPServer(/* database config */);
+
+const agent = stagehand.agent({
+  integrations: [
+    `https://search-service.example.com/mcp?apiKey=${process.env.SEARCH_API_KEY}`,
+    databaseClient
+  ],
+  instructions: `You have access to external tools for search and data storage. Use these tools strategically to complete tasks efficiently.`
+});
+```
+

+
+<Tab title="Poor Instructions">
+```typescript
+instructions: "You can search and save data."
+```
+</Tab>
+</Tabs>
+
+### Error Handling
+
+Implement proper error handling for MCP connections:
+
+```typescript
+try {
+  const client = await connectToMCPServer(serverUrl);
+  
+  const agent = stagehand.agent({
+    integrations: [client],
+    // ... other config
+  });
+  
+  const result = await agent.execute(instruction);
+} catch (error) {
+  console.error("MCP integration failed:", error);
+  // Handle fallback behavior

+title: 'Playwright Interoperability'
+description: 'How Stagehand interacts with Playwright'
+---
+
+Stagehand is built on top of [Playwright](https://playwright.dev/), so you can use Playwright methods directly through the Stagehand instance.
+
+## `page` and `context`
+
+`stagehand.page` and `stagehand.context` are instances of Playwright's `Page` and `BrowserContext` respectively. Use these methods to interact with the Playwright instance that Stagehand is using.
+
+<CodeGroup>
+```TypeScript TypeScript
+const page = stagehand.page;
+// Base Playwright methods work
+await page.goto("https://github.com/browserbase/stagehand");
+
+// Stagehand overrides Playwright objects
+await page.act("click on the contributors")
+```
+
+```python Python
+page = stagehand.page
+# Base Playwright methods work
+await page.goto("https://github.com/browserbase/stagehand")
+
+# Stagehand overrides Playwright objects
+await page.act("click on the contributors")
+```
+</CodeGroup>
+
+## Stagehand v. Playwright
+Below is an example of how to extract a list of companies from the AI Grant website using both Stagehand and Playwright.
+
+<img src="/images/stagehand-playwright.png" alt="Stagehand v. Playwright" />
+
+The above example with Stagehand can be easily reused to extract data from other websites, whereas the Playwright example would need to be rewritten for each new website.

+---
+title: Prompting Best Practices
+description: "Write effective prompts for reliable Stagehand automation"
+---
+
+Good prompts make Stagehand reliable. Bad prompts cause failures. Here's how to write prompts that work consistently.
+
+## Act Method
+
+Use `act()` for single actions on web pages. Each action should be focused and clear.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Single, specific actions
+await page.act("click the 'Add to Cart' button");
+await page.act("type 'user@example.com' into the email field");
+
+// Bad - Multiple actions combined
+await page.act("fill out the form and submit it");
+await page.act("login with credentials and navigate to dashboard");
+```
+
+```python Python
+# Good - Single, specific actions
+await page.act("click the 'Add to Cart' button")
+await page.act("type 'user@example.com' into the email field")
+
+# Bad - Multiple actions combined
+await page.act("fill out the form and submit it")
+await page.act("login with credentials and navigate to dashboard")
+```
+</CodeGroup>
+
+### Use Element Types, Not Colors
+
+Describe elements by their type and function rather than visual attributes like color.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Element types and descriptive text
+await page.act("click the 'Sign In' button");
+await page.act("type into the email input field");
+
+// Bad - Color-based descriptions
+await page.act("click the blue button");
+await page.act("type into the white input");
+```
+
+```python Python
+# Good - Element types and descriptive text
+await page.act("click the 'Sign In' button")
+await page.act("type into the email input field")
+
+# Bad - Color-based descriptions
+await page.act("click the blue button")
+await page.act("type into the white input")
+```
+</CodeGroup>
+
+### Use Descriptive Language
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Clear element identification
+await page.act("click the 'Next' button at the bottom of the form");
+await page.act("type into the search bar at the top of the page");
+
+// Bad - Vague descriptions
+await page.act("click next");
+await page.act("type into search");
+```
+
+```python Python
+# Good - Clear element identification
+await page.act("click the 'Next' button at the bottom of the form")
+await page.act("type into the search bar at the top of the page")
+
+# Bad - Vague descriptions
+await page.act("click next")
+await page.act("type into search")
+```
+</CodeGroup>
+
+### Choose the Right Action Verbs
+
+- **Click** for buttons, links, checkboxes
+- **Type** for text inputs
+- **Select** for dropdowns
+- **Check/uncheck** for checkboxes
+- **Upload** for file inputs
+
+<CodeGroup>
+```typescript TypeScript
+// Good
+await page.act("click the submit button");
+await page.act("select 'Option 1' from dropdown");
+
+// Bad
+await page.act("click submit");
+await page.act("choose option 1");
+```
+
+```python Python
+# Good
+await page.act("click the submit button")
+await page.act("select 'Option 1' from dropdown")
+
+# Bad
+await page.act("click submit")
+await page.act("choose option 1")
+```
+</CodeGroup>
+
+### Protect Sensitive Data
+
+Variables keep sensitive information out of prompts and logs.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Secure approach
+await page.act({
+  action: "enter %username% in the email field",
+  variables: {
+    username: "user@example.com"
+  }
+});
+
+await page.act({
+  action: "enter %password% in the password field", 
+  variables: {
+    password: process.env.USER_PASSWORD
+  }
+});
+
+// Bad - Insecure approach
+await page.act("type 'mySecretPassword123' into the password field");
+```
+
+```python Python
+import os
+
+# Good - Secure approach
+await page.act(
+  "enter %username% in the email field",
+  variables={
+    "username": "user@example.com"
+  }
+)
+
+await page.act(
+  "enter %password% in the password field",
+  variables={
+    "password": os.environ.get("USER_PASSWORD")
+  }
+)
+
+# Bad - Insecure approach
+await page.act("type 'mySecretPassword123' into the password field")
+```
+</CodeGroup>
+
+<Warning>
+Set `verbose: 0` in your Stagehand config to prevent secrets from appearing in logs.
+</Warning>
+
+## Extract Method
+
+Use `extract()` to pull structured data from pages. Define clear schemas and provide context.
+
+### Schema Best Practices
+
+Use descriptive field names, correct types, and detailed descriptions. Field descriptions provide context that helps the agent understand exactly what to extract.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Descriptive names, correct types, and helpful descriptions
+const productData = await page.extract({
+  instruction: "Extract product information",
+  schema: z.object({
+    productTitle: z.string().describe("The main product name displayed on the page"),
+    priceInDollars: z.number().describe("Current selling price as a number, without currency symbol"),
+    isInStock: z.boolean().describe("Whether the product is available for purchase")
+  })
+});
+
+// Bad - Generic names, wrong types, no descriptions
+const data = await page.extract({
+  instruction: "Get product details", 
+  schema: z.object({
+    name: z.string(), // Too generic, no context
+    price: z.string(), // Should be number
+    stock: z.string() // Should be boolean, no context
+  })
+});
+```
+
+```python Python
+from pydantic import BaseModel, Field
+
+# Good - Descriptive names, correct types, and helpful descriptions
+class ProductData(BaseModel):
+    productTitle: str = Field(description="The main product name displayed on the page")
+    priceInDollars: float = Field(description="Current selling price as a number, without currency symbol")
+    isInStock: bool = Field(description="Whether the product is available for purchase")
+
+productData = await page.extract(
+  "Extract product information",
+  schema=ProductData
+)
+
+# Bad - Generic names, wrong types, no descriptions
+class Data(BaseModel):
+    name: str      # Too generic, no context
+    price: str     # Should be float, no context
+    stock: str     # Should be bool, no context
+
+data = await page.extract(
+  "Get product details",
+  schema=Data
+)
+```
+</CodeGroup>
+
+### Handle Arrays Correctly
+
+Always wrap schemas in objects for reliable extraction.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Array wrapped in object
+const listings = await page.extract({
+  instruction: "Extract all apartment listings",
+  schema: z.object({
+    apartments: z.array(z.object({
+      address: z.string(),
+      rent: z.number()
+    }))
+  })
+});
+
+// Bad - Bare array
+const listings = await page.extract({
+  instruction: "Extract apartment listings",
+  schema: z.array(z.string()) // Don't do this
+});
+```
+
+```python Python
+from pydantic import BaseModel
+from typing import List
+
+# Good - Array wrapped in object
+class Apartment(BaseModel):
+    address: str
+    rent: float
+
+class Listings(BaseModel):
+    apartments: List[Apartment]
+
+listings = await page.extract(
+  "Extract all apartment listings",
+  schema=Listings
+)
+
+# Bad - Bare array (not supported)
+# Don't do this - arrays must be wrapped in objects
+```
+</CodeGroup>
+
+### Use Proper URL Types
+
+Specify URL types to tell Stagehand to extract URLs. Without proper URL types, Stagehand won't extract URLs.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Tells Stagehand to extract URLs
+const links = await page.extract({
+  instruction: "Extract navigation links",
+  schema: z.object({
+    links: z.array(z.object({
+      text: z.string(),
+      url: z.string().url() // Required for URL extraction
+    }))
+  })
+});
+```
+
+```python Python
+from pydantic import BaseModel, HttpUrl
+from typing import List
+
+# Good - Tells Stagehand to extract URLs
+class Link(BaseModel):
+    text: str
+    url: HttpUrl  # Required for URL extraction
+
+class Links(BaseModel):
+    links: List[Link]
+
+links = await page.extract(
+  "Extract navigation links",
+  schema=Links
+)
+```
+</CodeGroup>
+
+## Observe Method
+
+Use `observe()` to discover actionable elements before acting on them.
+
+### Check Elements First
+
+Verify elements exist before taking action to avoid errors.
+
+<CodeGroup>
+```typescript TypeScript
+// Check for elements first
+const loginButtons = await page.observe("Find the login button");
+
+if (loginButtons.length > 0) {
+  await page.act(loginButtons[0]);
+} else {
+  console.log("No login button found");
+}
+```
+
+```python Python
+# Check for elements first
+login_buttons = await page.observe("Find the login button")
+
+if len(login_buttons) > 0:
+    await page.act(login_buttons[0])
+else:
+    print("No login button found")
+```
+</CodeGroup>
+
+### Be Specific About Element Types
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Specific element types
+const submitButtons = await page.observe("Find submit button in the form");
+const dropdowns = await page.observe("Find the state dropdown menu");
+
+// Bad - Too vague
+const elements = await page.observe("Find submit stuff");
+const things = await page.observe("Find state selection");
+```
+
+```python Python
+# Good - Specific element types
+submit_buttons = await page.observe("Find submit button in the form")
+dropdowns = await page.observe("Find the state dropdown menu")
+
+# Bad - Too vague
+elements = await page.observe("Find submit")
+things = await page.observe("Find state selection")
+```
+</CodeGroup>
+
+## Agent Method
+
+Use `agent()` for complex, multi-step workflows. Provide detailed instructions and set appropriate limits.
+
+### Navigate First
+
+Don't include navigation in agent tasks. Handle it separately.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Navigate first
+await page.goto('https://amazon.com');
+await agent.execute('Search for wireless headphones under $100 and add the best rated one to cart');
+
+// Bad - Navigation in task
+await agent.execute('Go to Amazon, search for headphones, and add one to cart');
+```
+
+```python Python
+# Good - Navigate first
+await page.goto('https://amazon.com')
+await agent.execute('Search for wireless headphones under $100 and add the best rated one to cart')
+
+# Bad - Navigation in task
+await agent.execute('Go to Amazon, search for headphones, and add one to cart')
+```
+</CodeGroup>
+
+### Be Highly Specific
+
+Detailed instructions lead to better results.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Detailed instructions
+await agent.execute({
+  instruction: "Find Italian restaurants in Brooklyn that are open after 10pm, have outdoor seating, and are rated 4+ stars. Save the top 3 results.",
+  maxSteps: 25
+});
+
+// Bad - Vague instructions
+await agent.execute("Find some good restaurants");
+```
+
+```python Python
+# Good - Detailed instructions
+await agent.execute(
+  instruction="Find Italian restaurants in Brooklyn that are open after 10pm, have outdoor seating, and are rated 4+ stars. Save the top 3 results.",
+  max_steps=25
+)
+
+# Bad - Vague instructions
+await agent.execute("Find some good restaurants")
+```
+</CodeGroup>
+
+### Set Appropriate Step Limits
+
+Match step limits to task complexity.
+
+<CodeGroup>
+```typescript TypeScript
+// Simple task - fewer steps
+await agent.execute({
+  instruction: "Subscribe to the newsletter with email 'user@example.com'",
+  maxSteps: 10
+});
+
+// Complex task - more steps  
+await agent.execute({
+  instruction: "Research and compare 5 project management tools with pricing and features",
+  maxSteps: 50
+});
+```
+
+```python Python
+# Simple task - fewer steps
+await agent.execute(
+  instruction="Subscribe to the newsletter with email 'user@example.com'",
+  max_steps=10
+)
+
+# Complex task - more steps
+await agent.execute(
+  instruction="Research and compare 5 project management tools with pricing and features",
+  max_steps=50
+)
+```
+</CodeGroup>
+
+### Include Success Criteria
+
+Tell the agent how to know when it's done.
+
+<CodeGroup>
+```typescript TypeScript
+// Good - Clear success criteria
+await agent.execute({
+  instruction: "Add 3 smartphone cases to cart and confirm the cart shows exactly 3 items with total price",
+  maxSteps: 20
+});
+
+// Bad - No validation
+await agent.execute("Add some items to cart");
+```
+
+```python Python
+# Good - Clear success criteria
+await agent.execute(
+  instruction="Add 3 smartphone cases to cart and confirm the cart shows exactly 3 items with total price",
+  max_steps=20
+)
+
+# Bad - No validation
+await agent.execute("Add some items to cart")
+```
+</CodeGroup>
+
+## Common Mistakes to Avoid
+
+- **Combining multiple actions** - Keep each `act()` call to one action
+- **Using vague descriptions** - Be specific about which elements to interact with  
+- **Exposing sensitive data** - Always use variables for credentials
+- **Skipping validation** - Check results before proceeding
+
+## Testing Your Prompts
+
+1. **Start simple** - Test basic functionality first
+2. **Add complexity gradually** - Build up to complex workflows
+3. **Monitor results** - Use logging to understand what's happening
+4. **Iterate based on failures** - Refine prompts when they don't work
+Remember: Good prompting is iterative. When in doubt, be more specific rather than less.

+sidebarTitle: Speed Optimization
+description: Optimize Stagehand performance for faster automation and reduced latency
+---
+
+Stagehand performance depends on several factors: DOM processing speed, LLM inference time, browser operations, and network latency. This guide provides proven strategies to maximize automation speed.
+
+## Quick Performance Wins
+
+### 1. Plan Ahead with Observe
+
+
+Use a single `observe()` call to plan multiple actions, then execute them efficiently:
+
+<CodeGroup>
+```typescript TypeScript
+// Instead of sequential operations with multiple LLM calls
+await page.act("Fill name field");        // LLM call #1
+await page.act("Fill email field");       // LLM call #2
+await page.act("Select country dropdown"); // LLM call #3
+
+// Use single observe to plan all form fields - one LLM call
+const formFields = await page.observe("Find all form fields to fill");
+
+// Execute all actions without LLM inference
+for (const field of formFields) {
+  await page.act(field); // No LLM calls!
+}
+```
+```python Python
+import asyncio
+
+# Instead of sequential operations with multiple LLM calls
+await page.act("Fill name field")        # LLM call #1
+await page.act("Fill email field")       # LLM call #2  
+await page.act("Select country dropdown") # LLM call #3
+
+# Use single observe to plan all form fields - one LLM call
+form_fields = await page.observe("Find all form fields to fill")
+
+# Execute all actions without LLM inference
+for field in form_fields:
+    await page.act(field) # No LLM calls!
+
+```
+</CodeGroup>
+
+<Note>
+**Performance Tip**: Acting on `observe` results avoids LLM inference entirely. This approach is 2-3x faster than direct `act()` calls and is the recommended pattern for multi-step workflows.
+</Note>

+  Learn advanced caching patterns and cache invalidation strategies
+</Card>
+
+### 2. Optimize DOM Processing
+
+Reduce DOM complexity before Stagehand processes the page:
+
+<CodeGroup>
+```typescript TypeScript
+// Remove heavy elements that slow down processing
+await page.evaluate(() => {
+  // Remove video elements
+  document.querySelectorAll('video, iframe').forEach(el => el.remove());
+  
+  // Hide complex animations
+  document.querySelectorAll('[style*="animation"]').forEach(el => {
+    (el as HTMLElement).style.animation = 'none';
+  });
+});
+
+// Then perform Stagehand operations
+await page.act("Click the submit button");
+```
+```python Python
+# Remove heavy elements that slow down processing
+await page.evaluate("""
+() => {
+  // Remove video elements
+  document.querySelectorAll('video, iframe').forEach(el => el.remove());
+  
+  // Hide complex animations
+  document.querySelectorAll('[style*="animation"]').forEach(el => {
+    el.style.animation = 'none';
+  });
+}
+""")
+
+# Then perform Stagehand operations
+await page.act("Click the submit button")
+```
+</CodeGroup>
+
+### 3. Set Appropriate Timeouts
+
+Use shorter timeouts for simple operations and longer ones for complex page loads:
+
+<CodeGroup>
+```typescript TypeScript
+// Simple actions - reduce action timeout
+await page.act({ 
+  instruction: "Click the login button",
+  actTimeout: 5000  // Default is 30000ms, reduce for simple clicks
+});
+
+// Complex page loads - optimize navigation
+await page.goto("https://heavy-spa.com", {
+  waitUntil: "domcontentloaded", // Don't wait for all resources
+  timeout: 15000 // Shorter than default 30s
+});
+```
+```python Python
+# Simple actions - reduce action timeout
+await page.act("Click button", act_timeout=5000)
+
+
+# Complex page loads - optimize navigation
+await page.goto("https://heavy-spa.com", 
+    wait_until="domcontentloaded",
+    timeout=15000
+)
+```
+</CodeGroup>
+
+## Advanced Performance Strategies
+
+
+### Smart Model Selection
+
+Use faster models for simple tasks, premium models only when needed:
+
+<CodeGroup>
+```typescript TypeScript
+class SpeedOptimizedStagehand {
+  private fastModel: Stagehand;
+  private premiumModel: Stagehand;
+
+  async smartAct(page: Page, prompt: string, complexity: 'simple' | 'complex') {
+    const model = complexity === 'simple' ? this.fastModel : this.premiumModel;
+    return await model.page.act(prompt);
+  }
+}
+
+// Use fast model for simple clicks/forms
+await stagehand.smartAct(page, "Click submit", 'simple');
+
+// Use premium model for complex reasoning
+await stagehand.smartAct(page, "Find the cheapest flight option", 'complex');
+```
+```python Python
+class SpeedOptimizedStagehand:
+    def __init__(self):
+        self.fast_model = Stagehand(model_name="fast-model")
+        self.premium_model = Stagehand(model_name="premium-model")
+    
+    async def smart_act(self, page, prompt: str, complexity: str):
+        model = self.fast_model if complexity == 'simple' else self.premium_model
+        return await model.page.act(prompt)
+
+# Use fast model for simple clicks/forms
+await stagehand.smart_act(page, "Click submit", 'simple')
+
+# Use premium model for complex reasoning  
+await stagehand.smart_act(page, "Find the cheapest flight option", 'complex')
+```
+</CodeGroup>
+
+<Card title="Model Configuration" icon="brain" href="/v2/configuration/models">
+  Compare model performance and costs
+</Card>
+
+### Page Load Optimization
+
+Skip unnecessary resources during page loads:
+
+<CodeGroup>
+```typescript TypeScript
+// Block heavy resources globally
+await context.route('**/*', (route) => {
+  const resourceType = route.request().resourceType();
+  if (['image', 'font', 'media'].includes(resourceType)) {
+    route.abort();
+  } else {
+    route.continue();
+  }
+});
+
+// Use faster navigation
+await page.goto(url, { 
+  waitUntil: 'domcontentloaded',  // Don't wait for images/fonts
+  timeout: 10000 
+});
+```
+```python Python
+# Block heavy resources globally
+async def handle_route(route):
+    resource_type = route.request.resource_type
+    if resource_type in ['image', 'font', 'media']:
+        await route.abort()
+    else:
+        await route.continue_()
+
+await context.route('**/*', handle_route)
+
+# Use faster navigation
+await page.goto(url, 
+    wait_until='domcontentloaded',  # Don't wait for images/fonts
+    timeout=10000
+)
+```

+</Card>
+
+## Performance Monitoring and Benchmarking
+
+Track performance metrics and measure optimization impact:
+
+### Performance Tracking
+
+<CodeGroup>
+```typescript TypeScript
+class PerformanceTracker {
+  private speedMetrics: Map<string, number[]> = new Map();
+
+  async timedAct(page: Page, prompt: string): Promise<ActResult> {
+    const start = Date.now();
+    const result = await page.act(prompt);
+    const duration = Date.now() - start;
+    
+    if (!this.speedMetrics.has(prompt)) {
+      this.speedMetrics.set(prompt, []);
+    }
+    this.speedMetrics.get(prompt)!.push(duration);
+    
+    console.log(`Action "${prompt}" took ${duration}ms`);
+    return result;
+  }
+
+  getAverageTime(prompt: string): number {
+    const times = this.speedMetrics.get(prompt) || [];
+    return times.reduce((a, b) => a + b, 0) / times.length;
+  }
+}
+```
+```python Python
+import time
+from collections import defaultdict
+
+class PerformanceTracker:
+    def __init__(self):
+        self.speed_metrics = defaultdict(list)
+    
+    async def timed_act(self, page, prompt: str):
+        start = time.time()
+        result = await page.act(prompt)
+        duration = (time.time() - start) * 1000  # Convert to ms
+        
+        self.speed_metrics[prompt].append(duration)
+        print(f'Action "{prompt}" took {duration:.0f}ms')
+        return result
+    
+    def get_average_time(self, prompt: str) -> float:
+        times = self.speed_metrics[prompt]
+        return sum(times) / len(times) if times else 0
+```
+</CodeGroup>
+
+Example Output:
+```
+Action "Fill form" took 1000ms
+Action "Click submit" took 2000ms
+Action "Confirm submission" took 5000ms
+```
+
+### Before vs After Benchmarking
+
+<CodeGroup>
+```typescript TypeScript
+// Before optimization
+console.time("workflow");
+await page.act("Fill form");
+await page.act("Click submit");
+await page.act("Confirm submission");
+console.timeEnd("workflow"); // 8000ms
+
+// After optimization with observe planning
+console.time("workflow-optimized");
+const workflowActions = await page.observe("Find form, submit, and confirm elements");
+
+// Execute actions sequentially to avoid conflicts
+for (const action of workflowActions) {
+  await page.act(action);
+}
+console.timeEnd("workflow-optimized"); // 500ms
+```
+```python Python
+import time
+
+# Before optimization  
+start = time.time()
+await page.act("Fill form")
+await page.act("Click submit") 
+await page.act("Confirm submission")
+print(f"Workflow took {(time.time() - start) * 1000:.0f}ms")  # 8000ms
+
+# After optimization with observe planning
+start = time.time()
+workflow_actions = await page.observe("Find form, submit, and confirm elements")
+
+# Execute actions sequentially to avoid conflicts
+for action in workflow_actions:
+    await page.act(action)
+print(f"Optimized workflow took {(time.time() - start) * 1000:.0f}ms")  # 500ms
+```
+</CodeGroup>
+
+Example Output:
+```
+Workflow took 8000ms
+Optimized workflow took 500ms

+title: 'Using Multiple Tabs'
+description: 'Act on multiple tabs with Stagehand'
+---
+
+Many modern web applications open new tabs when users click certain buttons or links. Without proper multitab support, automation scripts break when expected content appears in a new tab rather than the current one. Stagehand's multitab capabilities ensure your automations work seamlessly across multitab workflows.
+
+## The Stagehand Page
+
+Stagehand automatically adapts to multitab workflows. The `stagehand.page` object always points to the most recently opened or active tab, ensuring your automations continue working even when new tabs are created.
+
+This means you can continue using familiar patterns:
+
+<CodeGroup>
+```typescript TypeScript
+const page = stagehand.page;
+await page.goto("https://example.com");
+await page.act("click the button that opens a new tab");
+// page now automatically points to the new tab
+await page.extract("get data from new tab");
+```
+
+```python Python
+page = stagehand.page
+await page.goto("https://example.com")
+await page.act("click the button that opens a new tab")
+# page now automatically points to the new tab
+await page.extract("get data from new tab")
+```
+</CodeGroup>
+
+<Warning>
+**Important**: [Stagehand Agent](/v2/basics/agent) will always operate on the `stagehand.page`. If you need an agent to work across specific tabs, you'll need to manage page switching manually.
+</Warning>
+
+## Manual Page Management
+
+For more control or multitab workflows, you can manage multiple tabs explicitly:
+
+<CodeGroup>
+```typescript TypeScript
+// Create a second page
+await stagehand.context.newPage();
+const pages = stagehand.context.pages();
+
+const githubPage = pages[0];
+const pythonPage = pages[1];
+
+// Navigate each page to different repositories
+await githubPage.goto("https://github.com/browserbase/stagehand");
+await pythonPage.goto("https://github.com/browserbase/stagehand-python");
+
+// Extract data from both pages simultaneously
+const [stagehandStars, stagehandPythonStars] = await Promise.all([
+  githubPage.extract("extract the repository stars"),
+  pythonPage.extract("extract the repository stars")
+]);
+
+console.log(`Stagehand stars: ${stagehandStars}`);
+console.log(`Stagehand-Python stars: ${stagehandPythonStars}`);
+```
+
+```python Python
+# Create a second page
+await stagehand.context.new_page()
+pages = stagehand.context.pages()
+
+github_page = pages[0]
+python_page = pages[1]
+
+# Navigate each page to different repositories  
+await github_page.goto("https://github.com/browserbase/stagehand")
+await python_page.goto("https://github.com/browserbase/stagehand-python")
+
+# Extract data from both pages
+stagehand_stars = await github_page.extract("extract the repository stars")
+stagehand_python_stars = await python_page.extract("extract the repository stars")
+
+print(f"Stagehand stars: {stagehand_stars}")
+print(f"Stagehand-Python stars: {stagehand_python_stars}")
+```
+</CodeGroup>
+
+## Handling Tab Events
+
+You can also listen for tab events to control what happens when new tabs are opened:
+
+<CodeGroup>
+```typescript TypeScript
+const page = stagehand.page;
+await page.goto("https://browserbase.github.io/stagehand-eval-sites/sites/five-tab/");
+
+// close the new tab after it's opened
+page.on("popup", async () => {
+  const newPage = stagehand.context.pages()[1];
+  await newPage.close();
+});
+
+await page.act("click the button to open the other page");
+
+const page_number = await page.extract("extract the page number");
+console.log(`You're on page ${page_number}`);
+```
+
+```python Python
+page = stagehand.page
+await page.goto("https://browserbase.github.io/stagehand-eval-sites/sites/five-tab/")
+
+# Close the new tab after it's opened
+async def handle_popup():
+    new_page = stagehand.context.pages()[1]
+    await new_page.close()
+
+page.on("popup", handle_popup)
+
+await page.act("click the button to open the other page")
+
+page_number = await page.extract("extract the page number")
+print(f"You're on page {page_number}")
+```

+Iframes embed other pages within your current page. Sites use them for consent banners, payment widgets, chat bubbles, and third-party content.
+Elements inside iframes exist in a separate context than the main page.

+})
+```
+</CodeGroup>
+
+### Tips
+
+- Iframes can increase processing time. For best performance, use the iframe option only when necessary.
+- When you are unsure whether an element will be in an iframe, you can verify the presence of iframes in Stagehand logs.
+- If an element intermittently fails to be found, it may be inside a lazy‑loaded iframe. Add small waits between steps or re‑run your action.
+
+<Note>
+You can enable experimental features (like Shadow DOM support) via your Stagehand configuration. See the [configuration guide](/v2/configuration/browser).

+### Environment Variables
+
+Before getting started, set up the required environment variables:
+
+<CodeGroup>
+```bash .env
+BROWSERBASE_API_KEY=your_api_key_here
+BROWSERBASE_PROJECT_ID=your_project_id_here
+```
+</CodeGroup>
+
+<Tip>
+Get your API key and Project ID from the [Browserbase Dashboard](https://browserbase.com/overview)
+</Tip>
+
+### Using Stagehand with Browserbase
+
+#### Basic Setup
+
+The simplest way to get started is with default settings:
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+});
+
+await stagehand.init();
+```
+```python Python
+import os
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    env="BROWSERBASE",
+)
+
+await stagehand.init()
+```
+</CodeGroup>
+
+#### Advanced Configuration
+
+Configure browser settings, proxy support, and other session parameters:
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  // Optional: API Key and Project ID will be pulled directly from your environment
+  apiKey: process.env.BROWSERBASE_API_KEY,
+  projectId: process.env.BROWSERBASE_PROJECT_ID,
+  browserbaseSessionCreateParams: {
+    proxies: true,
+    region: "us-west-2",
+    browserSettings: {
+      viewport: { width: 1920, height: 1080 },
+      blockAds: true,
+    },
+  },
+});
+
+await stagehand.init();
+console.log("Session ID:", stagehand.sessionId);
+```
+```python Python
+import os
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    env="BROWSERBASE",
+    # Optional: API Key and Project ID will be pulled directly from your environment
+    api_key=os.getenv("BROWSERBASE_API_KEY"),
+    project_id=os.getenv("BROWSERBASE_PROJECT_ID"),

+
+### Alternative: Browserbase SDK
+
+If you prefer to manage sessions directly, you can use the Browserbase SDK:
+
+<CodeGroup>
+```typescript TypeScript
+import { Browserbase } from "@browserbasehq/sdk";
+
+const bb = new Browserbase({ 
+  apiKey: process.env.BROWSERBASE_API_KEY! 
+});
+
+const session = await bb.sessions.create({
+  projectId: process.env.BROWSERBASE_PROJECT_ID!,
+  // Add configuration options here
+});
+```
+```python Python
+from browserbase import Browserbase
+
+bb = Browserbase(api_key=os.environ["BROWSERBASE_API_KEY"])
+
+session = bb.sessions.create(
+    project_id=os.environ["BROWSERBASE_PROJECT_ID"],
+    # Add configuration options here
+)
+```
+</CodeGroup>
+
+#### Connecting to an Existing Session
+
+Connect to a previously created Browserbase session using its session ID:
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  browserbaseSessionID: "existing-session-uuid-here",
+});
+
+await stagehand.init();
+console.log("Resumed Session ID:", stagehand.sessionId);
+```
+```python Python
+import os
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    env="BROWSERBASE",
+    browserbase_session_id="existing-session-uuid-here",
+)
+
+await stagehand.init()
+print(f"Resumed Session ID: {stagehand.session_id}")
+```
+</CodeGroup>
+
+## Local Environment
+
+The local environment runs browsers directly on your machine, providing full control over browser instances and configurations. Ideal for development, debugging, and scenarios requiring custom browser setups.
+
+### Environment Comparison
+
+| Feature | Browserbase | Local |
+| --- | --- | --- |
+| **Scalability** | High (cloud-managed) | Limited (local resources) |
+| **Stealth Features** | Advanced fingerprinting | Basic stealth |
+| **Proxy Support** | Built-in residential proxies | Manual configuration |
+| **Session Persistence** | Cloud context storage | File-based user data |
+| **Geographic Distribution** | Multi-region deployment | Single machine |
+| **Debugging** | Session recordings & logs | Direct DevTools access |
+| **Setup Complexity** | Environment variables only | Browser installation required |
+| **Cost** | Usage-based pricing | Infrastructure & maintenance |
+| **Best For** | Production, scale, compliance | Development, debugging |
+
+### Basic Local Setup
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL"
+});
+  
+await stagehand.init();
+console.log("Session ID:", stagehand.sessionId);
+```
+```python Python
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    env="LOCAL"
+)
+
+await stagehand.init()
+print(f"Session ID: {stagehand.session_id}")
+```
+</CodeGroup>
+
+### Advanced Local Configuration
+
+Customize browser launch options for local development:
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  localBrowserLaunchOptions: {
+    headless: false, // Show browser window
+    devtools: true, // Open developer tools
+    viewport: { width: 1280, height: 720 },
+    executablePath: '/opt/google/chrome/chrome', // Custom Chrome path
+    args: [
+      '--no-sandbox',
+      '--disable-setuid-sandbox',
+      '--disable-web-security',
+      '--allow-running-insecure-content',
+    ],
+    env: {
+      NODE_ENV: "development",
+      DEBUG: "true",
+    },
+  },
+});
+
+await stagehand.init();
+```
+```python Python
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    env="LOCAL",
+    headless=False,  # Show browser window
+    local_browser_launch_options={
+        "devtools": True,  # Open developer tools

+            "NODE_ENV": "development",
+            "DEBUG": "true",
+        },
+    },
+)
+
+await stagehand.init()
+```
+</CodeGroup>
+
+### Connecting to your local browser
+
+Connect to your existing local Chrome/Chromium browser instead of launching a new one. This lets you automate your normal browser with all your existing tabs, extensions and settings.
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+	env: "LOCAL",
+	localBrowserLaunchOptions: {
+		cdpUrl: 'http://localhost:9222'
+	}
+});
+
+await stagehand.init();
+```
+```python Python
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    env="LOCAL",
+    local_browser_launch_options={
+      "cdp_url": "http://localhost:9222"
+    }
+)
+
+await stagehand.init()
+```
+</CodeGroup>
+

+title: Evaluations & Metrics
+sidebarTitle: Evaluations
+description: Monitor performance, optimize costs, and evaluate LLM effectiveness
+---
+
+Evaluations help you understand how well your automation performs, which models work best for your use cases, and how to optimize for cost and reliability. This guide covers both monitoring your own workflows and running comprehensive evaluations.
+
+## Why Evaluations Matter
+
+- **Performance Optimization**: Identify which models and settings work best for your specific automation tasks
+- **Cost Control**: Track token usage and inference time to optimize spending
+- **Reliability**: Measure success rates and identify failure patterns
+- **Model Selection**: Compare different LLMs on real-world tasks to make informed decisions
+
+<Card
+  title="Live Model Comparisons"
+  icon="scale-balanced"
+  href="https://www.stagehand.dev/evals"
+>
+  View real-time performance comparisons across different LLMs on the [Stagehand Evals Dashboard](https://www.stagehand.dev/evals)
+</Card>
+
+## Comprehensive Evaluations
+
+Evaluations help you systematically test and improve your automation workflows. Stagehand provides both built-in evaluations and tools to create your own.
+
+We have 2 types of evals:
+1. **Deterministic Evals** - These include unit tests, integration tests, and E2E tests that can be run without any LLM inference.
+2. **LLM-based Evals** - These are evals that test the underlying functionality of Stagehand's AI primitives.
+
+
+### Evals CLI
+![Evals CLI](/media/evals-cli.png)
+
+<Tip>
+To run evals, you'll need to clone the [Stagehand repo](https://github.com/browserbase/stagehand) and set up the CLI.
+
+We recommend using [Braintrust](https://www.braintrust.dev/docs/) to help visualize evals results and metrics.
+</Tip>
+
+The Stagehand CLI provides a powerful interface for running evaluations. You can run specific evals, categories, or external benchmarks with customizable settings.
+
+Evals are grouped into:
+1. **Act Evals** - These are evals that test the functionality of the `act` method.
+2. **Extract Evals** - These are evals that test the functionality of the `extract` method.
+3. **Observe Evals** - These are evals that test the functionality of the `observe` method.
+4. **Combination Evals** - These are evals that test the functionality of the `act`, `extract`, and `observe` methods together.
+5. **Experimental Evals** - These are experimental custom evals that test the functionality of the stagehand primitives.
+6. **Agent Evals** - These are evals that test the functionality of `agent`.
+7. **(NEW) External Benchmarks** - Run external benchmarks like WebBench, GAIA, WebVoyager, OnlineMind2Web, and OSWorld.
+
+#### Installation
+
+<Steps> 
+<Step title="Install Dependencies">
+```bash
+# From the stagehand root directory
+pnpm install
+```
+</Step>
+
+<Step title="Build the CLI">
+```bash
+pnpm run build:cli
+```
+</Step>
+
+<Step title="Verify Installation">
+```bash
+evals help
+```
+</Step>
+</Steps>
+
+#### CLI Commands and Options
+
+##### Basic Commands
+
+```bash
+# Run all evals
+evals run all
+
+# Run specific category
+evals run act
+evals run extract
+evals run observe
+evals run agent
+
+# Run specific eval
+evals run extract/extract_text
+
+# List available evals
+evals list
+evals list --detailed
+
+# Configure defaults
+evals config
+evals config set env browserbase
+evals config set trials 5
+```
+

+
+- **`-e, --env`**: Environment (`local` or `browserbase`)
+- **`-t, --trials`**: Number of trials per eval (default: 3)
+- **`-c, --concurrency`**: Max parallel sessions (default: 10)
+- **`-m, --model`**: Model override
+- **`-p, --provider`**: Provider override
+- **`--api`**: Use Stagehand API instead of SDK
+
+##### Running External Benchmarks
+
+The CLI supports several industry-standard benchmarks:
+
+```bash
+# WebBench with filters
+evals run benchmark:webbench -l 10 -f difficulty=easy -f category=READ
+
+# GAIA benchmark
+evals run b:gaia -s 100 -l 25 -f level=1
+
+# WebVoyager
+evals run b:webvoyager -l 50
+
+# OnlineMind2Web
+evals run b:onlineMind2Web
+
+# OSWorld
+evals run b:osworld -f source=Mind2Web
+```
+
+#### Configuration Files
+
+You can view the specific evals in [`evals/tasks`](https://github.com/browserbase/stagehand/tree/v2/evals/tasks). Each eval is grouped into eval categories based on [`evals/evals.config.json`](https://github.com/browserbase/stagehand/blob/main/evals/evals.config.json).
+
+
+#### Viewing eval results
+![Eval results](/images/evals.png)
+
+Eval results are viewable on Braintrust. You can view the results of a specific eval by going to the Braintrust URL specified in the terminal when you run `npm run evals`.
+
+By default, each eval will run five times per model. The "Exact Match" column shows the percentage of times the eval was correct. The "Error Rate" column shows the percentage of times the eval errored out.
+
+You can use the Braintrust UI to filter by model/eval and aggregate results across all evals.
+
+### Deterministic Evals
+
+To run deterministic evals, you can run `npm run e2e` from within the Stagehand repo. This will test the functionality of Playwright within Stagehand to make sure it's working as expected.
+
+These tests are in [`evals/deterministic`](https://github.com/browserbase/stagehand/tree/v2/evals/deterministic) and test on both Browserbase browsers and local headless Chromium browsers.
+
+## Creating Custom Evaluations
+
+### Step-by-Step Guide
+
+<Steps>
+<Step title="Create Evaluation File">
+Create a new file in `evals/tasks/your-eval.ts`:
+
+```typescript
+import { EvalTask } from '../types';
+
+export const customEvalTask: EvalTask = {
+  name: 'custom_task_name',
+  description: 'Test specific automation workflow',
+  
+  // Test setup
+  setup: async ({ page }) => {
+    await page.goto('https://example.com');
+  },
+  
+  // The actual test
+  task: async ({ stagehand, page }) => {
+    // Your automation logic
+    await page.act({ action: 'click the login button' });
+    const result = await page.extract({ 
+      instruction: 'Get the user name',
+      schema: { username: 'string' }
+    });
+    return result;
+  },
+  
+  // Validation
+  validate: (result, expected) => {
+    return result.username === expected.username;
+  },
+  
+  // Test cases
+  testCases: [
+    {
+      input: { /* test input */ },
+      expected: { username: 'john_doe' }
+    }
+  ],
+  
+  // Evaluation criteria
+  scoring: {
+    exactMatch: true,
+    timeout: 30000,
+    retries: 2
+  }
+};
+```
+</Step>
+
+<Step title="Add to Configuration">
+Update `evals/evals.config.json`:
+
+```json
+{
+  "categories": {
+    "custom": ["custom_task_name"],
+    "existing_category": ["custom_task_name"]
+  }
+}
+```
+</Step>

+title: Logging & Debugging
+sidebarTitle: Logging
+description: Set up logging, debugging, and error tracking for Stagehand workflows
+---
+
+Stagehand provides comprehensive logging capabilities to help you debug automation workflows, track execution, and diagnose issues. Configure logging levels, structured output, and debugging tools for both development and production environments.
+
+## Logging Configuration
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE", // or "LOCAL"
+  verbose: 1, // 0 = errors only, 1 = info, 2 = debug
+});
+```
+
+```python Python
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    env="BROWSERBASE",  # or "LOCAL"
+    verbose=1,  # 0 = errors only, 1 = info, 2 = debug
+)
+```
+</CodeGroup>
+
+### Verbose Levels
+
+- **Level 0**: Errors only - minimal output for production
+- **Level 1**: Info - includes successful operations and important events
+- **Level 2**: Debug - comprehensive logging including internal operations
+
+## Structured Logging
+
+### Log Line Format
+
+Each log entry contains structured information:
+
+<CodeGroup>
+```typescript TypeScript
+interface LogLine {
+  category: 'browser' | 'action' | 'llm' | 'error' | 'stagehand' | 'cache';
+  message: string;
+  level: 0 | 1 | 2; // error | info | debug
+  timestamp: string;
+  auxiliary?: {
+    executionTime?: { value: string; unit: string };
+    sessionId?: string;
+    url?: string;
+    [key: string]: any;
+  };
+}
+```
+
+```python Python
+# Log line structure in Python
+{
+  "category": "browser" | "action" | "llm" | "error" | "stagehand" | "cache",
+  "message": str,
+  "level": 0 | 1 | 2,  # error | info | debug
+  "timestamp": str,
+  "auxiliary": {
+    "execution_time": {"value": str, "unit": str},
+    "session_id": str,
+    "url": str,
+    # ... other context data
+  }
+}
+```
+</CodeGroup>
+
+### Custom Logger
+
+<CodeGroup>
+```typescript TypeScript
+class AdvancedLogger {
+  private logFile?: string;
+  
+  constructor(logFile?: string) {
+    this.logFile = logFile;
+  }

+description: Enhance Stagehand with LLMs for optimal performance, cost, and reliability
+---
+
+Stagehand uses Large Language Models (LLMs) to understand web pages, plan actions, and interact with complex interfaces. The choice of LLM significantly impacts your automation's accuracy, speed, and cost.
+
+<Card title="Model Evaluation" href="https://www.stagehand.dev/evals" icon="paper-plane">
+Find more details about how to choose the right model on our Model Evaluation page.
+</Card>
+
+## Why LLM Choice Matters
+
+- **Accuracy**: Better models provide more reliable element detection and action planning
+- **Speed**: Faster models reduce automation latency
+- **Cost**: Different providers offer varying pricing structures
+- **Reliability**: Structured output support ensures consistent automation behavior
+
+<Tip>
+Find more details about how to choose the right model on our [Model Evaluation](https://www.stagehand.dev/evals) page.
+</Tip>
+
+<Warning>
+Small models on **Ollama** struggle with consistent structured outputs. While technically supported, we don't recommend them for production Stagehand workflows.
+</Warning>
+
+## Environment Variables Setup
+
+Set up your API keys before configuring Stagehand:
+
+<CodeGroup>
+```bash .env
+# Choose one or more providers
+OPENAI_API_KEY=your_openai_key_here
+ANTHROPIC_API_KEY=your_anthropic_key_here
+GOOGLE_API_KEY=your_google_key_here
+GROQ_API_KEY=your_groq_key_here
+```
+</CodeGroup>
+
+## Supported Providers
+
+Stagehand supports major LLM providers with structured output capabilities:
+
+### Production-Ready Providers
+
+| Provider | Best Models | Strengths | Use Case |
+|----------|-------------|-----------|----------|
+| **OpenAI** | `gpt-4.1`, `gpt-4.1-mini` | High accuracy, reliable | Production, complex sites |
+| **Anthropic** | `claude-sonnet-4-6` | Excellent reasoning | Complex automation tasks |
+| **Google** | `gemini-2.5-flash`, `gemini-2.5-pro` | Fast, cost-effective | High-volume automation |
+
+### Additional Providers
+
+<Expandable title="More Providers">
+- **Groq** - `llama-3.3-70b-versatile` (Good for speed critical applications)
+- **xAI** - `grok-beta` (Good for complex reasoning)
+- **Azure** - Enterprise OpenAI deployment
+- **Cerebras** - High-speed inference
+- **TogetherAI** - Open-source models
+- **Mistral** - `mixtral-8x7b-32768` (European option)
+- **DeepSeek** - Cost-effective alternative
+- **Perplexity** - Real-time web data
+- **Ollama** - Local deployment (limited accuracy)
+- **Run any model included in AI SDK** - Find supported models in the [Vercel AI SDK](https://sdk.vercel.ai/providers/ai-sdk-providers) (Follow the guide 
+     [here](#vercel-ai-sdk) to get started.)
+</Expandable>
+
+## Basic Configuration
+
+### Model Name Format
+
+Stagehand uses the format `provider/model-name` for model specification.
+
+**Examples:**
+- OpenAI: `openai/gpt-4.1`
+- Anthropic: `anthropic/claude-sonnet-4-6`
+- Google: `google/gemini-2.5-flash` (Recommended)
+
+### Quick Start Examples
+
+<Tabs>
+<Tab title="Google (Recommended)">
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  modelName: "google/gemini-2.5-flash",
+  modelClientOptions: {
+    apiKey: process.env.GOOGLE_API_KEY,
+  },
+});
+```
+```python Python
+import os
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    model_name="google/gemini-2.5-flash",
+    model_api_key=os.getenv("GOOGLE_API_KEY")
+)
+```
+</CodeGroup>
+</Tab>
+<Tab title="OpenAI">
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  modelName: "openai/gpt-4.1",
+  modelClientOptions: {
+    apiKey: process.env.OPENAI_API_KEY,
+  },
+});
+```
+```python Python
+import os
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    model_name="openai/gpt-4.1",
+    model_api_key=os.getenv("OPENAI_API_KEY")
+)
+```
+</CodeGroup>
+</Tab>
+
+<Tab title="Anthropic">
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  modelName: "anthropic/claude-sonnet-4-6",
+  modelClientOptions: {
+    apiKey: process.env.ANTHROPIC_API_KEY,
+  },
+});
+```
+```python Python
+import os
+from stagehand import Stagehand
+
+stagehand = Stagehand(
+    model_name="anthropic/claude-sonnet-4-6",
+    model_api_key=os.getenv("ANTHROPIC_API_KEY")
+)
+```
+</CodeGroup>
+</Tab>
+</Tabs>
+
+## Custom LLM Integration
+
+<Note>
+Custom LLMs are currently only supported in TypeScript.
+</Note>
+
+Integrate any LLM with Stagehand using custom clients. The only requirement is **structured output support** for consistent automation behavior.
+
+### Vercel AI SDK
+The [Vercel AI SDK](https://sdk.vercel.ai/providers/ai-sdk-providers) is a popular library for interacting with LLMs. You can use any of the providers supported by the Vercel AI SDK to create a client for your model, **as long as they support structured outputs**.
+
+Vercel AI SDK supports providers for OpenAI, Anthropic, and Google, along with support for **Amazon Bedrock** and **Azure OpenAI**.
+
+To get started, you'll need to install the `ai` package and the provider you want to use. For example, to use Amazon Bedrock, you'll need to install the `@ai-sdk/amazon-bedrock` package.
+
+You'll also need to use the [Vercel AI SDK external client](https://github.com/browserbase/stagehand/blob/v2/examples/external_clients/aisdk.ts) as a template to create a client for your model.
+
+<Tabs>
+	<Tab title="npm">
+	```bash
+	npm install ai @ai-sdk/amazon-bedrock
+	```
+	</Tab>
+
+	<Tab title="pnpm">
+	```bash
+	pnpm install ai @ai-sdk/amazon-bedrock
+	```
+	</Tab>
+
+	<Tab title="yarn">
+	```bash
+	yarn add ai @ai-sdk/amazon-bedrock
+	```
+	</Tab>
+</Tabs>
+
+To get started, you can use the [Vercel AI SDK external client](https://github.com/browserbase/stagehand/blob/84f810b4631291307a32a47addad7e26e9c1deb3/examples/external_clients/aisdk.ts) as a template to create a client for your model.
+
+```ts
+// Install/import the provider you want to use.
+// For example, to use OpenAI, import `openai` from @ai-sdk/openai
+import { bedrock } from "@ai-sdk/amazon-bedrock";
+import { AISdkClient } from "./external_clients/aisdk";
+
+const stagehand = new Stagehand({
+  llmClient: new AISdkClient({
+	model: bedrock("anthropic.claude-sonnet-4-6-v1:0"),
+  }),
+});
+```
+
+## Troubleshooting
+
+### Common Issues
+
+<AccordionGroup>
+<Accordion title="Model doesn't support structured outputs">
+**Error**: `Model does not support structured outputs`
+
+**Solution**:
+Use models that support function calling/structured outputs. The minimum requirements are:
+
+- Model must support JSON/structured outputs
+- Model must have strong reasoning capabilities
+- Model must be able to handle complex instructions
+
+For each provider, use their latest models that meet these requirements. Some examples:
+
+- **OpenAI**: GPT-4 series or newer
+- **Anthropic**: Claude 3 series or newer 
+- **Google**: Gemini 2 series or newer
+- **Other providers**: Latest models with structured output support
+
+**Note**: Avoid base language models without structured output capabilities or fine-tuning for instruction following. When in doubt, check our [Model Evaluation](https://www.stagehand.dev/evals) page for up-to-date recommendations.
+</Accordion>
+
+<Accordion title="Authentication errors">
+**Error**: `Invalid API key` or `Unauthorized`
+
+**Solution**:
+- Verify your environment variables are set correctly
+- Check API key permissions and quotas
+- Ensure you're using the correct API key for the provider
+- For Anthropic, make sure you have access to the Claude API
+</Accordion>
+
+<Accordion title="Inconsistent automation results">
+**Symptoms**: Actions work sometimes but fail other times
+
+**Causes & Solutions**:
+- **Weak models**: Use more capable models - check our [Model Evaluation](https://www.stagehand.dev/evals) page for current recommendations
+- **High temperature**: Set temperature to 0 for deterministic outputs
+- **Complex pages**: Switch to models with higher accuracy scores on our [Model Evaluation](https://www.stagehand.dev/evals) page
+- **Rate limits**: Implement retry logic with exponential backoff
+- **Context limits**: Reduce page complexity or use models with larger context windows
+- **Prompt clarity**: Ensure your automation instructions are clear and specific
+</Accordion>
+
+<Accordion title="Slow performance">
+**Issue**: Automation takes too long to respond
+
+**Solutions**:
+- **Use fast models**: Choose models optimized for speed
+  - Any model with < 1s response time
+  - Models with "fast" or "flash" variants
+- **Optimize settings**: 
+  - Use `verbose: 0` to minimize token usage
+  - Set temperature to 0 for fastest processing
+  - Keep max tokens as low as possible
+- **Consider local deployment**: Local models can provide lowest latency
+- **Batch operations**: Group multiple actions when possible
+</Accordion>
+
+<Accordion title="High costs">
+**Issue**: LLM usage costs are too high
+
+**Cost Optimization Strategies**:
+1. **Switch to cost-effective models**: 
+   - Check our [Model Evaluation](https://www.stagehand.dev/evals) page for current cost-performance benchmarks
+   - Choose models with lower cost per token that still meet accuracy requirements
+   - Consider models optimized for speed to reduce total runtime costs
+2. **Optimize token usage**: 
+   - Set `verbose: 0` to reduce logging overhead
+   - Use concise prompts and limit response length
+3. **Smart model selection**: Start with cheaper models, fallback to premium ones only when needed
+4. **Cache responses**: Implement LLM response caching for repeated automation patterns
+5. **Monitor usage**: Set up billing alerts and track costs per automation run
+6. **Batch processing**: Process multiple similar tasks together

+
+// Query sessions by metadata
+async function querySessionsByMetadata(query: string) {
+  const sessions = await browserbase.sessions.list({
+    q: query
+  });
+  
+  return sessions;
+}
+```
+
+```python Python
+import os
+from browserbase import Browserbase
+
+browserbase = Browserbase(
+    api_key=os.getenv("BROWSERBASE_API_KEY"),
+)
+
+def get_filtered_sessions():
+    sessions = browserbase.sessions.list(status="RUNNING")
+    
+    return [{
+        'id': session['id'],
+        'status': session['status'],  # RUNNING, COMPLETED, ERROR, TIMED_OUT
+        'started_at': session['startedAt'],

+
+def query_sessions_by_metadata(query):
+    sessions = browserbase.sessions.list(q=query)
+    
+    return sessions
+```
+</CodeGroup>
+
+## Local Environment Monitoring
+
+For local development, Stagehand provides performance monitoring and resource tracking capabilities directly on your machine.
+
+### Performance Tracking
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  verbose: 1, // Monitor performance without debug noise
+});
+
+// Track local automation metrics
+const startTime = Date.now();
+const initialMetrics = stagehand.metrics;
+
+// ... perform automation tasks
+
+const finalMetrics = stagehand.metrics;
+const executionTime = Date.now() - startTime;
+
+console.log('Local Performance Summary:', {
+  executionTime: `${executionTime}ms`,
+  totalTokens: finalMetrics.totalPromptTokens + finalMetrics.totalCompletionTokens,
+  averageResponseTime: finalMetrics.totalInferenceTimeMs / 3, // Assuming 3 operations
+  tokensPerSecond: (finalMetrics.totalPromptTokens + finalMetrics.totalCompletionTokens) / (executionTime / 1000)
+});
+```
+
+```python Python
+from stagehand import Stagehand
+import time
+
+stagehand = Stagehand(
+    env="LOCAL",
+    verbose=1,  # Monitor performance without debug noise
+)
+
+# Track local automation metrics
+start_time = time.time()
+initial_metrics = stagehand.metrics
+
+# ... perform automation tasks
+
+final_metrics = stagehand.metrics
+execution_time = (time.time() - start_time) * 1000  # Convert to ms
+
+print('Local Performance Summary:', {
+    'execution_time': f"{execution_time:.0f}ms",
+    'total_tokens': final_metrics['total_prompt_tokens'] + final_metrics['total_completion_tokens'],
+    'average_response_time': final_metrics['total_inference_time_ms'] / 3,  # Assuming 3 operations
+    'tokens_per_second': (final_metrics['total_prompt_tokens'] + final_metrics['total_completion_tokens']) / (execution_time / 1000)
+})
+```
+</CodeGroup>
+
+## Resource Usage Monitoring
+
+When running locally, monitor system resource usage and browser performance:
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+import * as os from 'os';
+import { performance } from 'perf_hooks';
+
+class LocalResourceMonitor {
+  private cpuUsage: number[] = [];
+  private memoryUsage: number[] = [];
+  
+  startMonitoring() {
+    const interval = setInterval(() => {
+      // Track system resources
+      const memUsage = process.memoryUsage();
+      this.memoryUsage.push(memUsage.heapUsed / 1024 / 1024); // MB
+      
+      // Track CPU (simplified)
+      const loadAvg = os.loadavg()[0];
+      this.cpuUsage.push(loadAvg);
+    }, 1000);
+    
+    return interval;
+  }
+  
+  getResourceSummary() {
+    return {
+      avgMemoryUsage: this.memoryUsage.reduce((a, b) => a + b, 0) / this.memoryUsage.length,
+      peakMemoryUsage: Math.max(...this.memoryUsage),
+      avgCpuLoad: this.cpuUsage.reduce((a, b) => a + b, 0) / this.cpuUsage.length,

+console.log('Resource Usage:', monitor.getResourceSummary());
+```
+
+```python Python

+  </Card>
+
+
+## Real-Time Metrics & Monitoring
+
+### Basic Usage Tracking
+
+Monitor your automation's resource usage in real-time with `stagehand.metrics`:
+
+<CodeGroup>
+```typescript TypeScript
+// Get current metrics
+console.log(stagehand.metrics);
+
+// Monitor during automation
+const startTime = Date.now();
+const initialMetrics = stagehand.metrics;
+
+// ... perform automation tasks
+
+const finalMetrics = stagehand.metrics;
+const executionTime = Date.now() - startTime;
+
+console.log('Automation Summary:', {
+  totalTokens: finalMetrics.totalPromptTokens + finalMetrics.totalCompletionTokens,
+  totalCost: calculateCost(finalMetrics),
+  executionTime,
+  efficiency: (finalMetrics.totalPromptTokens + finalMetrics.totalCompletionTokens) / executionTime
+});
+```
+
+```python Python
+# Get current metrics
+print(stagehand.metrics)
+
+# Monitor during automation
+import time
+start_time = time.time()
+initial_metrics = stagehand.metrics
+
+# ... perform automation tasks
+
+final_metrics = stagehand.metrics
+execution_time = (time.time() - start_time) * 1000  # Convert to ms
+
+print('Automation Summary:', {
+    'total_tokens': final_metrics['total_prompt_tokens'] + final_metrics['total_completion_tokens'],
+    'total_cost': calculate_cost(final_metrics),
+    'execution_time': execution_time,
+    'efficiency': (final_metrics['total_prompt_tokens'] + final_metrics['total_completion_tokens']) / execution_time
+})
+```
+</CodeGroup>
+
+### Understanding Metrics Data
+
+The metrics object provides detailed breakdown by Stagehand operation:
+
+<CodeGroup>
+```typescript TypeScript
+{
+  actPromptTokens: 4011,
+  actCompletionTokens: 51,
+  actInferenceTimeMs: 1688,
+
+  extractPromptTokens: 4200,
+  extractCompletionTokens: 243,
+  extractInferenceTimeMs: 4297,
+
+  observePromptTokens: 347,
+  observeCompletionTokens: 43,
+  observeInferenceTimeMs: 903,
+
+  totalPromptTokens: 8558,
+  totalCompletionTokens: 337,
+  totalInferenceTimeMs: 6888
+}
+```
+
+```python Python
+{
+  "act_prompt_tokens": 4011,
+  "act_completion_tokens": 51,
+  "act_inference_time_ms": 1688,
+
+  "extract_prompt_tokens": 4200,
+  "extract_completion_tokens": 243,
+  "extract_inference_time_ms": 4297,
+
+  "observe_prompt_tokens": 347,
+  "observe_completion_tokens": 43,
+  "observe_inference_time_ms": 903,
+
+  "total_prompt_tokens": 8558,
+  "total_completion_tokens": 337,
+  "total_inference_time_ms": 6888
+}
+```
+</CodeGroup>
+
+### Log Inference to File
+
+You can also log inference to a file by setting `logInferenceToFile` to `true`. This will create a directory called `inference_summary` in your project's root directory.
+<CodeGroup>
+```typescript TypeScript
+const stagehand = new Stagehand({
+  logInferenceToFile: true,    
+});
+```
+
+```python Python
+stagehand = Stagehand(
+    log_inference_to_file=True,             
+)
+```
+</CodeGroup>
+The `inference_summary` directory provides granular analysis data:
+```
+inference_summary/
+├── act_summary/
+│   ├── {timestamp}.json
+│   ├── {timestamp}.json
+│   └── ...
+│   └── act_summary.json
+├── extract_summary/
+│   ├── {timestamp}.json
+│   ├── {timestamp}.json
+│   └── ...
+│   └── extract_summary.json
+├── observe_summary/
+│   ├── {timestamp}.json
+│   ├── {timestamp}.json
+│   └── ...
+│   └── observe_summary.json
+```
+
+### Log File Structure
+
+Each operation creates detailed logs for analysis:
+```typescript
+{
+  "act_summary": [
+    {
+      "act_inference_type": "act",
+      "timestamp": "20250329_080446068",
+      "LLM_input_file": "20250329_080446068_act_call.txt",
+      "LLM_output_file": "20250329_080447019_act_response.txt",
+      "prompt_tokens": 3451,
+      "completion_tokens": 45,
+      "inference_time_ms": 951
+    },
+    ...
+  ],
+}
+```

+title: AI Rules
+description: Using AI to write Stagehand code faster, and better.
+---
+
+You're likely using AI to write code, and there's a **right and wrong way to do it.** This page is a collection of rules, configs, and copy‑paste snippets to allow your AI agents/assistants to write performant, Stagehand code as fast as possible. 
+
+## Quickstart
+
+<CardGroup cols={2}>
+  <Card title="Add MCP servers" icon="screwdriver-wrench">
+    Configure Browserbase (Stagehand), Context7, DeepWiki, and Stagehand Docs in your MCP client. 
+  </Card>
+  <Card title="Pin editor rules" icon="memo">
+    Drop in `cursorrules` and `claude.md` so AI agents/assistants always emit Stagehand patterns. 
+  </Card>
+</CardGroup>
+
+## Using MCP Servers
+
+MCP (Model Context Protocol) servers act as intermediaries that connect AI systems to external data sources and tools. These servers enable your coding assistant to access real-time information, execute tasks, and retrieve structured data to enhance code generation accuracy.
+
+The following **MCP servers** provide specialized access to Stagehand documentation and related resources:
+
+<Accordion title="Context7 by Upstash" icon="database">
+Provides semantic search across documentation and codebase context. Context7 enables AI assistants to find relevant code patterns, examples, and implementation details from your project history. It maintains contextual understanding of your development workflow and can surface related solutions from previous work.
+
+**Installation:**
+```json
+{
+  "mcpServers": {
+    "context7": {
+      "command": "npx",
+      "args": ["-y", "@upstash/context7-mcp"]
+    }
+  }
+}
+```
+</Accordion>
+
+<Accordion title="DeepWiki by Cognition" icon="book-open">
+Offers deep indexing of GitHub repositories and documentation. DeepWiki allows AI agents to understand project architecture, API references, and best practices from the entire Stagehand ecosystem. It provides comprehensive knowledge about repository structure, code relationships, and development patterns.
+
+**Installation:**
+```json
+{
+  "mcpServers": {
+    "deepwiki": {
+      "url": "https://mcp.deepwiki.com/mcp"
+    }
+  }
+}
+```
+</Accordion>
+
+<Accordion title="Stagehand Docs by Mintlify" icon="mintbit">
+Direct access to official Stagehand documentation. This MCP server provides AI assistants with up-to-date API references, configuration options, and usage examples for accurate code generation. Mintlify auto-generates this server from the official docs, ensuring your AI assistant always has the latest information.
+
+**Usage:**
+```json
+{
+  "mcpServers": {
+    "stagehand-docs": {
+      "url": "https://docs.stagehand.dev/mcp"
+    }
+  }
+}
+```
+</Accordion>
+
+**How MCP Servers Enhance Your Development:**
+- **Real-time Documentation Access**: AI assistants can query the latest Stagehand docs, examples, and best practices
+- **Context-Aware Code Generation**: Servers provide relevant code patterns and configurations based on your specific use case
+- **Reduced Integration Overhead**: Standardized protocol eliminates the need for custom integrations with each documentation source
+- **Enhanced Accuracy**: AI agents receive structured, up-to-date information rather than relying on potentially outdated training data
+
+
+<Tip>
+**Prompting tip:** 
+Explicitly ask your coding agent/assistant to use these MCP servers to fetch relevant information from the docs so they have better context and know how to write proper Stagehand code. 
+
+ie. **"Use the stagehand-docs MCP to fetch the act/observe guidelines, then generate code that follows them. Prefer cached observe results."**
+</Tip>
+
+
+## Editor rule files (copy‑paste)
+
+Drop these in `.cursorrules`, `windsurfrules`, `claude.md`, or any agent rule framework:

+# Stagehand Project
+
+This is a project that uses [Stagehand](https://github.com/browserbase/stagehand), which amplifies Playwright with AI-powered `act`, `extract`, and `observe` methods added to the Page class.
+
+`Stagehand` is a class that provides configuration and browser automation capabilities with:
+- `stagehand.page`: A StagehandPage object (extends Playwright Page)
+- `stagehand.context`: A StagehandContext object (extends Playwright BrowserContext)
+- `stagehand.agent()`: Create AI-powered agents for autonomous multi-step workflows
+- `stagehand.init()`: Initialize the browser session
+- `stagehand.close()`: Clean up resources
+
+`Page` extends Playwright's Page class with AI-powered methods:
+- `act()`: Perform actions on web elements using natural language
+- `extract()`: Extract structured data from pages using schemas
+- `observe()`: Plan actions and get selectors before executing
+
+`Agent` provides autonomous Computer Use Agent capabilities:
+- `execute()`: Perform complex multi-step tasks using natural language instructions
+
+`Context` extends Playwright's BrowserContext class for browser session management.
+
+Use the following rules to write code for this project.
+
+- To plan an instruction like "click the sign in button", use Stagehand `observe` to get the action to execute.
+
+```typescript
+const results = await page.observe("Click the sign in button");
+```
+
+You can also pass in the following params:
+
+```typescript
+await page.observe({
+  instruction: "the instruction to execute",
+  returnAction: true 
+});
+```
+
+- The result of `observe` is an array of `ObserveResult` objects that can directly be used as params for `act` like this:
+  ```typescript
+  const results = await page.observe({
+    instruction: "the instruction to execute",
+    returnAction: true, // return the action to execute
+  });
+
+  await page.act(results[0]);
+  ```
+  
+- When writing code that needs to extract data from the page, use Stagehand `extract`. Explicitly pass the following params by default:
+
+```typescript
+const { someValue } = await page.extract({
+  instruction: "the instruction to execute",
+  schema: z.object({
+    someValue: z.string(),
+  }), // The schema to extract
+});
+```
+
+## Initialize
+
+```typescript
+import { Stagehand, Page, BrowserContext } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE"
+});
+
+await stagehand.init();
+
+const page = stagehand.page; // Playwright Page with act, extract, and observe methods
+
+const context = stagehand.context; // Playwright BrowserContext
+```
+### Configuration Options
+```typescript
+const StagehandConfig = {
+  env: "BROWSERBASE" | "LOCAL", // Environment to run in
+  apiKey: process.env.BROWSERBASE_API_KEY, // Browserbase API key
+  projectId: process.env.BROWSERBASE_PROJECT_ID, // Browserbase project ID
+  debugDom: true, // Enable DOM debugging features
+  headless: false, // Run browser in headless mode
+  domSettleTimeoutMs: 30_000, // Timeout for DOM to settle
+  enableCaching: true, // Enable action caching
+  modelName: "gpt-4o", // AI model to use
+  modelClientOptions: {
+    apiKey: process.env.OPENAI_API_KEY, // OpenAI API key
+  },
+};
+```
+## Act
+
+You can act directly with string instructions:
+
+```typescript
+await page.act("Click the sign in button");
+```
+
+Use variables for dynamic form filling:
+
+```typescript
+await page.act({
+  action: `Enter the following information:
+    Name: %name%
+    Email: %email%
+    Phone: %phone%`,
+  variables: {
+    name: "John Doe",
+    email: "john@example.com", 
+    phone: "+1-555-0123"
+  }
+});
+```
+
+**Best Practices:**
+- Cache the results of `observe` to avoid unexpected DOM changes
+- Keep actions atomic and specific (e.g., "Click the sign in button" not "Sign in to the website")
+- Use variable substitution for dynamic data entry
+
+Act `action` should be as atomic and specific as possible, i.e. "Click the sign in button" or "Type 'hello' into the search input".
+AVOID actions that are more than one step, i.e. "Order me pizza" or "Send an email to Paul asking him to call me".
+
+## Extract
+
+### Simple String Extraction
+
+```typescript
+const signInButtonText = await page.extract("extract the sign in button text");
+```
+
+### Structured Extraction with Schema (Recommended)
+
+Always use Zod schemas for structured data extraction:
+
+```typescript
+import { z } from "zod/v3";
+
+const data = await page.extract({
+  instruction: "extract the sign in button text",
+  schema: z.object({
+    text: z.string(),
+  }),
+});
+```
+
+### Array Extraction
+
+To extract multiple items, wrap the array in a single object:
+
+```typescript
+const data = await page.extract({
+  instruction: "extract the text inside all buttons",
+  schema: z.object({
+    buttons: z.array(z.string()),
+  })
+});
+```
+
+### Complex Object Extraction
+
+For more complex data structures:
+
+```typescript
+const productData = await page.extract({
+  instruction: "extract product information from this page",
+  schema: z.object({
+    title: z.string(),
+    price: z.number(),
+    description: z.string(),
+    features: z.array(z.string()),
+    availability: z.boolean(),
+  }),
+});
+```
+
+### Schema Validation
+
+```typescript
+import { validateZodSchema } from "./utils.js";
+import { z } from "zod/v3";
+
+const schema = z.object({ name: z.string() });
+const isValid = validateZodSchema(schema, { name: "John" }); // true
+```
+
+## Agent System
+
+Stagehand provides an Agent System for autonomous web browsing using Computer Use Agents (CUA). Agents execute multi-step workflows using natural language instructions.
+
+### Creating Agents
+
+```typescript
+// Basic agent (default)
+const agent = stagehand.agent();
+
+// OpenAI agent
+const agent = stagehand.agent({
+  provider: "openai",
+  model: "computer-use-preview",
+  instructions: "You are a helpful assistant that can use a web browser.",
+  options: { 
+    apiKey: process.env.OPENAI_API_KEY 
+  }
+});
+
+// Anthropic agent
+const agent = stagehand.agent({
+  provider: "anthropic", 
+  model: "claude-sonnet-4-20250514",
+  instructions: "You are a helpful assistant that can use a web browser.",
+  options: { 
+    apiKey: process.env.ANTHROPIC_API_KEY 
+  }
+});
+```
+### Agent Execution
+```typescript
+// Simple task
+const result = await agent.execute("Extract the title from this webpage");
+
+// Complex multi-step task
+const result = await agent.execute({
+  instruction: "Apply for the first engineer position with mock data",
+  maxSteps: 20,
+  autoScreenshot: true
+});
+```
+
+### Best Practices
+- Be specific with instructions: `"Fill out the contact form with name 'John Doe' and submit it"`
+- Break down complex tasks into smaller steps
+- Use error handling with try/catch blocks
+- Combine agents for navigation with traditional methods for precise data extraction
+
+```typescript
+// Good: Specific instructions
+await agent.execute("Navigate to products page and filter by 'Electronics'");
+
+// Avoid: Vague instructions  
+await agent.execute("Do some stuff on this page");
+```
+
+## Project Structure Best Practices
+
+- Store configurations in `stagehand.config.ts`
+- Use environment variables for API keys (see `.env.example`)
+- Implement main automation logic in functions that accept `{ page, context, stagehand }`
+- Use TypeScript with proper imports from `@browserbasehq/stagehand`

+# Stagehand Python Project
+
+This is a project that uses [Stagehand Python](https://github.com/browserbase/stagehand-python), which provides AI-powered browser automation with `act`, `extract`, and `observe` methods.
+
+`Stagehand` is a class that provides configuration and browser automation capabilities with:
+- `stagehand.page`: A StagehandPage object (extends Playwright Page)
+- `stagehand.context`: A StagehandContext object (extends Playwright BrowserContext)
+- `stagehand.agent()`: Create AI-powered agents for autonomous multi-step workflows
+- `stagehand.init()`: Initialize the browser session
+- `stagehand.close()`: Clean up resources
+
+`Page` extends Playwright's Page class with AI-powered methods:
+- `act()`: Perform actions on web elements using natural language
+- `extract()`: Extract structured data from pages using schemas
+- `observe()`: Plan actions and get selectors before executing
+
+`Agent` provides autonomous Computer Use Agent capabilities:
+- `execute()`: Perform complex multi-step tasks using natural language instructions
+
+Use the following rules to write code for this project.
+
+- To plan an instruction like "click the sign in button", use Stagehand `observe` to get the action to execute.
+
+```python
+results = await page.observe("Click the sign in button")
+```
+
+You can also pass in the following params:
+
+```python
+await page.observe(
+    instruction="the instruction to execute",
+    draw_overlay=True  # Show visual overlay on observed elements
+)
+```
+
+- The result of `observe` is a list of `ObserveResult` objects that can directly be used as params for `act` like this:
+  ```python
+  results = await page.observe("Click the sign in button")
+  await page.act(results[0])
+  ```
+- When writing code that needs to extract data from the page, use Stagehand `extract`. Use Pydantic models for schemas:
+
+```python
+from pydantic import BaseModel
+
+class ExtractedData(BaseModel):
+    some_value: str
+
+result = await page.extract(
+    instruction="the instruction to execute",
+    schema=ExtractedData
+)
+```
+
+## Initialize
+
+```python
+from stagehand import Stagehand, StagehandConfig
+import asyncio
+import os
+from dotenv import load_dotenv
+
+load_dotenv()
+
+async def main():
+    config = StagehandConfig(
+        env="BROWSERBASE",  # or "LOCAL"
+        api_key=os.getenv("BROWSERBASE_API_KEY"),
+        project_id=os.getenv("BROWSERBASE_PROJECT_ID"),
+        model_name="google/gemini-2.5-flash-preview-05-20",
+        model_api_key=os.getenv("MODEL_API_KEY"),
+    )
+    
+    # Recommended: Use as async context manager
+    async with Stagehand(config) as stagehand:
+        page = stagehand.page
+        # Your automation code here
+        
+    # Alternative: Manual initialization
+    stagehand = Stagehand(config)
+    await stagehand.init()
+    page = stagehand.page
+    # Your automation code here
+    await stagehand.close()
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+### Configuration Options
+
+Key configuration options in `StagehandConfig`:
+
+```python
+config = StagehandConfig(
+    env="BROWSERBASE",  # or "LOCAL"
+    api_key=os.getenv("BROWSERBASE_API_KEY"),
+    project_id=os.getenv("BROWSERBASE_PROJECT_ID"),
+    model_name="google/gemini-2.5-flash-preview-05-20",
+    model_api_key=os.getenv("MODEL_API_KEY"),
+    verbose=1,  # 0=minimal, 1=medium, 2=detailed
+    dom_settle_timeout_ms=30000,
+    self_heal=True,  # Enable self-healing functionality
+)
+```
+
+## Act
+
+You can act directly with string instructions:
+
+```python
+await page.act("Click the sign in button")
+```
+
+Use variables for dynamic form filling:
+
+```python
+await page.act(
+    "Enter the following information: Name: John Doe, Email: john@example.com"
+)
+```
+
+**Best Practices:**
+- Cache the results of `observe` to avoid unexpected DOM changes
+- Keep actions atomic and specific (e.g., "Click the sign in button" not "Sign in to the website")
+- Use specific, descriptive instructions
+
+Act `action` should be as atomic and specific as possible, i.e. "Click the sign in button" or "Type 'hello' into the search input".
+AVOID actions that are more than one step, i.e. "Order me pizza" or "Send an email to Paul asking him to call me".
+
+## Extract
+
+### Simple String Extraction
+```python
+sign_in_button_text = await page.extract("extract the sign in button text")
+```
+
+### Structured Extraction with Schema (Recommended)
+Always use Pydantic models for structured data extraction:
+
+```python
+from pydantic import BaseModel, Field
+from typing import List
+
+class ButtonData(BaseModel):
+    text: str = Field(..., description="Button text content")
+
+data = await page.extract(
+    instruction="extract the sign in button text",
+    schema=ButtonData
+)
+```
+
+### Array Extraction
+For arrays, use List types:
+
+```python
+from pydantic import BaseModel, Field
+from typing import List
+
+class ButtonsData(BaseModel):
+    buttons: List[str] = Field(..., description="List of button texts")
+
+data = await page.extract(
+    instruction="extract the text inside all buttons",
+    schema=ButtonsData
+)
+```
+
+### Complex Object Extraction
+For more complex data structures:
+
+```python
+from pydantic import BaseModel, Field
+from typing import List
+
+class Company(BaseModel):
+    name: str = Field(..., description="Company name")
+    description: str = Field(..., description="Brief company description")
+
+class Companies(BaseModel):
+    companies: List[Company] = Field(..., description="List of companies")
+
+companies_data = await page.extract(
+    "Extract names and descriptions of 5 companies",
+    schema=Companies
+)
+```
+
+## Agent System
+
+Stagehand provides an Agent System for autonomous web browsing using Computer Use Agents (CUA).
+
+### Creating Agents
+
+```python
+# Basic agent (uses default model)
+agent = stagehand.agent()
+
+# OpenAI agent
+agent = stagehand.agent(
+    model="computer-use-preview",
+    instructions="You are a helpful web navigation assistant.",
+    options={"apiKey": os.getenv("OPENAI_API_KEY")}
+)
+
+# Anthropic agent
+agent = stagehand.agent(
+    model="claude-sonnet-4-20250514",
+    instructions="You are a helpful web navigation assistant.",
+    options={"apiKey": os.getenv("ANTHROPIC_API_KEY")}
+)
+```
+
+### Agent Execution
+
+```python
+# Simple task
+result = await agent.execute("Play a game of 2048")
+
+# Complex multi-step task with options
+result = await agent.execute(
+    instruction="Apply for the first engineer position with mock data",
+    max_steps=20,
+    auto_screenshot=True,
+    wait_between_actions=1000  # milliseconds
+)
+```
+
+**Best Practices:**
+- Be specific with instructions: `"Fill out the contact form with name 'John Doe' and submit it"`
+- Break down complex tasks into smaller steps
+- Use error handling with try/except blocks
+- Combine agents for navigation with traditional methods for precise data extraction
+
+```python
+# Good: Specific instructions
+await agent.execute("Navigate to products page and filter by 'Electronics'")
+
+# Avoid: Vague instructions
+await agent.execute("Do some stuff on this page")
+```
+
+## Project Structure Best Practices
+
+- Store configurations in environment variables or config files
+- Use async/await patterns consistently
+- Implement main automation logic in async functions
+- Use async context managers for resource management
+- Use type hints and Pydantic models for data validation
+- Handle exceptions appropriately with try/except blocks
+``````
+
+</Accordion>
+
+## Security notes
+
+- Do not embed secrets in docs or rule files; use env vars in MCP configs.
+- Avoid broad actions that may trigger unintended navigation; prefer `observe` first.

+title: Installation
+description: Integrate Stagehand into an existing project.
+---
+
+Install Stagehand in your current app with the TypeScript or Python SDK.
+
+<Tip>
+For TypeScript/Node.js: We highly recommend using the Node.js runtime environment to run Stagehand scripts, as opposed to newer alternatives like Deno or Bun. 
+
+**Bun does not support Stagehand** since it doesn't support [Playwright](https://github.com/search?q=repo:oven-sh/bun+playwright&type=issues).
+
+For Python: We require Python 3.9+ and recommend using [uv](https://docs.astral.sh/uv/) to manage your virtual environment.

+title: Introducing Stagehand
+sidebarTitle: Introduction
+description: Developers use Stagehand to reliably automate the web.
+---
+
+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
+## The Problem with Browser Automation
+
+Traditional frameworks like Playwright and Puppeteer force you to write brittle scripts that break with every UI change. Web agents promise to solve this with AI, but leave you at the mercy of unpredictable behavior.
+
+**You're stuck between two bad options:**
+- **Too brittle**: Traditional selectors break when websites change
+- **Too agentic**: AI agents are unpredictable and impossible to debug
+
+## Enter Stagehand
+
+Stagehand gives you the best of both worlds through four powerful primitives that let you choose exactly how much AI to use:

+# Observe - Discover available actions
+actions = await page.observe("find submit buttons")
+
+# Agent - Automate entire workflows
+await agent.execute("apply for this job")
+```
+</CodeGroup>
+
+
+## Why Developers Choose Stagehand
+
+- **Precise Control**: Mix AI-powered actions with deterministic code. You decide exactly how much AI to use.
+
+- **Actually Repeatable**: Save and replay actions exactly. No more "it worked on my machine" with browser automations.
+
+- **Maintainable at Scale**: One script can automate multiple websites. When sites change, your automations adapt.
+
+- **Composable Tools**: Choose your level of automation with Act, Extract, Observe, and Agent.
+
+## Built for Modern Development
+Stagehand is designed for developers building production browser automations and AI agents that need reliable web access.

+title: Quickstart
+description: 'Stagehand allows you to build web automations with natural language and code.'
+---
+
+The quickest way to start with Stagehand is with our CLI. It scaffolds a ready‑to‑run Stagehand app with sensible defaults, and an example script. You can also try Stagehand using our [MCP server](/v2/integrations/mcp/introduction).
+
+<Note>
+This quickstart is for **TypeScript**. For **Python**, see the [installation guide](/v2/first-steps/installation).
+</Note>
+
+## 1) Create a sample project
+
+<CodeGroup>
+```bash Bash
+npx create-browser-app
+```
+</CodeGroup>
+
+## 2) Run it
+
+Follow the CLI prompts to enter the project directory and add your API keys. Then run the example script.
+
+<CodeGroup>
+```bash Bash
+cd my-stagehand-app # Enter the project directory
+cp .env.example .env  # Add your API keys
+npm start # Run the example script
+```
+</CodeGroup>
+
+## 3) Use Stagehand (act, extract, observe)
+
+The scaffold includes an index.ts file that contains the example script. Here's what it looks like:
+
+<CodeGroup>
+```typescript TypeScript
+import "dotenv/config";
+import { Stagehand } from "@browserbasehq/stagehand";
+
+async function main() {
+  const stagehand = new Stagehand({
+    env: "BROWSERBASE"
+  });
+
+  await stagehand.init();
+
+  console.log(`Stagehand Session Started`);
+  console.log(`Watch live: https://browserbase.com/sessions/${stagehand.browserbaseSessionID}`);
+
+  const page = stagehand.page;
+
+  await page.goto("https://stagehand.dev");
+
+  const extractResult = await page.extract("Extract the value proposition from the page.");
+  console.log(`Extract result:\n`, extractResult);
+
+  const actResult = await page.act("Click the 'Evals' button.");
+  console.log(`Act result:\n`, actResult);
+
+  const observeResult = await page.observe("What can I click on this page?");
+  console.log(`Observe result:\n`, observeResult);
+
+  const agent = await stagehand.agent({
+    instructions: "You're a helpful assistant that can control a web browser.",
+  });
+
+  const agentResult = await agent.execute("What is the most accurate model to use in Stagehand?");
+  console.log(`Agent result:\n`, agentResult);
+
+  await stagehand.close();
+}
+

+title: "Use CrewAI to Automate Browser Tasks"
+sidebarTitle: Configuration
+description: "Create intelligent agents that can interact with websites and automate browser tasks using natural language instructions"
+---
+
+This guide walks you through setting up CrewAI with Browserbase to create agents that can perform web automation tasks using natural language instructions.
+
+## Step 1: Install Dependencies
+
+Install the required packages for CrewAI and Stagehand integration:
+
+```bash
+pip install stagehand-py crewai crewai-tools
+```
+
+## Step 2: Configure Environment Variables
+
+You'll need API keys from three services:
+
+1. **Browserbase API Key and Project ID**: Get these from your [Browserbase dashboard](https://www.browserbase.com/)
+2. **LLM API Key**: Get an API key from [OpenAI](https://platform.openai.com/api-keys) or [Anthropic](https://console.anthropic.com/)
+
+Store your API keys securely as environment variables:
+
+```bash
+BROWSERBASE_API_KEY="your-browserbase-api-key"
+BROWSERBASE_PROJECT_ID="your-browserbase-project-id"
+OPENAI_API_KEY="your-openai-api-key"
+ANTHROPIC_API_KEY="your-anthropic-api-key"
+```
+
+## Step 3: Create Your First Agent
+
+Create a Python script with a basic CrewAI agent:
+
+```python
+import os
+from crewai import Agent, Task, Crew
+from crewai_tools import StagehandTool
+from stagehand.schemas import AvailableModel
+
+# Get API keys from environment
+browserbase_api_key = os.environ.get("BROWSERBASE_API_KEY")
+browserbase_project_id = os.environ.get("BROWSERBASE_PROJECT_ID")
+model_api_key = os.environ.get("OPENAI_API_KEY")  # or ANTHROPIC_API_KEY
+
+# Initialize the StagehandTool
+stagehand_tool = StagehandTool(
+    api_key=browserbase_api_key,
+    project_id=browserbase_project_id,
+    model_api_key=model_api_key,
+    model_name=AvailableModel.GPT_4O,  # or AvailableModel.CLAUDE_3_7_SONNET_LATEST
+)
+
+# Create an agent with the tool
+researcher = Agent(
+    role="Web Researcher",
+    goal="Find and summarize information from websites",
+    backstory="I'm an expert at finding information online.",
+    verbose=True,
+    tools=[stagehand_tool],
+)
+```
+
+## Step 4: Create and Run a Task
+
+Define a task for your agent and execute it:
+
+```python
+# Create a task that uses the tool
+research_task = Task(
+    description="Go to https://www.example.com and tell me what you see on the homepage.",
+    agent=researcher,
+)
+
+# Run the crew
+crew = Crew(
+    agents=[researcher],
+    tasks=[research_task],
+    verbose=True,
+)
+
+try:
+    result = crew.kickoff()
+    print(result)
+finally:
+    # Clean up resources
+    stagehand_tool.close()
+```
+
+## Step 5: Run Your Script
+
+Execute your Python script:
+
+```bash
+python your_crew_script.py
+```
+
+## Advanced Configuration
+
+Customize the StagehandTool behavior with additional parameters:
+
+```python
+stagehand_tool = StagehandTool(
+    api_key=browserbase_api_key,
+    project_id=browserbase_project_id, 
+    model_api_key=model_api_key,
+    model_name=AvailableModel.CLAUDE_3_7_SONNET_LATEST,
+    dom_settle_timeout_ms=5000,  # Wait longer for DOM to settle
+    headless=True,  # Run browser in headless mode
+    self_heal=True,  # Attempt to recover from errors
+    wait_for_captcha_solves=True,  # Wait for CAPTCHA solving
+    verbose=1,  # Control logging verbosity (0-3)
+)
+```
+

+description: "Automate browser tasks using natural language instructions with CrewAI"
+---
+
+## Overview
+
+This guide shows you how to use CrewAI with Browserbase to create intelligent agents that can automate web interactions. By the end of this guide, you'll know how to:
+
+- Set up CrewAI with the StagehandTool
+- Create agents that can interact with websites
+- Automate browser tasks using natural language instructions
+- Extract structured data from web pages
+
+## When You'd Use This
+
+The CrewAI integration is perfect for scenarios where you need intelligent web automation:
+
+- **Research automation**: Have agents research information across multiple websites
+- **Data collection**: Extract structured data from e-commerce sites, job boards, or news sites
+- **Form automation**: Automatically fill out and submit forms based on specific criteria
+- **Multi-step workflows**: Execute complex browser workflows that require decision-making
+
+The StagehandTool wraps the Stagehand Python SDK to provide CrewAI agents with the ability to control a real web browser and interact with websites using three core primitives:
+
+1. **Act**: Perform actions like clicking, typing, or navigating
+2. **Extract**: Extract structured data from web pages
+3. **Observe**: Identify and analyze elements on the page

+title: "LangChain JS Configuration"
+sidebarTitle: Configuration
+description: "Set up Stagehand with LangChain JS to create intelligent web automation agents"
+---
+
+This guide walks you through integrating Stagehand with LangChain JS to build powerful web automation workflows using natural language instructions.
+
+## Step 1: Install Dependencies
+
+Install the required packages for LangChain JS and Stagehand integration:
+
+```bash
+npm install @langchain/langgraph @langchain/community @langchain/core @browserbasehq/stagehand
+```
+
+## Step 2: Configure Environment Variables
+
+For remote browser automation, set up your Browserbase credentials:
+
+```bash
+BROWSERBASE_API_KEY="your-browserbase-api-key"
+BROWSERBASE_PROJECT_ID="your-browserbase-project-id"
+```
+
+## Step 3: Create a Stagehand Instance
+
+Initialize Stagehand with your preferred configuration:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+// For local development
+const stagehand = new Stagehand({
+    env: "LOCAL",
+    verbose: 2,
+    enableCaching: false,
+});
+
+// For production with Browserbase
+const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    verbose: 1,
+    enableCaching: true,
+});
+```
+
+## Step 4: Generate the StagehandToolkit
+
+Create the toolkit that provides LangChain-compatible tools:
+
+```typescript
+import { StagehandToolkit } from '@langchain/community/agents/toolkits/stagehand';
+
+const stagehandToolkit = await StagehandToolkit.fromStagehand(stagehand);
+```
+
+## Step 5: Use Individual Tools
+
+The toolkit provides four specialized tools for web automation:
+
+### Available Tools
+
+- **stagehand_navigate**: Navigate to specific URLs
+- **stagehand_act**: Perform browser actions (clicking, typing, etc.)
+- **stagehand_extract**: Extract structured data using schemas  
+- **stagehand_observe**: Analyze page elements and possible actions
+
+### Basic Tool Usage
+
+```typescript
+import { z } from "zod";
+
+// Navigate to a website
+const navigateTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_navigate"
+);
+await navigateTool.invoke("https://www.google.com");
+
+// Perform an action
+const actionTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_act"
+);
+await actionTool.invoke('Search for "OpenAI"');
+
+// Observe the page
+const observeTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_observe"
+);
+const result = await observeTool.invoke(
+    "What actions can be performed on the current page?"
+);
+console.log(JSON.parse(result));
+
+// Extract structured data
+const extractTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_extract"
+);
+const extractResult = await extractTool.invoke({
+    instruction: "Extract the main heading and description",
+    schema: z.object({
+        heading: z.string(),
+        description: z.string(),
+    }),
+});
+console.log(extractResult);
+```
+
+## Step 6: Build LangGraph Agents
+
+Integrate with LangGraph for complex automation workflows:
+
+```typescript
+import { createReactAgent } from "@langchain/langgraph/prebuilt";
+
+// Create an LLM
+const llm = new ChatOpenAI({
+    model: "gpt-4",
+    temperature: 0,
+});
+
+// Create an agent with Stagehand tools
+const agent = createReactAgent({
+    llm,
+    tools: stagehandToolkit.tools,
+});
+
+// Execute a complex workflow
+const result = await agent.invoke({
+    messages: [
+        {
+            role: "user", 
+            content: "Go to example.com, find the contact form, and extract all the form fields"
+        }
+    ]
+});
+```
+
+## Advanced Configuration
+
+### Custom Stagehand Configuration
+
+```typescript
+const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    verbose: 2,
+    enableCaching: true,
+    headless: true,
+    domSettleTimeoutMs: 5000,
+});
+```
+
+### Error Handling
+
+```typescript
+try {
+    const result = await agent.invoke({
+        messages: [{ role: "user", content: "Navigate to invalid-url.com" }]
+    });
+} catch (error) {
+    console.error("Automation failed:", error);
+} finally {
+    // Clean up resources
+    await stagehand.close();
+}
+```

+description: "AI-powered browser automation through Model Context Protocol integration with Stagehand"
+---
+
+## Overview
+
+The Browserbase MCP Server brings powerful browser automation capabilities to MCP clients through the Model Context Protocol (MCP). Built on top of [Stagehand](https://docs.stagehand.dev/), this integration provides AI-powered web automation using natural language commands.
+
+<Info>
+  The hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http)
+  endpoint is served on Browserbase infrastructure.
+  You can also run the MCP server locally with STDIO, but we recommend the
+  hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http)
+  endpoint for most users.
+</Info>
+

+  One-click installation directly in Cursor
+</Card>
+
+You can also add Browserbase MCP to Claude Code with a single command. If your client supports HTTP request headers, prefer `Authorization: Bearer YOUR_BROWSERBASE_API_KEY`; otherwise, use the legacy query-parameter fallback:
+
+```bash
+claude mcp add --transport http browserbase "https://mcp.browserbase.com/mcp?browserbaseApiKey=YOUR_BROWSERBASE_API_KEY"
+```
+
+We support both local STDIO and hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http) (SHTTP). We recommend hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http) for most users.
+
+## Endpoint

+title: Use Stagehand in Next.js
+sidebarTitle: Configuration
+description: Next.js is a popular framework for developing web-based applications in production. It powers Stagehand apps like [Brainrot](https://brainrot.run) and [Open Operator](https://operator.browserbase.com).
+---
+
+<Card
+  title="Check out the Stagehand Next.js Quickstart"
+  icon="github"
+  href="https://github.com/browserbase/stagehand-nextjs-quickstart"
+>
+  Clone our [GitHub repo](https://github.com/browserbase/stagehand-nextjs-quickstart) to get started with Stagehand in Next.js.
+</Card>
+
+## Add Stagehand to an existing Next.js project
+If you'd like to add Stagehand to an existing Next.js project, you can do so by installing the dependencies:
+<Tabs>
+	<Tab title="npm">
+	```bash
+	npm install @browserbasehq/stagehand @browserbasehq/sdk playwright zod
+	```
+	</Tab>
+
+	<Tab title="pnpm">
+	```bash
+	pnpm add @browserbasehq/stagehand @browserbasehq/sdk playwright zod
+	```
+	</Tab>
+
+	<Tab title="yarn">
+	```bash
+	yarn add @browserbasehq/stagehand @browserbasehq/sdk playwright zod
+	```
+	</Tab>
+</Tabs>
+
+### Write a server action
+Next, let's define our `main` function as a server action in `app/stagehand/main.ts`. This file will have the following three functions:
+
+1. **`main`: Run the main Stagehand script**
+2. **`runStagehand`: Initialize and run the `main` function**
+3. **`startBBSSession`: Start a Browserbase session**
+
+```ts app/stagehand/main.ts
+// 🤘 Welcome to Stagehand!
+// This file is from the [Stagehand docs](https://docs.stagehand.dev/sections/examples/nextjs).
+
+"use server";
+
+import { Stagehand } from "@browserbasehq/stagehand";
+import { z } from "zod/v3";
+import { Browserbase } from "@browserbasehq/sdk";
+
+/**
+ * Run the main Stagehand script
+ */
+async function main(stagehand: Stagehand) {
+  // You can use the `page` instance to write any Playwright code
+  // For more info: https://playwright.dev/docs/pom
+  const page = stagehand.page;
+
+  // In this example, we'll get the title of the Stagehand quickstart page
+  await page.goto("https://docs.stagehand.dev/");
+  await page.act("click the quickstart link");
+  const { title } = await page.extract({
+    instruction: "extract the main heading of the page",
+    schema: z.object({
+      title: z.string(),
+    }),
+  });
+
+  return title;
+}
+
+/**
+ * Initialize and run the main() function
+ */
+export async function runStagehand(sessionId?: string) {
+  const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    apiKey: process.env.BROWSERBASE_API_KEY,
+    projectId: process.env.BROWSERBASE_PROJECT_ID,
+    verbose: 1,
+    logger: console.log,
+    browserbaseSessionID: sessionId,
+    disablePino: true,
+  });
+  await stagehand.init();
+  await main(stagehand);
+  await stagehand.close();
+}
+
+/**
+ * Start a Browserbase session
+ */
+export async function startBBSSession() {
+  const browserbase = new Browserbase();
+  const session = await browserbase.sessions.create({
+    projectId: process.env.BROWSERBASE_PROJECT_ID!,
+  });
+  const debugUrl = await browserbase.sessions.debug(session.id);
+  return {
+    sessionId: session.id,
+    debugUrl: debugUrl.debuggerFullscreenUrl,
+  };
+}
+```
+
+### Create a client component
+Next, let's create a client component that will start a Browserbase session and run the `main` function with the server actions we just defined. We'll first create a Browserbase session and embed the session in an iframe before running the `main` function.
+
+```tsx app/components/stagehandEmbed.tsx
+"use client";
+
+import { useCallback, useState } from "react";
+import { runStagehand, startBBSSession } from "@/app/stagehand/main";
+
+export function StagehandEmbed() {
+  const [sessionId, setSessionId] = useState<string | null>(null);
+  const [debugUrl, setDebugUrl] = useState<string | null>(null);
+
+  const startSession = useCallback(async () => {
+    const { sessionId, debugUrl } = await startBBSSession();
+    setSessionId(sessionId);
+    setDebugUrl(debugUrl);
+    await runStagehand(sessionId);
+  }, []);
+
+  return (
+    <div>
+      {!sessionId && <button onClick={startSession}>Start Session</button>}
+      {sessionId && debugUrl && (
+        <iframe src={debugUrl} className="w-full h-full" />
+      )}
+    </div>
+  );
+}
+```
+
+### Use the `StagehandEmbed` component
+Now, we can use the `StagehandEmbed` component in our app.
+
+```tsx app/page.tsx
+import { StagehandEmbed } from "@/app/components/stagehandEmbed";
+
+export default function Home() {
+	return (
+		<main>
+			<StagehandEmbed />
+		</main>
+	)
+}
+```

+
+## What is `act()`?
+``` typescript
+await stagehand.act("click on add to cart")
+```
+`act` enables Stagehand to perform **individual** actions on a web page. Use it to build self-healing and deterministic automations that adapt to website changes. 
+
+## Why use `act()`?
+
+<CardGroup cols={2}>
+  <Card title="Natural Language Instructions" icon="wand-magic-sparkles" href="#using-act">

+    Cache actions to avoid LLM calls and ensure consistent execution across runs.
+  </Card>
+</CardGroup>
+
+
+## Using `act()`
+
+Use `act` to perform single actions in your automation. Here's how to click a button:
+
+```typescript
+await page.goto("https://example-store.com");
+await stagehand.act("click the add to cart button");
+```
+
+<Note>
+**iFrame and Shadow DOM Support** Stagehand automatically handles iFrame traversal and shadow DOM elements without requiring additional configuration.
+</Note>
+
+With `act`, breaking complex actions into small, single-step actions works best. If you need to orchestrate multi-step flows, use multiple `act` commands or `agent`.
+
+<Accordion title="Suggested actions">
+
+| Action | Example instruction |
+|--------|---------------------|
+| Click | `click the button` |
+| Fill | `fill the field with <value>` |
+| Type | `type <text> into the search box` |
+| Press | `press <key> in the search field` |
+| Scroll | `scroll to <position>` |
+| Select from dropdown | `select <value> from the dropdown` |
+</Accordion>
+
+### Return value of `act()`?
+When you use `act()`, Stagehand will return a `Promise<ActResult>` with the following structure:
+``` typescript
+{
+  success: true,
+  message: 'Action [click] performed successfully on selector: xpath=/html[1]/body[1]/div[1]/span[1] → Action [click] performed successfully on selector: xpath=/html[1]/body[1]/div[2]/div[1]/section[1]/div[1]/div[1]/div[25]',
+  actionDescription: 'Favorite Colour',
+  actions: [
+    {
+      selector: 'xpath=/html[1]/body[1]/div[1]/span[1]',
+      description: 'Favorite Colour',
+      method: 'click',
+      arguments: []
+    },
+    {
+      selector: 'xpath=/html[1]/body[1]/div[2]/div[1]/section[1]/div[1]/div[1]/div[25]',
+      description: 'Peach',
+      method: 'click',
+      arguments: []
+    }
+  ]
+}
+```
+
+
+<Tabs>
+<Tab title="Do this" icon="check">
+Break your task into single-step actions.
+
+```typescript
+// Break it into single-step actions
+await stagehand.act("open the filters panel");
+await stagehand.act("choose 4-star rating");
+await stagehand.act("click the apply button");
+```
+</Tab>
+
+<Tab title="Don't do this" icon="xmark">
+For multi-step tasks, use [`agent()`](/basics/agent) instead.
+
+```typescript
+// Too complex - trying to do multiple things at once
+await stagehand.act("open the filters panel, choose 4-star rating, and click apply");
+```
+</Tab>
+</Tabs>
+
+## Advanced Configuration
+
+You can pass additional options to configure the model, timeout, variables, and target page:
+
+```typescript
+// Custom model configuration
+await stagehand.act("choose 'Peach' from the favorite color dropdown", {
+  model: "google/gemini-2.5-flash",
+  timeout: 10000
+});
+```
+
+### Server-side Caching
+
+<Note>
+`serverCache` only works when running with `env: "BROWSERBASE"`. It has no effect in local environments.
+</Note>
+
+When running on Browserbase, Stagehand automatically caches `act()` results server-side. Repeated calls with the same inputs return instantly without consuming LLM tokens. Caching is enabled by default and can be controlled globally on the constructor or overridden per call:
+
+```typescript
+// Disable server-side caching for the entire instance
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  serverCache: false,
+});
+
+// Or disable it for a single call
+await stagehand.act("click the login button", { serverCache: false });
+
+// Check whether a result was served from cache
+const result = await stagehand.act("click the login button");
+console.log(result.cacheStatus); // "HIT", "MISS", or undefined
+```
+
+### Using with Custom Pages
+
+You can use `act()` with pages from other browser automation libraries like Puppeteer, Playwright, or Patchright by passing the `page` option:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import puppeteer from "puppeteer-core";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+});
+await stagehand.init();
+
+// Connect with Puppeteer
+const browser = await puppeteer.connect({
+  browserWSEndpoint: stagehand.connectURL(),
+  defaultViewport: null,
+});
+
+const pages = await browser.pages();
+const customPage = pages[0];
+
+await customPage.goto("https://www.example.com/blog");
+
+// Use act with the custom Puppeteer page
+await stagehand.act("click the next page button", {
+  page: customPage
+});
+```
+
+This works with:
+- **Puppeteer**: Pass Puppeteer Page objects
+- **Playwright**: Pass Playwright Page objects
+- **Patchright**: Pass Patchright Page objects
+- **Stagehand Page**: Use `stagehand.context.pages()[0]` or `context.activePage()` (default)
+

+  See the full `act()` reference for detailed parameter documentation, return values, and advanced examples.
+</Card>
+
+
+
+
+
+## Best practices
+
+### Ensure reliable actions
+
+Use `observe()` to discover candidate actions on the current page and plan reliably. It returns a list of suggested actions (with selector, description, method, and arguments). You can pass an observed action directly to `act` to execute it.
+
+```typescript
+const [action] = await stagehand.observe("click the login button");
+
+if (action) {
+  await stagehand.act(action);
+}
+```
+
+<Card title="Analyze pages with observe()" icon="magnifying-glass" iconType="sharp-solid" href="/v3/basics/observe">
+  Plan actions with `observe()` before executing with `act`.
+</Card>
+
+### Reduce model costs
+
+Enable automatic action caching by specifying a `cacheDir` when initializing Stagehand. The first time an action runs, it's cached. Subsequent runs reuse the cached action without LLM calls.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+// Enable caching by specifying a cache directory
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "act-cache" // Actions are automatically cached here
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+// First run - makes LLM call and caches the action
+await stagehand.act("click the login button");
+```
+
+<Note>
+Caching persists across script executions. The first time you run your script, actions are cached to your local filesystem. On subsequent runs, cached actions are reused automatically, significantly reducing costs and improving performance.
+</Note>
+
+<Card title="Complete caching guide" icon="database" iconType="sharp-solid" href="/v3/best-practices/caching">
+  Learn advanced caching techniques and patterns for optimal performance.
+</Card>
+
+### Secure your automations
+
+Variables are **not shared with LLM providers**. Use them for passwords, API keys, and other sensitive data.
+
+<Note>
+Load sensitive data from environment variables using `.env` files. Never hardcode API keys, passwords, or other secrets directly in your code.
+</Note>
+
+```typescript
+// Variables use %variableName% syntax in the instruction
+await stagehand.act("type %username% into the email field", {
+  variables: { username: "user@example.com" }
+});
+
+await stagehand.act("type %password% into the password field", {
+  variables: { password: process.env.USER_PASSWORD }
+});
+
+await stagehand.act("click the login button");
+```
+
+<Warning>
+When handling sensitive data, set `verbose: 0` in your Stagehand configuration to prevent secrets from appearing in logs. See the [configuration guide](/configuration/browser) for more details.

+
+## Troubleshooting
+
+<AccordionGroup>
+
+
+<Accordion title="Method not supported">
+**Problem**: `act` fails with "method not supported" error
+
+**Solutions**:
+- Use clear and detailed instructions for what you want to accomplish
+- Review our [evals](https://stagehand.dev/evals) to find the best models for your use case
+- Use [`observe()`](/basics/observe) and verify the resulting action is within a list of expected actions
+
+**Solution 1: Validate with observe**
+
+```typescript
+const prompt = "click the submit button";
+const expectedMethod = "click";
+
+try {
+  await stagehand.act(prompt);
+} catch (error) {
+  if (error.message.includes("method not supported")) {
+    // Observe the same prompt to get the planned action
+    const [action] = await stagehand.observe(prompt);
+
+    if (action && action.method === expectedMethod) {
+      await stagehand.act(action);
+    } else {
+      throw new Error(`Unsupported method: expected "${expectedMethod}", got "${action?.method}"`);
+    }
+  } else {
+    throw error;
+  }
+}
+```
+
+**Solution 2: Retry with exponential backoff**
+
+```typescript
+// Retry with exponential backoff for intermittent issues
+const prompt = "click the submit button";
+const maxRetries = 3;
+
+for (let attempt = 0; attempt <= maxRetries; attempt++) {
+  try {
+    await stagehand.act(prompt, { timeout: 10000 + (attempt * 5000) });
+    break; // Success, exit retry loop
+  } catch (error) {
+    if (error.message.includes("method not supported") && attempt < maxRetries) {
+      // Exponential backoff: wait 2^attempt seconds
+      const delay = Math.pow(2, attempt) * 1000;
+      console.log(`Retry ${attempt + 1}/${maxRetries} after ${delay}ms`);
+      await new Promise(resolve => setTimeout(resolve, delay));
+    } else {
+      throw error;
+    }
+  }
+}
+```
+
+</Accordion>
+
+<Accordion title="Action failed or timed out">
+**Problem**: `act` times out or fails to complete action (often due to element not found)
+
+**Solutions**:
+- Ensure page has fully loaded
+- Check if content is in iframes: [Learn more about working with iframes](/best-practices/working-with-iframes)
+- Increase action timeout
+- Use `observe()` first to verify element exists
+
+```typescript
+// Handle timeout and element not found issues
+try {
+  await stagehand.act("click the submit button", { timeout: 30000 });
+} catch (error) {
+  // Check if page is fully loaded
+  await page.waitForLoadState('domcontentloaded');
+
+  // Use observe to check element state
+  const [element] = await stagehand.observe("find the submit button");
+
+  if (element) {
+    console.log("Element found, trying more specific instruction");
+    await stagehand.act("click the submit button at the bottom of the form");
+  } else {
+    console.log("Element not found, trying alternative selector");
+    await stagehand.act("click the button with text 'Submit'");
+  }
+}
+```
+</Accordion>
+
+<Accordion title="Incorrect element selected">
+**Problem**: `act` performs action on wrong element
+
+**Solutions**:
+- Be more specific in instructions: include visual cues, position, or context
+- Use `observe()` to preview which element will be selected
+- Add contextual information: "the search button in the header"
+- Use unique identifiers when available
+
+```typescript
+// More precise element targeting
+// Instead of:
+await stagehand.act("click the button");
+
+// Use specific context:
+await stagehand.act("click the red 'Delete' button next to the user John Smith");
+
+// Or preview with observe first:
+const [action] = await stagehand.observe("click the submit button in the checkout form");
+if (action.description.includes("checkout")) {
+  await stagehand.act(action);
+}
+```

+
+### Computer Use Agents
+
+You can use specialized computer use models from Google, OpenAI, Anthropic, or Microsoft as shown below, with `mode` set to `"cua"`. To compare the performance of different computer use models, you can visit our [evals page](https://www.stagehand.dev/agent-evals).
+
+<Warning>
+**Deprecation Notice:** The `cua: true` option is deprecated and will be removed in a future version. Use `mode: "cua"` instead.
+</Warning>
+
+<CodeGroup>
+```typescript Google
+const agent = stagehand.agent({
+    mode: "cua",
+    model: "google/gemini-3-flash-preview",
+    systemPrompt: "You are a helpful assistant...",
+});
+
+await agent.execute({
+    instruction: "Go to Hacker News and find the most controversial post from today, then read the top 3 comments and summarize the debate.",
+    maxSteps: 20,
+    highlightCursor: true
+})
+```
+
+```typescript OpenAI
+const agent = stagehand.agent({
+    mode: "cua",
+    model: "openai/computer-use-preview",
+    systemPrompt: "You are a helpful assistant...",
+});
+
+await agent.execute({
+    instruction: "Go to Hacker News and find the most controversial post from today, then read the top 3 comments and summarize the debate.",
+    maxSteps: 20,
+    highlightCursor: true
+})
+```
+```typescript Anthropic
+const agent = stagehand.agent({
+    mode: "cua",
+    model: "anthropic/claude-sonnet-4-6",
+    systemPrompt: "You are a helpful assistant...",
+});
+
+await agent.execute({
+    instruction: "Go to Hacker News and find the most controversial post from today, then read the top 3 comments and summarize the debate.",
+    maxSteps: 20,

+
+### Use Stagehand Agent with Any LLM
+
+Use the agent without specifying a provider to utilize any model or LLM provider:
+
+<Note>Non CUA agents are currently only supported in TypeScript</Note>
+
+```typescript TypeScript
+const agent = stagehand.agent();
+await agent.execute("apply for a job at Browserbase")
+```
+<Card title="Available Agent Models" icon="robot" href="/v3/configuration/models#agent-models-with-cua-support">
+  Check out the guide on how to use different models with Stagehand Agent.
+</Card>
+
+### Hybrid Mode
+
+Both DOM and CUA modes have their strengths and weaknesses. Hybrid mode combines them, giving the agent access to both coordinate-based and DOM-based tools to better account for where each may fall short.
+
+<Warning>
+**Model Requirements:** Hybrid mode requires models that can reliably perform coordinate-based actions from screenshots. The following models are recommended:
+- **Anthropic:** any Claude model (e.g. `anthropic/claude-sonnet-4-6`, `anthropic/claude-haiku-4-5-20251001`)
+- **OpenAI:** `openai/gpt-5.4`, `openai/gpt-5.4-mini`
+- **Google:** `google/gemini-3-flash-preview`, `google/gemini-3.1-flash-lite-preview`, `google/gemini-3.1-pro-preview`
+
+Other models may not reliably produce accurate coordinates for clicking and typing.
+
+</Warning>
+
+<Note>Hybrid mode requires `experimental: true` in your Stagehand constructor.</Note>
+
+<CodeGroup>
+```typescript Hybrid Mode with Google
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  experimental: true, // Required for hybrid mode
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  mode: "hybrid",
+  model: "google/gemini-3-flash-preview",
+});
+
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+
+await agent.execute({
+  instruction: "Click the sign up button and fill out the registration form",
+  maxSteps: 20,
+});
+```
+
+```typescript Hybrid Mode with Anthropic
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  experimental: true, // Required for hybrid mode
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  mode: "hybrid",
+  model: "anthropic/claude-haiku-4-5-20251001",
+  systemPrompt: "You are a helpful assistant that interacts with web pages visually.",
+});
+
+await agent.execute({
+  instruction: "Navigate the page and interact with the form elements",
+  maxSteps: 15,
+  highlightCursor: true, // Enabled by default in hybrid mode
+});
+```
+</CodeGroup>
+
+### Return value of `agent()`?
+
+When you use `agent()`, Stagehand will return a `Promise<AgentResult>` with the following structure:
+
+```typescript

+
+## Customizing Agent Tools
+
+Stagehand agents come with built-in tools for browser automation, but you can customize the toolset by adding your own custom tools or excluding built-in ones.
+
+### Adding Custom Tools
+
+Custom tools enhance agents with additional capabilities for more granular control and better performance. Unlike MCP integrations, custom tools are defined inline and execute directly within your application.
+
+<Note>Custom tools provide a cleaner, more performant alternative to MCP integrations when you need specific functionality.</Note>
+
+#### Defining Custom Tools
+
+Use the `tool` helper exported from `@browserbasehq/stagehand` to define custom tools:
+
+<CodeGroup>
+```typescript Basic Tool
+import { tool } from "@browserbasehq/stagehand";
+import { z } from "zod";
+
+const agent = stagehand.agent({
+  model: "openai/gpt-5",
+  tools: {
+    getWeather: tool({
+      description: 'Get the current weather in a location',
+      inputSchema: z.object({
+        location: z.string().describe('The location to get weather for'),
+      }),
+      execute: async ({ location }) => {
+        // Your custom logic here
+        const weather = await fetchWeatherAPI(location);
+        return {
+          location,
+          temperature: weather.temp,
+          conditions: weather.conditions,
+        };
+      },
+    }),
+  },
+  systemPrompt: 'You are a helpful assistant with access to weather data.',
+});
+
+await agent.execute("What's the weather in San Francisco and should I bring an umbrella?");
+```
+
+```typescript Multiple Tools
+import { tool } from "@browserbasehq/stagehand";
+import { z } from "zod";
+
+const agent = stagehand.agent({
+  mode: "cua",
+  model: "anthropic/claude-sonnet-4-6",
+  tools: {
+    searchDatabase: tool({
+      description: 'Search for records in the database',
+      inputSchema: z.object({
+        query: z.string().describe('The search query'),
+        limit: z.number().optional().describe('Max results to return'),
+      }),
+      execute: async ({ query, limit = 10 }) => {
+        const results = await db.search(query, limit);
+        return { results };
+      },
+    }),
+
+    calculatePrice: tool({
+      description: 'Calculate the total price with tax',
+      inputSchema: z.object({
+        amount: z.number().describe('The base amount'),
+        taxRate: z.number().describe('Tax rate as decimal (e.g., 0.08 for 8%)'),
+      }),
+      execute: async ({ amount, taxRate }) => {
+        const total = amount * (1 + taxRate);
+        return { total: total.toFixed(2) };
+      },
+    }),
+  },
+});
+
+await agent.execute("Find products under $50 and calculate the total with 8% tax");
+```
+
+```typescript Tool with API Integration
+import { tool } from "@browserbasehq/stagehand";
+import { z } from "zod";
+
+const agent = stagehand.agent({
+  model: "google/gemini-2.0-flash",
+  tools: {
+    sendEmail: tool({
+      description: 'Send an email via SendGrid',
+      inputSchema: z.object({
+        to: z.string().email().describe('Recipient email address'),
+        subject: z.string().describe('Email subject'),
+        body: z.string().describe('Email body content'),
+      }),
+      execute: async ({ to, subject, body }) => {
+        const response = await fetch('https://api.sendgrid.com/v3/mail/send', {
+          method: 'POST',
+          headers: {
+            'Authorization': `Bearer ${process.env.SENDGRID_API_KEY}`,
+            'Content-Type': 'application/json',
+          },
+          body: JSON.stringify({
+            personalizations: [{ to: [{ email: to }] }],
+            from: { email: 'noreply@example.com' },
+            subject,
+            content: [{ type: 'text/plain', value: body }],
+          }),
+        });
+
+        return {
+          sent: response.ok,
+          messageId: response.headers.get('X-Message-Id'),
+        };
+      },
+    }),
+  },
+});
+
+await agent.execute("Fill out the contact form and send me a confirmation email at user@example.com");
+```
+</CodeGroup>
+
+#### Custom Tools vs MCP Integrations
+
+| Custom Tools                           | MCP Integrations                        |
+|----------------------------------------|-----------------------------------------|
+| Defined inline with your code          | Connect to external services            |
+| Direct function execution              | Standard protocol                       |
+| Better performance & optimized context | Reusable across applications            |
+| Type-safe with TypeScript              | Access to pre-built integrations        |
+| Granular control                       | Network-based communication             |
+
+<Tip>
+Use custom tools when you need specific functionality within your application. Use MCP integrations when connecting to external services or when you need standardized cross-application tools.
+</Tip>
+
+### Excluding Built-in Tools
+
+Prevent the agent from using specific built-in tools during execution. This is useful when you want to restrict the agent's capabilities or avoid certain behaviors.
+
+<Note>**Non-CUA agents only.** Requires `experimental: true`. Not available when `cua: true`.</Note>
+
+#### Basic Usage
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  experimental: true, // Required for excludeTools
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+});
+
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+
+// Exclude screenshot and extract tools
+const result = await agent.execute({
+  instruction: "Navigate through the website and click the submit button",
+  maxSteps: 15,
+  excludeTools: ["screenshot", "extract"],
+});
+```
+
+#### Available Tools by Mode
+
+The tools you can exclude depend on the agent mode:
+
+<Tabs>
+<Tab title="DOM Mode">
+
+| Tool | Description |
+|------|-------------|
+| `act` | Perform semantic actions (click, type, etc.) |
+| `fillForm` | Fill form fields using DOM selectors |
+| `ariaTree` | Get accessibility tree of the page |
+| `extract` | Extract structured data from page |
+| `goto` | Navigate to a URL |
+| `scroll` | Scroll using semantic directions (up/down/left/right) |
+| `keys` | Press keyboard keys |
+| `navback` | Navigate back in history |
+| `screenshot` | Take a screenshot |
+| `think` | Agent reasoning/planning step |
+| `wait` | Wait for time or condition |
+| `search` | Web search (requires `useSearch: true` and `BROWSERBASE_API_KEY`) |
+
+</Tab>
+
+<Tab title="Hybrid Mode">
+
+| Tool | Description |
+|------|-------------|
+| `click` | Click at specific coordinates |
+| `type` | Type text at coordinates |
+| `dragAndDrop` | Drag from one point to another |
+| `clickAndHold` | Click and hold at coordinates |
+| `fillFormVision` | Fill forms using vision/coordinates |
+| `act` | Perform semantic actions |
+| `ariaTree` | Get accessibility tree |
+| `extract` | Extract data from page |
+| `goto` | Navigate to URL |
+| `scroll` | Scroll using coordinates |
+| `keys` | Press keyboard keys |
+| `navback` | Navigate back |
+| `screenshot` | Take screenshot |
+| `think` | Agent reasoning step |
+| `wait` | Wait for time/condition |
+| `search` | Web search (requires `useSearch: true` and `BROWSERBASE_API_KEY`) |
+
+</Tab>
+</Tabs>
+
+#### Use Cases
+
+```typescript
+// Prevent the agent from taking screenshots during execution
+const result = await agent.execute({
+  instruction: "Fill out the contact form",
+  excludeTools: ["screenshot"],
+});
+
+// Prevent the agent from extracting data
+const result = await agent.execute({
+  instruction: "Click through the signup flow",
+  excludeTools: ["extract"],
+});
+
+// Disable web search capability
+const result = await agent.execute({
+  instruction: "Find information on the current page",
+  excludeTools: ["search"],
+});
+```
+
+## Web Search
+
+Enable the `search` tool by setting `useSearch: true` in `agent.execute()`. This gives the agent the ability to perform web searches using the Browserbase Search API, which is useful when the agent needs to find URLs or gather information before navigating.
+
+<Note>Requires a valid Browserbase API key. Set `BROWSERBASE_API_KEY` in your environment, or pass `apiKey` in the Stagehand constructor.</Note>
+
+```typescript
+const result = await agent.execute({
+  instruction: "Find the latest pricing for Browserbase",
+  useSearch: true,
+  maxSteps: 20,
+});
+```
+
+## Variables
+
+Use variables to pass sensitive data (like passwords, API keys, or personal information) to the agent without exposing the actual values to the LLM. The agent sees only variable names and descriptions, while the actual values are substituted at runtime.
+
+<Note>**Non-CUA agents only.** Variables are not available with Computer Use Agents.</Note>
+
+### Basic Usage
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+});
+
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com/login");
+
+const result = await agent.execute({
+  instruction: "Log into the website using my credentials",
+  maxSteps: 10,
+  variables: {
+    username: {
+      value: "john@example.com",
+      description: "The user's email address for login"
+    },
+    password: {
+      value: process.env.USER_PASSWORD,
+      description: "The user's password for login"
+    }
+  }
+});
+```
+
+Variables use the same type as `act()`. You can pass simple values or rich objects with descriptions:
+
+```typescript
+// Simple values (same format as act)
+variables: {
+  username: "john@example.com",
+  password: "secret123",
+}
+
+// Rich values with descriptions (helps the agent understand context)
+variables: {
+  username: { value: "john@example.com", description: "The login email" },
+  password: { value: "secret123", description: "The login password" },
+}
+```
+
+### How Variables Work
+
+1. **LLM receives descriptions only**: The agent sees variable names and descriptions in its system prompt, but never the actual values
+2. **Placeholder syntax**: The LLM uses `%variableName%` syntax when it needs to use a variable (e.g., "type %password% into the password field")
+3. **Runtime substitution**: Actual values are substituted just before the action executes
+4. **Secure logging**: Variable values are never logged or returned in tool outputs
+
+### Supported Tools
+
+Variables work with the following agent tools:
+
+<Tabs>
+<Tab title="DOM Mode">
+
+| Tool | Usage |
+|------|-------|
+| `act` | Use `%variableName%` in the action description |
+| `fillForm` | Use `%variableName%` in field values |
+
+</Tab>
+
+<Tab title="Hybrid Mode">
+
+| Tool | Usage |
+|------|-------|
+| `type` | Use `%variableName%` in the text to type |
+| `fillFormVision` | Use `%variableName%` in field values |
+| `act` | Use `%variableName%` in the action description |
+
+</Tab>
+</Tabs>
+
+### Cache Optimization
+
+Variables are cache-friendly by design:
+- Cache keys use only variable names, not values
+- Changing variable values (e.g., different passwords) won't invalidate cached executions
+- This enables efficient replay of the same workflow with different credentials
+
+### Best Practices
+
+<Tabs>
+<Tab title="Do this">
+```typescript
+// Use variables for sensitive data
+variables: {
+  apiKey: {
+    value: process.env.API_KEY,
+    description: "API key for authentication"
+  }
+}
+```
+</Tab>
+
+<Tab title="Don't do this">
+```typescript
+// Don't hardcode sensitive values in instructions
+instruction: "Log in with password 'secret123'"
+```
+</Tab>
+</Tabs>
+
+<Tip>
+Use descriptive names and descriptions for variables. The LLM relies on the description to understand when and how to use each variable.
+</Tip>
+
+## MCP Integrations
+
+Agents can be enhanced with external tools and services through MCP (Model Context Protocol) integrations. This allows your agent to access external APIs and data sources beyond just browser interactions.
+
+<CodeGroup>
+```typescript Pass URL
+const agent = stagehand.agent({
+    mode: "cua",
+    model: "openai/computer-use-preview",
+    integrations: [
+      `https://mcp.exa.ai/mcp?exaApiKey=${process.env.EXA_API_KEY}`,
+    ],
+    systemPrompt: `You have access to web search through Exa. Use it to find current information before browsing.`
+});
+
+await agent.execute("Search for the best headphones of 2025 and go through checkout for the top recommendation");
+```
+
+```typescript Create Connection
+import { connectToMCPServer } from "@browserbasehq/stagehand";
+
+const supabaseClient = await connectToMCPServer(
+  `https://server.smithery.ai/@supabase-community/supabase-mcp/mcp?api_key=${process.env.SMITHERY_API_KEY}`
+);
+
+const agent = stagehand.agent({
+    mode: "cua",
+    model: "openai/computer-use-preview",
+    integrations: [supabaseClient],
+    systemPrompt: `You can interact with Supabase databases. Use these tools to store and retrieve data.`
+});
+
+await agent.execute("Search for restaurants and save the first result to the database");
+```
+</CodeGroup>
+
+<Tip>
+MCP integrations enable agents to be more powerful by combining browser automation with external APIs, databases, and services. The agent can intelligently decide when to use browser actions versus external tools.
+</Tip>
+
+## Streaming
+
+Enable streaming mode to receive incremental responses from the agent. This is useful for building real-time UIs that show the agent's reasoning as it progresses.
+
+<Warning>
+**Non-CUA agents only.** Streaming, callbacks, abort signals, and message continuation are only available when using the standard agent (without `mode: "cua"`). These features are not supported with Computer Use Agents.
+</Warning>
+
+<Note>These are experimental features. Set `experimental: true` in your Stagehand constructor to enable them.</Note>
+
+### Enabling Streaming Mode
+
+Set `stream: true` in the agent configuration to enable streaming:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  experimental: true, // Required for streaming
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+  stream: true, // Enable streaming mode
+});
+
+const streamResult = await agent.execute({
+  instruction: "Search for headphones on Amazon",
+  maxSteps: 20,
+});
+
+// Stream the text output incrementally
+for await (const delta of streamResult.textStream) {
+  process.stdout.write(delta);
+}
+
+// Get the final result after streaming completes
+const finalResult = await streamResult.result;
+console.log("Completed:", finalResult.completed);
+```
+
+### Stream Properties
+
+When streaming is enabled, `execute()` returns an `AgentStreamResult` with:
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `textStream` | `AsyncIterable<string>` | Incremental text output from the agent |
+| `fullStream` | `AsyncIterable<StreamPart>` | All stream events including tool calls and messages |
+| `result` | `Promise<AgentResult>` | Final result after streaming completes |
+
+```typescript
+// Stream everything (tool calls, messages, etc.)
+for await (const event of streamResult.fullStream) {
+  console.log(event);
+}
+```
+
+## Callbacks
+
+Callbacks let you hook into the agent's execution lifecycle to monitor progress, log events, or modify behavior.
+
+<Note>**Non-CUA agents only.** Callbacks require `experimental: true` and are not available with Computer Use Agents.</Note>
+
+### Available Callbacks
+
+<Tabs>
+<Tab title="Non-Streaming">
+
+When `stream: false` (default), these callbacks are available:
+
+| Callback | Description |
+|----------|-------------|
+| `prepareStep` | Called before each LLM step to modify settings |
+| `onStepFinish` | Called when each step completes |
+
+```typescript
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+});
+
+await agent.execute({
+  instruction: "Fill out the contact form",
+  maxSteps: 10,
+  callbacks: {
+    prepareStep: async (stepContext) => {
+      console.log(`Starting step ${stepContext.stepNumber}`);
+      return stepContext; // Return modified or original context
+    },
+    onStepFinish: async (event) => {
+      console.log(`Step finished: ${event.finishReason}`);
+      if (event.toolCalls) {
+        for (const tc of event.toolCalls) {
+          console.log(`Tool called: ${tc.toolName}`);
+        }
+      }
+    },
+  },
+});
+```
+
+</Tab>
+
+<Tab title="Streaming">
+
+When `stream: true`, additional callbacks are available:
+
+| Callback | Description |
+|----------|-------------|
+| `prepareStep` | Called before each LLM step to modify settings |
+| `onStepFinish` | Called when each step completes |
+| `onChunk` | Called for each stream chunk |
+| `onFinish` | Called when streaming completes |
+| `onError` | Called when an error occurs |
+| `onAbort` | Called when the stream is aborted |
+
+```typescript
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+  stream: true,
+});
+
+const streamResult = await agent.execute({
+  instruction: "Search for products",
+  maxSteps: 15,
+  callbacks: {
+    onChunk: async (chunk) => {
+      // Called for each incremental chunk
+      console.log("Chunk received:", chunk);
+    },
+    onStepFinish: async (event) => {
+      console.log(`Step completed: ${event.finishReason}`);
+    },
+    onFinish: (event) => {
+      console.log("Stream finished!");
+      console.log("Total steps:", event.steps.length);
+    },
+    onError: ({ error }) => {
+      console.error("Stream error:", error);
+    },
+    onAbort: (event) => {
+      console.log("Stream aborted after", event.steps.length, "steps");
+    },
+  },
+});
+
+// Don't forget to consume the stream
+for await (const delta of streamResult.textStream) {
+  process.stdout.write(delta);
+}
+
+await streamResult.result;
+```
+
+</Tab>
+</Tabs>
+
+<Warning>
+Streaming-only callbacks (`onChunk`, `onFinish`, `onError`, `onAbort`) will throw an error if used without `stream: true`. If you need these callbacks, enable streaming in your agent configuration.
+</Warning>
+
+## Abort Signal
+
+Cancel agent execution at any time using an `AbortSignal`. This is useful for implementing timeouts or allowing users to stop long-running tasks.
+
+<Note>**Non-CUA agents only.** Abort signals require `experimental: true` and are not available with Computer Use Agents.</Note>
+
+### Basic Usage
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  experimental: true, // Required for abort signal
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+});
+
+const controller = new AbortController();
+
+// Set a 30 second timeout
+setTimeout(() => controller.abort(), 30000);
+
+try {
+  const result = await agent.execute({
+    instruction: "Complete a complex multi-step task",
+    maxSteps: 50,
+    signal: controller.signal,
+  });
+} catch (error) {
+  if (error.name === "AgentAbortError") {
+    console.log("Task was cancelled");
+  }
+}
+```
+
+### Abort with Streaming
+
+Abort signals also work with streaming mode:
+
+```typescript
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+  stream: true,
+});
+
+const controller = new AbortController();
+
+const streamResult = await agent.execute({
+  instruction: "Describe every element on the page",
+  maxSteps: 50,
+  signal: controller.signal,
+  callbacks: {
+    onAbort: (event) => {
+      console.log(`Aborted after ${event.steps.length} steps`);
+    },
+  },
+});
+
+// Abort after receiving 10 chunks
+let chunkCount = 0;
+for await (const delta of streamResult.textStream) {
+  process.stdout.write(delta);
+  chunkCount++;
+  if (chunkCount >= 10) {
+    controller.abort();
+    break;
+  }
+}
+
+// The result promise will reject with AgentAbortError
+try {
+  await streamResult.result;
+} catch (error) {
+  console.log("Stream was aborted:", error.message);
+}
+```
+
+### Custom Abort Reasons
+
+You can pass a reason when aborting:
+
+```typescript
+controller.abort("User cancelled the operation");
+
+// The error message will include your reason
+// Error: "User cancelled the operation"
+```
+
+## Message Continuation
+
+Continue a conversation across multiple agent executions by passing the `messages` from a previous result. This is useful for multi-turn interactions or breaking complex tasks into steps while maintaining context.
+
+<Note>**Non-CUA agents only.** Message continuation requires `experimental: true` and is not available with Computer Use Agents.</Note>
+
+### Basic Continuation
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  experimental: true, // Required for message continuation
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+});
+
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com/products");
+
+// First execution: search for products
+const firstResult = await agent.execute({
+  instruction: "Search for wireless headphones and note the top 3 results",
+  maxSteps: 10,
+});
+
+console.log("First task:", firstResult.message);
+
+// Continue with the same context: ask follow-up
+const secondResult = await agent.execute({
+  instruction: "Now filter by price under $100 and tell me which of those 3 are still available",
+  maxSteps: 10,
+  messages: firstResult.messages, // Pass previous conversation
+});
+
+console.log("Follow-up:", secondResult.message);
+
+// Continue further: take action based on conversation history
+const thirdResult = await agent.execute({
+  instruction: "Add the cheapest one to the cart",
+  maxSteps: 10,
+  messages: secondResult.messages, // Chain the conversation
+});
+
+console.log("Final action:", thirdResult.message);
+```
+
+## Structured Output
+
+Define a Zod schema to receive structured data when the agent completes its task. This is useful when you need specific information extracted from the agent's execution, such as prices, dates, or other structured data.
+
+<Note>**Non-CUA agents only.** Structured output requires `experimental: true` and is not available with Computer Use Agents.</Note>
+
+<Tip>Use `.describe()` on schema fields to help the agent understand what data to extract.</Tip>
+
+<CodeGroup>
+```typescript Basic Usage
+import { z } from "zod";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  experimental: true, // Required for structured output
+});
+await stagehand.init();
+
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+});
+
+const page = stagehand.context.pages()[0];
+await page.goto("https://www.google.com/flights");
+
+const result = await agent.execute({
+  instruction: "Find the cheapest flight from NYC to LA for next week",
+  maxSteps: 20,
+  output: z.object({
+    price: z.string().describe("The price of the flight"),
+    airline: z.string().describe("The airline name"),
+    departureTime: z.string().describe("Departure time"),
+    arrivalTime: z.string().describe("Arrival time"),
+  }),
+});
+
+// Access the structured output
+console.log(result.output);
+// { price: "$199", airline: "Delta", departureTime: "8:00 AM", arrivalTime: "11:30 AM" }
+```
+
+```typescript Complex Schema
+const result = await agent.execute({
+  instruction: "Extract all items from the shopping cart",
+  output: z.object({
+    items: z.array(z.object({
+      name: z.string().describe("Product name"),
+      quantity: z.number().describe("Quantity in cart"),
+      unitPrice: z.string().describe("Price per item"),
+      totalPrice: z.string().describe("Total price for this item"),
+    })).describe("List of items in the cart"),
+    subtotal: z.string().describe("Cart subtotal before tax"),
+    tax: z.string().optional().describe("Tax amount if shown"),
+    total: z.string().describe("Final total"),
+  }),
+});
+
+console.log(`Found ${result.output?.items.length} items in cart`);
+console.log(`Total: ${result.output?.total}`);
+```
+
+```typescript With Streaming
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5-20250929",
+  stream: true,
+});
+
+const streamResult = await agent.execute({
+  instruction: "Find the top 3 search results",
+  output: z.object({
+    results: z.array(z.object({
+      title: z.string().describe("The title of the search result"),
+      url: z.string().url().describe("The URL of the search result"),
+      snippet: z.string().describe("A brief description or snippet"),
+    })).max(3).describe("Top 3 search results"),
+  }),
+});
+
+// Stream the text output
+for await (const delta of streamResult.textStream) {
+  process.stdout.write(delta);
+}
+
+// Get the structured output from the final result
+const finalResult = await streamResult.result;
+console.log(finalResult.output?.results);
+```
+</CodeGroup>
+
+## Agent Execution Configuration
+
+<Warning>
+Stagehand uses a 1288x711 viewport by default. Other viewport sizes may reduce performance. If you need to modify the viewport, you can edit in the [Browser Configuration](/v3/configuration/browser).
+</Warning>
+
+Control the maximum number of steps the agent can take to complete the task using the `maxSteps` parameter.
+
+<CodeGroup>
+```typescript TypeScript
+// Set maxSteps to control how many actions the agent can take
+await agent.execute({
+  instruction: "Sign me up for a library card",
+  maxSteps: 15 // Agent will stop after 15 steps if task isn't complete
+});
+```
+
+For complex tasks, increase the `maxSteps` limit and check task success.
+
+```typescript
+// Complex multi-step task requiring more actions
+const result = await agent.execute({
+  instruction: "Find and apply for software engineering jobs, filtering by remote work and saving 3 applications",
+  maxSteps: 30, // Higher limit for complex workflows
+});
+
+// Check if the task completed successfully
+if (result.success === true) {
+  console.log("Task completed successfully!");
+} else {
+  console.log("Task failed or was incomplete");
+}
+```
+</CodeGroup>
+
+## Best Practices
+
+Following these best practices will improve your agent's success rate, reduce execution time, and minimize unexpected errors during task completion.
+
+### Start on the Right Page
+Navigate to your target page before executing tasks:
+
+<Tabs>
+<Tab title="Do this">
+```typescript
+await page.goto('https://github.com/browserbase/stagehand');
+await agent.execute('Get me the latest PR on the stagehand repo');
+```
+</Tab>
+
+<Tab title="Don't do this">
+```typescript
+await agent.execute('Go to GitHub and find the latest PR on browserbase/stagehand');
+```
+</Tab>
+</Tabs>
+
+
+### Be Specific
+Provide detailed instructions for better results:
+
+<Tabs>
+<Tab title="Do this">
+```typescript
+await agent.execute("Find Italian restaurants in Brooklyn that are open after 10pm and have outdoor seating");
+```
+</Tab>
+
+<Tab title="Don't do this">
+```typescript
+await agent.execute("Find a restaurant");
+```
+</Tab>
+</Tabs>
+
+## Troubleshooting
+
+<AccordionGroup>
+
+
+<Accordion title="Agent is stopping before completing the task">
+**Problem**: Agent stops before finishing the requested task
+
+**Solutions**:
+- Check if the agent is hitting the maxSteps limit (default is 20)
+- Increase maxSteps for complex tasks: `maxSteps: 30` or higher
+- Break very complex tasks into smaller sequential executions
+
+```typescript
+// Increase maxSteps for complex tasks
+await agent.execute({
+  instruction: "Complete the multi-page registration form with all required information",
+  maxSteps: 40 // Increased limit for complex task
+});
+
+// Or break into smaller tasks with success checking
+const firstResult = await agent.execute({
+  instruction: "Fill out page 1 of the registration form", 
+  maxSteps: 15
+});
+
+// Only proceed if the first task was successful
+if (firstResult.success === true) {
+  await agent.execute({
+    instruction: "Navigate to page 2 and complete remaining fields",
+    maxSteps: 15
+  });
+} else {
+  console.log("First task failed, stopping execution");
+}
+```
+</Accordion>
+
+<Accordion title="Agent is failing to click the proper elements">
+**Problem**: Agent clicks on wrong elements or fails to interact with the correct UI components
+
+**Solutions**:
+- Ensure proper viewport size: Stagehand uses `1288x711` by default (optimal for Computer Use models)
+- Avoid changing viewport dimensions as other sizes may reduce performance

+
+
+Evaluations help you understand how well your automation performs, which models work best for your use cases, and how to optimize for cost and reliability. This guide covers both monitoring your own workflows and running comprehensive evaluations.
+
+## Why Evaluations Matter
+
+- **Performance Optimization**: Identify which models and settings work best for your specific automation tasks
+- **Cost Control**: Track token usage and inference time to optimize spending
+- **Reliability**: Measure success rates and identify failure patterns
+- **Model Selection**: Compare different LLMs on real-world tasks to make informed decisions
+
+<Card
+  title="Live Model Comparisons"
+  icon="scale-balanced"
+  href="https://www.stagehand.dev/evals"
+>
+  View real-time performance comparisons across different LLMs on the [Stagehand Evals Dashboard](https://www.stagehand.dev/evals)
+</Card>
+
+## Comprehensive Evaluations
+
+Evaluations help you systematically test and improve your automation workflows. Stagehand provides both built-in evaluations and tools to create your own.
+
+### Evals CLI
+![Evals CLI](/media/evals-cli.png)
+
+<Tip>
+To run evals, you'll need to clone the [Stagehand repo](https://github.com/browserbase/stagehand) and set up the CLI.
+
+We recommend using [Braintrust](https://www.braintrust.dev/docs/) to help visualize evals results and metrics.
+</Tip>
+
+The Stagehand CLI provides a powerful interface for running evaluations. You can run specific evals, categories, or external benchmarks with customizable settings.
+
+Evals are grouped into:
+1. **Act Evals** - These are evals that test the functionality of the `act` method.
+2. **Extract Evals** - These are evals that test the functionality of the `extract` method.
+3. **Observe Evals** - These are evals that test the functionality of the `observe` method.
+4. **Combination Evals** - These are evals that test the functionality of the `act`, `extract`, and `observe` methods together.
+5. **Experimental Evals** - These are experimental custom evals that test the functionality of the stagehand primitives.
+6. **Agent Evals** - These are evals that test the functionality of `agent`.
+7. **(NEW) External Benchmarks** - Run external benchmarks like WebBench, GAIA, WebVoyager, OnlineMind2Web, and OSWorld.
+

+evals run b:onlineMind2Web
+
+# OSWorld
+evals run b:osworld -f source=Mind2Web
+```
+
+#### Configuration Files
+
+You can view the specific evals in [`evals/tasks`](https://github.com/browserbase/stagehand/tree/main/packages/evals/tasks). Each eval is grouped into eval categories based on [`evals/evals.config.json`](https://github.com/browserbase/stagehand/blob/main/evals/evals.config.json).
+
+
+#### Viewing eval results
+![Eval results](/images/evals.png)
+
+Eval results are viewable on Braintrust. You can view the results of a specific eval by going to the Braintrust URL specified in the terminal when you run `npm run evals`.
+
+By default, each eval will run five times per model. The "Exact Match" column shows the percentage of times the eval was correct. The "Error Rate" column shows the percentage of times the eval errored out.
+
+You can use the Braintrust UI to filter by model/eval and aggregate results across all evals.
+
+## Creating Custom Evaluations
+
+### Step-by-Step Guide
+
+<Steps>
+<Step title="Create Evaluation File">
+Create a new file in `evals/tasks/your-eval.ts`:
+
+```typescript
+import { EvalTask } from '../types';
+
+export const customEvalTask: EvalTask = {
+  name: 'custom_task_name',
+  description: 'Test specific automation workflow',
+  
+  // Test setup
+  setup: async ({ page }) => {
+    await page.goto('https://example.com');
+  },
+  
+  // The actual test
+  task: async ({ stagehand, page }) => {
+    // Your automation logic
+    await stagehand.act({ action: 'click the login button' });
+    const result = await stagehand.extract({ 
+      instruction: 'Get the user name',
+      schema: { username: 'string' }
+    });
+    return result;
+  },
+  
+  // Validation
+  validate: (result, expected) => {
+    return result.username === expected.username;
+  },
+  
+  // Test cases
+  testCases: [
+    {
+      input: { /* test input */ },
+      expected: { username: 'john_doe' }
+    }
+  ],
+  
+  // Evaluation criteria
+  scoring: {
+    exactMatch: true,
+    timeout: 30000,
+    retries: 2
+  }
+};
+```
+</Step>
+
+<Step title="Add to Configuration">
+Update `evals/evals.config.json`:
+
+```json
+{
+  "categories": {
+    "custom": ["custom_task_name"],
+    "existing_category": ["custom_task_name"]
+  }
+}
+```
+</Step>
+
+<Step title="Run Your Evaluation">
+```bash
+# Test your custom evaluation
+evals run custom_task_name
+
+# Run the entire custom category
+evals run custom
+
+# Run with specific settings
+evals run custom_task_name -e browserbase -t 5 -m gpt-4o
+```
+</Step>
+</Steps>

+title: Extract
+description: Extract structured data from a webpage

+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+## What is `extract()`?
+
+```typescript
+await stagehand.extract("extract the name of the repository");
+```
+
+`extract()` grabs structured data from a webpage. You can define your schema with [Zod](https://github.com/colinhacks/zod) (TypeScript) or JSON. If you don't want to define a schema, you can also call `extract` with just a [natural language prompt](#instruction-only), or call `extract` [with no parameters](#no-parameters).
+
+## Why use `extract()`?
+
+<CardGroup cols={2}>
+  <Card title="Structured" icon="brackets-curly" href="#basic-schema">
+    Turn messy webpage data into clean objects that follow a schema.
+  </Card>
+  <Card title="Resilient" icon="dumbbell" href="#extract-with-context">
+    Build resilient extractions that don't break when the website changes
+  </Card>
+</CardGroup>
+
+## Return value
+
+When you use `extract()`, Stagehand will return a `Promise<ExtractResult>` with the following structure:
+<Tabs>
+<Tab title="Basic Schema">
+
+When extracting with a schema, the return type is inferred from your Zod schema:
+
+```typescript
+const result = await stagehand.extract(
+  "extract product details",
+  z.object({
+    name: z.string(),
+    price: z.number(),
+    inStock: z.boolean()
+  })
+);
+```
+
+**Example result:**
+```typescript
+{
+  name: "Wireless Mouse",
+  price: 29.99,
+  inStock: true
+}
+```
+
+</Tab>
+<Tab title="Array">
+
+When extracting an array, you get an array of objects:
+
+```typescript
+const apartments = await stagehand.extract(
+  "extract all apartment listings",
+  z.array(
+    z.object({
+      address: z.string(),
+      price: z.string(),
+      sqft: z.number()
+    })
+  )
+);
+```
+
+**Example result:**
+```typescript
+[
+  {
+    address: "123 Main St",
+    price: "$1,200/mo",
+    sqft: 750
+  },
+  {
+    address: "456 Oak Ave",
+    price: "$1,500/mo",
+    sqft: 900
+  }
+]
+```
+
+</Tab>
+<Tab title="Primitive">
+
+When extracting a single primitive value:
+
+```typescript
+const price = await stagehand.extract(
+  "extract the price",
+  z.number()
+);
+```
+
+**Example result:**
+```typescript
+19.99
+```
+
+You can also extract strings, booleans, etc.:
+
+```typescript
+const url = await stagehand.extract(
+  "extract the contact page link",
+  z.string().url()
+);
+```
+
+</Tab>
+<Tab title="Instruction Only">
+
+When calling with just an instruction (no schema):
+
+```typescript
+const result = await stagehand.extract("extract the repository name");
+```
+
+**Example result:**
+```typescript
+{
+  extraction: "stagehand"
+}
+```
+
+</Tab>
+<Tab title="No Parameters">
+
+When calling with no parameters:
+
+```typescript
+const result = await stagehand.extract();
+```
+
+**Example result:**
+```typescript
+{
+  pageText: "Accessibility Tree:\n[0-2] RootWebArea: Page Title\n  [0-37] scrollable\n    [0-118] body\n      ..."
+}
+```
+
+This returns the accessibility tree representation of the page without LLM processing.
+
+</Tab>
+</Tabs>
+
+## Advanced Configuration
+
+You can pass additional options to configure the model, timeout, selector scope, and whether to include a screenshot:
+```typescript
+const result = await stagehand.extract("extract the repository name", {
+  model: "anthropic/claude-sonnet-4-5",
+  timeout: 30000,
+  selector: "//header" // Focus on specific area
+});
+```
+
+### Server-side Caching
+
+<Note>
+`serverCache` only works when running with `env: "BROWSERBASE"`. It has no effect in local environments.
+</Note>
+
+When running on Browserbase, Stagehand automatically caches `extract()` results server-side. Repeated calls with the same inputs return instantly without consuming LLM tokens. Caching is enabled by default and can be controlled globally on the constructor or overridden per call:
+
+```typescript
+// Disable server-side caching for the entire instance
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  serverCache: false,
+});
+
+// Or disable it for a single call
+const data = await stagehand.extract("extract the repository name", { serverCache: false });
+
+// Check whether a result was served from cache
+const result = await stagehand.extract("extract the page title");
+console.log(result.cacheStatus); // "HIT" or "MISS"
+```
+
+### Targeted Extract
+
+Pass a selector to `extract` to target a specific element on the page.
+<Tip>
+This helps reduce the context passed to the LLM, optimizing token usage/speed and improving accuracy.
+</Tip>
+```typescript
+const tableData = await stagehand.extract(
+  "Extract the values of the third row",
+  z.object({
+    values: z.array(z.string())
+  }),
+  {
+    // xPath or CSS selector
+    selector: "xpath=/html/body/div/table/" 
+  }
+);
+```
+
+You can also exclude specific nodes (including their descendant nodes) with `ignoreSelectors`.
+
+```typescript
+const article = await stagehand.extract(
+  "extract the article title and body",
+  z.object({
+    title: z.string(),
+    body: z.string()
+  }),
+  {
+    ignoreSelectors: [".ad", ".newsletter-modal", "nav.related-posts"]
+  }
+);
+```
+
+<Note>
+  `ignoreSelectors` removes all matches for each selector, along with each matched node's descendants. `selector` still scopes extraction to a single resolved subtree.
+</Note>
+
+### Visual Extract
+
+Set `screenshot: true` when the extraction needs visual information from the current viewport in addition to the page accessibility tree.
+
+```typescript
+const saleBadge = await stagehand.extract(
+  "extract the text shown in the visible sale badge",
+  z.object({
+    text: z.string()
+  }),
+  {
+    screenshot: true
+  }
+);
+```
+
+<Note>
+  `screenshot: true` captures the current viewport, not the full page. It is only supported with AI SDK clients.
+</Note>
+
+
+## Best practices
+
+
+### Extract with Context
+
+You can provide additional context to your schema to help the model extract the data more accurately.
+
+```typescript
+const apartments = await stagehand.extract(
+  "Extract ALL the apartment listings and their details, including address, price, and square feet.",
+  z.array(
+    z.object({
+      address: z.string().describe("the address of the apartment"),
+      price: z.string().describe("the price of the apartment"),
+      square_feet: z.string().describe("the square footage of the apartment"),
+    })
+  )
+);
+```
+
+### Link Extraction
+<Note>
+To extract links or URLs, define the relevant field as `z.string().url()`.
+</Note>
+
+Here is how an `extract` call might look for extracting a link or URL. This also works for image links.
+
+```typescript
+const contactLink = await stagehand.extract(
+  "extract the link to the 'contact us' page",
+  z.string().url() // note the usage of z.string().url() for URL validation
+);
+
+console.log("the link to the contact us page is: ", contactLink);
+```
+
+<Tip>
+Inside Stagehand, extracting links works by asking the LLM to select an ID. Stagehand looks up that ID in a mapping of IDs -> URLs. When logging the LLM trace, you should expect to see IDs. The actual URLs will be included in the final `ExtractResult`.
+</Tip>
+
+## Troubleshooting
+
+<AccordionGroup>
+<Accordion title="Empty or partial results">
+**Problem**: `extract()` returns empty or incomplete data
+
+**Solutions**:
+- **Check your instruction clarity**: Make sure your instruction is specific and describes exactly what data you want to extract
+- **Verify the data exists**: Use `stagehand.observe()` first to confirm the data is present on the page
+- **Wait for dynamic content**: If the page loads content dynamically, use `stagehand.act("wait for the content to load")` before extracting
+
+**Solution: Wait for content before extracting**
+```typescript
+// Wait for content before extracting
+await stagehand.act("wait for the product listings to load");
+const products = await stagehand.extract(
+  "extract all product names and prices",
+  z.array(z.object({
+    name: z.string(),
+    price: z.string()
+  }))
+);
+```
+</Accordion>
+
+<Accordion title="Schema validation errors">
+**Problem**: Getting schema validation errors or type mismatches
+
+**Solutions**:
+- **Use optional fields**: Make fields optional with `z.optional()` if the data might not always be present
+- **Use flexible types**: Consider using `z.string()` instead of `z.number()` for prices that might include currency symbols
+- **Add descriptions**: Use `.describe()` to help the model understand field requirements
+
+**Solution: More flexible schema**
+```typescript
+const schema = z.object({
+  price: z.string().describe("price including currency symbol, e.g., '$19.99'"),
+  availability: z.string().optional().describe("stock status if available"),
+  rating: z.number().optional()
+});
+```
+</Accordion>
+
+<Accordion title="Inconsistent results">
+**Problem**: Extraction results vary between runs
+
+**Solutions**:
+- **Be more specific in instructions**: Instead of "extract prices", use "extract the numerical price value for each item"
+- **Use context in schema descriptions**: Add field descriptions to guide the model
+- **Combine with observe**: Use `stagehand.observe()` to understand the page structure first
+
+**Solution: Validate with observe first**
+```typescript
+// First observe to understand the page structure
+const elements = await stagehand.observe("find all product listings");
+console.log("Found elements:", elements.map(e => e.description));
+
+// Then extract with specific targeting
+const products = await stagehand.extract(
+  "extract name and price from each product listing shown on the page",
+  z.array(z.object({
+    name: z.string().describe("the product title or name"),
+    price: z.string().describe("the price as displayed, including currency")
+  }))
+);
+```
+</Accordion>
+
+<Accordion title="Performance issues">
+**Problem**: Extraction is slow or timing out
+
+**Solutions**:
+- **Reduce scope**: Extract smaller chunks of data in multiple calls rather than everything at once
+- **Use targeted instructions**: Be specific about which part of the page to focus on
+- **Consider pagination**: For large datasets, extract one page at a time
+- **Increase timeout**: Use `timeoutMs` parameter for complex extractions
+
+**Solution: Break down large extractions**
+```typescript
+// Instead of extracting everything at once
+const allData = [];
+const pageNumbers = [1, 2, 3, 4, 5];
+
+for (const pageNum of pageNumbers) {
+  await stagehand.act(`navigate to page ${pageNum}`);
+
+  const pageData = await stagehand.extract(
+    "extract product data from the current page only",
+    z.array(z.object({
+      name: z.string(),
+      price: z.number()
+    })),
+    { timeout: 60000 } // 60 second timeout
+  );
+
+  allData.push(...pageData);
+}
+```

+## What is `observe()`?
+
+```typescript
+await stagehand.observe("find the login button");
+```
+
+`observe()` discovers actionable elements on a page and returns structured actions you can execute or validate before acting. Use it to explore pages, plan multi-step workflows, cache actions, and validate elements before acting.
+
+## Why use `observe()`?

+  </Card>
+</CardGroup>
+
+## Using `observe()`
+
+Use `observe()` to discover actionable elements on a page. Here's how to find a button:
+
+```typescript
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+const actions = await stagehand.observe("find the learn more button");
+```
+
+<Note>
+**iFrame and Shadow DOM Support** Stagehand automatically handles iFrame traversal and shadow DOM elements without requiring additional configuration.
+</Note>
+
+<Accordion title="Common use cases">
+
+| Use Case | Example instruction |
+|----------|---------------------|
+| Find buttons | `find the submit button` |
+| Locate forms | `find all input fields in the form` |
+| Discover links | `find navigation links` |
+| Identify tables | `find the pricing table` |
+| Map workflows | `find all checkout steps` |
+| Validate elements | `find the delete account button` |
+
+</Accordion>
+
+
+### Return value of `observe()`?
+When you use `observe()`, Stagehand will return a `Promise<Action[]>` with the following structure:
+``` typescript
+[
+  {
+    description: 'Learn more button',
+    method: 'click',
+    arguments: [],
+    selector: 'xpath=/html[1]/body[1]/shadow-demo[1]//div[1]/button[1]'
+  }
+]
+```
+
+<Tabs>
+<Tab title="Do this">
+Use specific, descriptive instructions.
+
+```typescript
+// Clear and specific
+await stagehand.observe("find the primary call-to-action button in the hero section");
+await stagehand.observe("find all input fields in the checkout form");
+await stagehand.observe("find the delete account button in settings");
+```
+</Tab>
+
+<Tab title="Don't do this">
+Avoid vague or data-oriented queries.
+
+```typescript
+// Too vague
+await stagehand.observe("find buttons");
+
+// Use extract() for data instead
+await stagehand.observe("what is the page title?");
+```
+</Tab>
+</Tabs>
+
+## Advanced Configuration
+
+You can pass additional options to configure the model, timeout, selector scope, ignored page regions, and placeholder variables:
+
+```typescript
+// Custom model configuration
+const actions = await stagehand.observe("find navigation links", {
+  model: "openai/gpt-4o",
+  timeout: 30000,
+  selector: "//header" // Focus on specific area
+});
+```
+
+You can also exclude specific nodes, including their descendant nodes, with `ignoreSelectors`.
+
+```typescript
+const actions = await stagehand.observe("find the main call-to-action buttons", {
+  ignoreSelectors: [
+    "//aside[contains(@class, 'promo-rail')]",
+    "//div[@id='floating-chat-launcher']",
+    "//section[@aria-label='recommended articles']"
+  ]
+});
+```
+
+<Note>
+  `ignoreSelectors` removes all matches for each selector, along with each matched node's descendants. `selector` still scopes observation to a single resolved subtree.
+</Note>
+
+### Validate Then Act with Variables
+
+For login and other safety-sensitive flows, use `observe()` to discover candidate actions, validate them, and then execute them with `act()`. When you pass `variables`, `observe()` returns `%variableName%` placeholders in the suggested action arguments instead of raw secret values.
+
+```typescript
+const actions = await stagehand.observe("find the login form fields", {
+  variables: {
+    username: { value: "user@example.com", description: "The login email" },
+    password: { value: process.env.USER_PASSWORD, description: "The login password" },
+  }
+});
+
+const emailField = actions.find((action) => action.arguments?.includes("%username%"));
+const passwordField = actions.find((action) => action.arguments?.includes("%password%"));
+
+if (emailField && passwordField) {
+  await stagehand.act(emailField, {
+    variables: { username: "user@example.com" }
+  });
+
+  await stagehand.act(passwordField, {
+    variables: { password: process.env.USER_PASSWORD }
+  });
+}
+```
+
+### Server-side Caching
+
+<Note>
+`serverCache` only works when running with `env: "BROWSERBASE"`. It has no effect in local environments.
+</Note>
+
+When running on Browserbase, Stagehand automatically caches `observe()` results server-side. Repeated calls with the same inputs return instantly without consuming LLM tokens. Caching is enabled by default and can be controlled globally on the constructor or overridden per call:
+
+```typescript
+// Disable server-side caching for the entire instance
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  serverCache: false,
+});
+
+// Or disable it for a single call
+const actions = await stagehand.observe("find the login button", { serverCache: false });
+```
+
+<Note>
+  `observe()` does not currently expose a `cacheStatus` field. To check whether an `observe()` call was served from cache, use the [Browserbase session replay dashboard](https://docs.browserbase.com/features/observability#stagehand) or inspect the session logs.
+</Note>
+
+### Using with Custom Pages
+
+You can use `observe()` with pages from other browser automation libraries like Puppeteer, Playwright, or Patchright by passing the `page` option:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import puppeteer from "puppeteer-core";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+});
+await stagehand.init();
+
+// Connect with Puppeteer
+const browser = await puppeteer.connect({
+  browserWSEndpoint: stagehand.connectURL(),
+  defaultViewport: null,
+});
+
+const pages = await browser.pages();
+const customPage = pages[0];
+
+await customPage.goto("https://www.example.com/products");
+
+// Use observe with the custom Puppeteer page
+const actions = await stagehand.observe("find all product cards", {
+  page: customPage
+});
+```
+
+This works with:
+- **Puppeteer**: Pass Puppeteer Page objects
+- **Playwright**: Pass Playwright Page objects
+- **Patchright**: Pass Patchright Page objects
+- **Stagehand Context Pages**: Access pages via `stagehand.context.pages()` (default)

+## Best practices
+
+### Plan then execute
+
+Discover all actions once, then execute without additional LLM calls. This approach is 2-3x faster than separate `act()` calls.
+
+```typescript
+const formFields = await stagehand.observe("find all form input fields");
+
+for (const field of formFields) {
+  await stagehand.act(field); // No LLM call
+}
+```

+  Complete guide to planning actions with `observe()`.
+</Card>
+
+### Scope extractions
+
+Use `observe()` to narrow extraction scope and reduce token usage by up to 10x.
+
+```typescript
+const [table] = await stagehand.observe("find the pricing table");
+
+const pricing = await stagehand.extract({
+  instruction: "extract all pricing tiers",
+  schema: PricingSchema,
+  selector: table.selector
+});
+```

+</Card>
+
+### Validate before acting
+
+Check elements exist and verify their properties before performing critical operations.
+
+```typescript
+const [deleteButton] = await stagehand.observe("find the delete account button");
+
+if (deleteButton?.method === "click") {
+  await stagehand.act(deleteButton);
+} else {

+
+### Cache observed actions
+
+Store and reuse observed actions to eliminate redundant LLM calls. Build a simple cache:
+
+```typescript
+const actionCache = new Map<string, Action[]>();
+
+async function cachedObserve(instruction: string) {
+  if (actionCache.has(instruction)) {
+    return actionCache.get(instruction)!;
+  }
+
+  const actions = await stagehand.observe(instruction);
+  actionCache.set(instruction, actions);
+  return actions;
+}

+
+## Troubleshooting
+
+<AccordionGroup>
+
+<Accordion title="No elements found">
+**Problem**: `observe()` returns empty array
+
+**Solutions**:
+- Verify the element exists on the page
+- Use more specific instructions (e.g., "find the blue submit button" instead of "find button")
+- Ensure page has fully loaded before calling `observe()`
+- Enable verbose logging in Stagehand configuration to inspect detection behavior
+
+```typescript
+// Check page state before observing
+const page = stagehand.context.pages()[0];
+await page.waitForLoadState('domcontentloaded');
+
+const actions = await stagehand.observe("find the submit button");
+
+if (actions.length === 0) {
+  console.log("No elements found, trying alternative instruction");
+  const altActions = await stagehand.observe("find the button at the bottom of the form");
+}
+```
+</Accordion>
+
+<Accordion title="Inaccurate results">
+**Problem**: Descriptions or selectors don't match actual elements
+
+**Solutions**:
+- Use more capable models—check [model evals](https://stagehand.dev/evals) for recommendations
+- Provide more context in your instruction (e.g., "find the submit button in the checkout form")
+- Enable verbose logging and `logInferenceToFile` in Stagehand configuration to inspect LLM reasoning
+
+```typescript
+// More specific instructions improve accuracy
+// Instead of:
+await stagehand.observe("find the button");
+
+// Use context:
+await stagehand.observe("find the red 'Delete' button in the user settings panel");
+```
+</Accordion>
+
+<Accordion title="Wrong method suggested">
+**Problem**: The `method` field has an unexpected value
+
+**Solutions**:
+- Validate the method before using it: `if (action.method === "click") { ... }`
+- Check [supported actions](/v3/basics/act) for valid method names
+- Override with a specific method when needed: `await stagehand.act({ ...action, method: "click" })`
+
+```typescript
+const [action] = await stagehand.observe("find the submit button");
+
+// Validate method before acting
+const validMethods = ["click", "fill", "type", "press"];
+if (action && validMethods.includes(action.method || "")) {

+title: WebMCP
+sidebarTitle: WebMCP
+description: 'List and invoke tools registered by the current web page'
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+## What is WebMCP?
+
+WebMCP lets pages expose typed, first-party tools to Stagehand. Instead of inferring every action from the DOM, agents can use Stagehand to discover available tools and invoke them with structured input.
+
+<Info>
+WebMCP is different from Stagehand agent MCP integrations. Agent MCP integrations connect your agent to external MCP servers. WebMCP tools are registered by the current web page and are invoked through the `page` object.
+</Info>
+
+## Browser Support
+
+WebMCP requires Chrome or Chromium newer than version 149, and it must be launched with `--enable-features=WebMCPTesting,DevToolsWebMCPSupport`. Stagehand launches browsers with those flags by default.
+
+## Listing Tools
+
+Use `page.listWebMCPTools()` after navigating to a page that registers WebMCP tools.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+
+const page = stagehand.context.pages()[0];
+await page.goto(
+  "https://googlechromelabs.github.io/webmcp-tools/demos/react-flightsearch/",
+  { waitUntil: "load" },
+);
+
+const tools = await page.listWebMCPTools();
+console.log(tools);
+
+await stagehand.close();
+```
+
+Each tool includes its `name`, optional `description`, optional `inputSchema`, optional `annotations`, and the `frameId` where it was registered.
+
+<Note>
+`listWebMCPTools()` returns a fresh snapshot from the browser on each call. It does not reuse tools from previous pages or previous calls.
+</Note>
+
+## Invoking Tools
+
+Use `page.invokeWebMCPTool()` with the tool name and a JSON-serializable input object. The method returns an invocation immediately; await `invocation.result` for the tool's final response.
+
+```typescript
+const tools = await page.listWebMCPTools();
+const flightSearch = tools.find((tool) => tool.name === "searchFlights");
+
+if (!flightSearch) {
+  throw new Error("searchFlights was not registered on this page");
+}
+
+const invocation = await page.invokeWebMCPTool(
+  flightSearch.name,
+  {
+    origin: "SFO",
+    destination: "JFK",
+    tripType: "round-trip",
+    outboundDate: "2026-06-10",
+    inboundDate: "2026-06-17",
+    passengers: 1,
+  },
+  { frameId: flightSearch.frameId },
+);
+
+const result = await invocation.result;
+console.log(result.status);
+console.log(result.output);
+```
+
+<Tip>
+Pass `frameId` from `listWebMCPTools()` when invoking a tool. If you omitted, Stagehand resolves the frame automatically, but only if exactly one registered tool has that name.
+</Tip>
+
+## Handling Results
+
+WebMCP invocation results have one of three statuses:
+
+```typescript
+type WebMCPToolInvocationStatus = "Completed" | "Canceled" | "Error";
+```
+
+A completed tool may include `output`. A failed tool may include `errorText` or `exception`.
+
+```typescript
+const invocation = await page.invokeWebMCPTool(
+  "calculateSum",
+  { a: 19, b: 23 },
+  { frameId: tool.frameId, timeoutMs: 5_000 },
+);
+
+const result = await invocation.result;
+
+if (result.status === "Completed") {
+  console.log(result.output);
+} else {
+  console.error(result.errorText ?? result.exception);
+}
+```
+
+To cancel a pending invocation, call `invocation.cancel()`. The invocation result still resolves when the browser sends the cancellation response.
+
+```typescript
+const invocation = await page.invokeWebMCPTool(
+  "longRunningTool",
+  {},
+  { frameId: tool.frameId },
+);
+
+await invocation.cancel();
+const result = await invocation.result;
+console.log(result.status); // "Canceled"
+```
+
+## Timeouts
+
+Both WebMCP methods accept a `timeoutMs` option:
+
+- `listWebMCPTools({ timeoutMs })` waits for the page's tool snapshot. Default: `1000`
+- `invokeWebMCPTool(name, input, { timeoutMs })` sets how long `invocation.result` waits for the tool response. Default: `30000`
+
+If the browser does not support WebMCP, Stagehand throws a `StagehandUnsupportedBrowserFeatureError` with instructions for enabling the required Chrome flags.

+
+<V3Banner />
+
+
+## When to use
+
+Use an agent fallback as a failsafe when a one step action unexpectedly becomes a multi-step flow.
+
+## How it works
+
+1. [`act()`](/v3/basics/act) is attempted for the direct action
+2. If it fails, [`agent()`](/v3/basics/agent) figures out the new path
+3. Agent completes all needed steps (open menu → click button)
+
+### Example scenario
+
+**Before**: Sign in button was in the header  
+**After**: Sign in now requires: Click account menu → Click "Sign in" option
+
+A single `act("click sign in")` can't handle this change. The agent fallback can discover and execute both steps.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+try {
+  await stagehand.act("click the 'Sign In' button");
+} catch (err) {
+  console.log("Agent fallback triggered");
+
+  const agent = stagehand.agent({
+    model: "anthropic/claude-sonnet-4-6",
+    systemPrompt: "You are a helpful assistant that can use a web browser.",
+  });
+
+  const result = await agent.execute({
+    instruction: "Find and click Sign In button",
+    maxSteps: 10,
+  });
+
+  console.log(result.success ? "Agent fallback success" : "Agent fallback failed");
+
+  if (!result.success) throw err;
+}
+```

+title: Caching Actions
+description: Cache actions automatically to reduce costs and improve performance
+---
+
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+Stagehand supports two caching strategies to reduce LLM costs and speed up your automations: **Browserbase Cache** and **Local Cache**. They serve different use cases and can be used independently or together.
+
+---
+
+## Browserbase Cache
+
+Browserbase Cache is a managed, server-side caching layer built into the Stagehand API. When you run Stagehand with `env: "BROWSERBASE"`, every `act()` call is automatically cached on Browserbase's servers. Repeated calls with the same inputs return instantly without consuming any LLM tokens. You don't need to configure anything to start benefiting.
+
+The cache key is generated from the instruction, page content, and options you pass. On a cache hit, the response is returned directly from the server with no LLM inference and no token cost. You can inspect cache behavior via the `cacheStatus` field returned by `act()`. Check out the [Browserbase blog](https://www.browserbase.com/blog/stagehand-caching) for more details on how it works under the hood.
+
+### Disabling on the Constructor
+
+Pass `serverCache: false` to disable caching for all requests made by that instance:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  serverCache: false,
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://example.com");
+
+// Cache is disabled, always hits the LLM
+await stagehand.act("click the login button");
+```
+
+### Disabling per Call
+
+Override the instance setting for a single call by passing `serverCache: false` in the options:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "BROWSERBASE" }); // caching on by default
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+
+// This call skips the cache
+await stagehand.act("click the login button", { serverCache: false });
+
+// This call uses the cache as normal
+await stagehand.act("submit the form");
+```
+
+### Inspecting Cache Status
+
+`act()` returns a `cacheStatus` field you can use to verify whether a result was served from cache:
+
+```typescript
+const actResult = await stagehand.act("click the login button");
+console.log(actResult.cacheStatus); // "HIT" or "MISS"
+```
+
+### Limitations
+
+- The page URL factors in to the cache key. If the action is being made on a page with a dynamic URL, caching may not work as expected. We do filter out certain query parameters like referral trackers and analytics, but we don't catch everything just yet.
+- If the page content or structure changes, the action won't get a cache `HIT` and the LLM will be called. The subsequent actions will attempt to hit the resulting cache entry.
+
+### Best Practices
+
+<AccordionGroup>
+
+<Accordion title="Scope by selector">
+When targeting a specific part of a page, pass a `selector` to scope the accessibility tree snapshot to that container. This reduces token costs, speeds up inference, and — crucially for caching — means that changes *outside* the container don't affect the cache key.
+
+```typescript
+async function example(stagehand: Stagehand) {
+  const page = stagehand.context.pages()[0];
+  await page.goto("https://www.google.com/search?q=browserbase");
+
+  await page.waitForLoadState("networkidle");
+
+  const result = await stagehand.observe("click the first search result", {
+    // Scope to the search results container so ads, headers,
+    // and other surrounding content don't pollute the cache key.
+    selector: "#rcnt",
+  });
+}
+```
+</Accordion>
+
+<Accordion title="Use variables for dynamic values">
+Using variables in `act()` lets you generalize a single cache entry across many different values. The cache key is built from the variable *keys*, not the values — so `{ email: "alice@example.com" }` and `{ email: "bob@example.com" }` share the same entry.
+
+Without variables you'd accumulate a separate cache miss for every unique email address you type. With variables you prime the cache once and hit it forever.
+
+```typescript
+async function example(stagehand: Stagehand) {
+  const page = stagehand.context.pages()[0];
+  await page.goto("https://example.com/login");
+
+  await page.waitForLoadState("networkidle");
+
+  // First run with alice@example.com → MISS (primes cache)
+  // Any future run, regardless of email value → HIT
+  await stagehand.act(
+    "type %email% into the Email address field",
+    { variables: { email: "alice@example.com" } },
+  );
+}
+```
+</Accordion>
+
+<Accordion title="Stabilize the environment">
+Small differences in runtime state produce different accessibility trees and therefore different cache keys. Keep your environment as deterministic as possible:
+
+- **Fixed viewport size** — `await page.setViewportSize({ width: 1280, height: 720 })`
+- **Consistent user agent and locale** — set these in your browser launch options if your stack supports it
+- **Block noisy third-party requests** — analytics, A/B testing scripts, and ad trackers can inject DOM nodes that shift the cache key on every load
+
+```typescript
+const page = stagehand.context.pages()[0];
+
+// Lock the viewport so the layout is identical across runs
+await page.setViewportSize({ width: 1280, height: 720 });
+
+// Block third-party noise that pollutes the accessibility tree
+await page.route("**/*.{png,jpg,gif,svg,woff,woff2}", (route) => route.abort());
+```
+</Accordion>
+
+<Accordion title="Keep prompts deterministic">
+The instruction string is part of the cache key. Even minor wording changes — synonyms, extra adjectives, punctuation — produce a new key and a cache miss.
+
+- Anchor instructions to visible UI labels: `"click the Sign in button"` not `"click the button to log me in"`
+- Keep instructions short and free of filler words
+- Avoid instructions that contain runtime-variable text inline — use `variables` instead
+
+```typescript
+// Good: anchored to the visible label, no variance
+await stagehand.act("click the Sign in button");
+
+// Bad: inline dynamic value creates a new cache key every time
+await stagehand.act(`type ${email} into the Email address field`);
+```
+</Accordion>
+
+</AccordionGroup>
+
+---
+
+## Local Cache
+
+Local Cache writes action results to your filesystem so they persist across script runs. It works in both `LOCAL` and `BROWSERBASE` environments. When you specify a `cacheDir`, Stagehand saves every action and agent step to a local file on first run, then replays those cached actions on subsequent runs with no LLM calls, no token cost, and no network round-trip to Browserbase.
+
+This is especially useful for:
+
+- **CI/CD pipelines** - commit your cache directory to version control for consistent, deterministic runs across environments
+- **Local development** - iterate on automations without burning tokens on repeated runs
+- **Cross-machine sharing** - cache files are portable and can be shared across machines
+
+### Caching with `act()`
+
+Cache actions from `act()` by specifying a cache directory in your Stagehand constructor.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "act-cache", // Specify a cache directory
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://browserbase.github.io/stagehand-eval-sites/sites/iframe-same-proc-scroll/");
+
+// First run: uses LLM inference and caches
+// Subsequent runs: reuses cached action
+await stagehand.act("scroll to the bottom of the iframe");
+
+// Variables work with caching too
+await stagehand.act("fill the username field with %username%", {
+  variables: {
+    username: "fakeUsername",
+  },
+});
+```
+
+### Caching with `agent()`
+
+Cache agent actions (including Computer Use Agent actions) the same way. Just specify a `cacheDir`. The cache key is automatically generated based on the instruction, start URL, agent execution options, and agent configuration. Subsequent runs with the same parameters will reuse cached actions.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "agent-cache", // Specify a cache directory
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://browserbase.github.io/stagehand-eval-sites/sites/drag-drop/");
+
+const agent = stagehand.agent({
+  mode: "cua",
+  model: "google/gemini-3-flash-preview",
+  systemPrompt: "You are a helpful assistant that can use a web browser.",
+});
+
+await page.goto("https://play2048.co/");
+
+// First run: uses LLM inference and caches
+// Subsequent runs: reuses cached actions
+const result = await agent.execute({
+  instruction: "play a game of 2048",
+  maxSteps: 20,
+});
+
+console.log(JSON.stringify(result, null, 2));
+```
+
+### Cache Directory Organization
+
+You can organize your caches by using different directory names for different workflows:
+
+```typescript
+// Separate caches for different parts of your automation
+const loginStagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/login-flow"
+});
+
+const checkoutStagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/checkout-flow"
+});
+
+const dataExtractionStagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/data-extraction"
+});
+```
+
+### Best Practices
+
+<AccordionGroup>
+
+<Accordion title="Use descriptive cache directories">
+Organize caches by workflow or feature for easier management:
+
+```typescript
+// Good: descriptive cache names
+cacheDir: "cache/login-actions"
+cacheDir: "cache/search-actions"
+cacheDir: "cache/form-submissions"
+
+// Avoid: generic cache names
+cacheDir: "cache"
+cacheDir: "my-cache"
+```
+</Accordion>
+
+<Accordion title="Clear cache when DOM changes">
+If the website structure changes significantly, clear your cache directory to force fresh inference:
+
+```bash
+rm -rf cache/login-actions
+```
+
+Or programmatically:
+
+```typescript
+import { rmSync } from 'fs';
+
+// Clear cache before running if needed
+if (shouldClearCache) {
+  rmSync('cache/login-actions', { recursive: true, force: true });
+}
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/login-actions"
+});
+```
+</Accordion>
+
+<Accordion title="Commit cache for CI/CD">
+Consider committing your cache directory to version control for consistent behavior across environments:
+
+```gitignore
+# .gitignore
+# Don't ignore cache directories
+!cache/
+```
+
+This ensures your CI/CD pipelines use the same cached actions without needing to run inference on first execution.

+You might've heard of [Gemini Computer Use](https://blog.google/technology/google-deepmind/gemini-computer-use-model/), [Claude Computer Use](https://www.anthropic.com/news/3-5-models-and-computer-use), or [OpenAI's Computer Using Agent](https://openai.com/index/computer-using-agent/).
+
+These are powerful tools that can convert natural language into actions on the computer. However, you'd otherwise need to write your own code to convert these actions into Playwright commands.
+
+Stagehand not only handles the execution of Computer Use outputs, but also lets you hot-swap between Google, OpenAI, Anthropic, and Microsoft models with one line of code. You can find more information on the performance of different computer use models by visiting our [evals page](https://www.stagehand.dev/agent-evals).
+
+## How to use a Computer Use Agent in Stagehand
+
+Stagehand lets you use Computer Use Agents with one line of code:
+
+<Warning>
+**Deprecation Notice:** The `cua: true` option is deprecated and will be removed in a future version. Use `mode: "cua"` instead.
+</Warning>
+
+<Note>
+**IMPORTANT! Configure your browser dimensions**
+
+Computer Use Agents will often return XY-coordinates to click on the screen, so you'll need to configure your browser dimensions.
+
+If not specified, the default browser dimensions are 1288 x 711. You can also configure the browser dimensions in the `browserbaseSessionCreateParams` or `localBrowserLaunchOptions` options.
+</Note>
+
+
+### Configuring browser dimensions
+
+Browser configuration differs by environment:
+
+<Tabs>
+<Tab title="BROWSERBASE">
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+	env: "BROWSERBASE",

+  
+    browserbaseSessionCreateParams: {
+      browserSettings: {
+		blockAds: true,
+        viewport: {
+          width: 1288,
+          height: 711,
+        },
+      },
+  	},
+});
+
+await stagehand.init();
+```
+</Tab>
+<Tab title="LOCAL">
+```typescript

+```
+</Tab>
+</Tabs>
+
+### Direct your Computer Use Agent
+
+Call `execute` on the agent to assign a task to the agent.
+
+<CodeGroup>
+```typescript Google
+await page.goto("https://www.google.com/");
+const agent = stagehand.agent({
+    mode: "cua",
+    model: {

+    maxSteps: 20,
+    highlightCursor: true
+})
+```
+</CodeGroup>
+
+You can define the maximum number of steps the agent can take with `maxSteps`:
+
+```typescript
+await agent.execute({
+	instructions: "Apply for a library card at the San Francisco Public Library",
+	maxSteps: 10,
+});
+```

+
+
+Cost optimization in Stagehand involves balancing LLM inference costs and browser infrastructure costs. This guide provides practical strategies to reduce your automation expenses.
+
+## Quick Wins
+
+Start with these simple optimizations that can reduce costs:
+
+### 1. Use the Right Model for the Job
+
+We don't recommend using larger, more premium models for simple tasks. See our [evaluation results](https://stagehand.dev/evals) for model performance and cost comparisons across different task types.
+
+<CardGroup cols={2}>
+<Card title="Model Selection Guide" icon="brain" href="/configuration/models">
+  Choose the right LLM for your budget and accuracy requirements
+</Card>
+<Card title="Evaluation Results" icon="chart-line" href="https://www.stagehand.dev/evals">
+  See how different models perform on different tasks
+</Card>
+</CardGroup>
+
+### 2. Implement Caching
+
+Enable automatic action caching to eliminate redundant LLM calls. Simply specify a `cacheDir` when initializing Stagehand:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "action-cache", // Enable automatic caching
+});
+
+await stagehand.init();
+
+// First run: uses LLM inference and caches
+// Subsequent runs: reuses cached action (no LLM cost)
+await stagehand.act("Click the sign in button");
+```
+
+<CardGroup cols={1}>
+<Card title="Caching Guide" icon="database" href="/best-practices/caching">
+  Learn how to organize caches and manage cache directories
+</Card>
+</CardGroup>
+
+### 3. Optimize Browser Sessions
+
+Reuse sessions when possible and set appropriate timeouts. See [Browser Configuration](/configuration/browser) for details:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  browserbaseSessionCreateParams: {
+    timeout: 1800, // 30 minutes instead of default 1 hour
+    keepAlive: true, // Keep session alive between tasks
+  }
+});
+```

+<Card title="Browserbase Cost Optimization" icon="window-maximize" href="https://docs.browserbase.com/guides/cost-optimization">
+  Optimize Browserbase infrastructure costs and session management
+</Card>
+</CardGroup>
+
+## Advanced Strategies
+
+### Intelligent Model Switching
+
+Automatically fall back to cheaper models for simple tasks:
+
+```typescript
+// Use models from least to most expensive based on task complexity
+// See stagehand.dev/evals for performance comparisons
+async function smartAct(prompt: string) {
+  const models = ["google/gemini-2.5-flash", "openai/gpt-4o"];
+
+  for (const model of models) {
+    try {
+      const stagehand = new Stagehand({
+        env: "LOCAL",
+        model: model
+      });
+      await stagehand.init();
+      const [action] = await stagehand.observe(prompt);
+      await stagehand.act(action);
+      await stagehand.close();
+      return;
+    } catch (error) {
+      console.log(`Falling back to ${model}...`);
+      await stagehand.close();
+    }
+  }
+}
+```
+
+### Session Pooling
+
+Reuse browser sessions across multiple tasks:
+
+```typescript
+class SessionManager {
+  private sessions = new Map<string, Stagehand>();
+  
+  async getSession(taskType: string): Promise<Stagehand> {
+    if (this.sessions.has(taskType)) {
+      return this.sessions.get(taskType)!;
+    }
+    
+    const stagehand = new Stagehand({ env: "BROWSERBASE" });
+    await stagehand.init();
+    this.sessions.set(taskType, stagehand);
+    return stagehand;
+  }
+}
+```
+
+## Cost Monitoring
+
+Track your spending to identify optimization opportunities. See our [Observability Guide](/configuration/observability) for detailed metrics:
+
+```typescript
+// Monitor token usage
+const metrics = await stagehand.metrics;
+console.log(`Total tokens: ${metrics.totalPromptTokens + metrics.totalCompletionTokens}`);
+console.log(`Estimated cost: $${(metrics.totalPromptTokens + metrics.totalCompletionTokens) * 0.00001}`);
+```
+
+<CardGroup cols={1}>
+<Card title="Observability & Metrics" icon="chart-line" href="/configuration/observability">
+  Monitor usage patterns and track costs in real-time
+</Card>
+</CardGroup>
+
+## Budget Controls
+
+Set spending limits to prevent unexpected costs:
+
+```typescript
+class BudgetGuard {
+  private dailySpend = 0;
+  private maxDailyBudget: number;
+  
+  constructor(maxDailyBudget: number = 25) {
+    this.maxDailyBudget = maxDailyBudget;
+  }
+  
+  checkBudget(estimatedCost: number): void {
+    if (this.dailySpend + estimatedCost > this.maxDailyBudget) {
+      throw new Error(`Daily budget exceeded: $${this.maxDailyBudget}`);
+    }
+    this.dailySpend += estimatedCost;
+  }
+}
+```

+<Tip>
+**🌟 Preview: Browser Functions** - Deploy your web automation code directly on Browserbase with browser functions. Scale your `act()` automations in the cloud with zero infrastructure setup. Reach out to hello@browserbase.com to get beta access.
+</Tip>
+
+## Deploy on Vercel
+
+Securely run Stagehand on Browserbase inside a Vercel Function. This guide shows a minimal, production-safe HTTP endpoint you can call directly or on a schedule.
+
+### 1. Install Vercel CLI
+
+To download and install Vercel CLI, run one of the following commands:
+
+<CodeGroup>
+```bash pnpm
+pnpm i -g vercel
+```
+```bash yarn
+yarn global add vercel
+```
+```bash npm
+npm i -g vercel
+```
+```bash bun
+bun add -g vercel
+```
+</CodeGroup>
+
+### 2. Project layout
+
+```text
+your-project/
+  api/
+    run.ts
+  package.json
+  tsconfig.json
+  vercel.json
+```
+
+Create the structure with:
+
+```bash
+mkdir -p api
+touch api/run.ts package.json vercel.json tsconfig.json
+```
+
+### 3. `api/run.ts` (Node.js runtime)
+
+```typescript
+// api/run.ts
+import type { VercelRequest, VercelResponse } from "@vercel/node";
+import { Stagehand } from "@browserbasehq/stagehand";
+import { z } from "zod";
+
+export default async function handler(req: VercelRequest, res: VercelResponse): Promise<void> {
+  try {
+    const stagehand = new Stagehand({
+      env: "BROWSERBASE",
+      apiKey: process.env.BROWSERBASE_API_KEY!,
+      disablePino: true,
+      model: "google/gemini-2.5-flash",
+      // optional session params
+      browserbaseSessionCreateParams: {
+        region: "us-west-2",
+        browserSettings: {
+          blockAds: true,
+        },
+      },
+    });
+
+    await stagehand.init();
+    const page = stagehand.context.pages()[0];
+

+
+1. Generate a 32-character secret (you can use `openssl rand -hex 16`)
+2. Go to your project in Vercel
+3. Navigate to Settings → Deployment Protection
+4. Add the secret to "Protection Bypass for Automation"
+
+Then invoke the function with the bypass header:
+
+```bash
+curl -X POST \
+  -H "x-vercel-protection-bypass: <your-32-character-secret>" \
+  https://<your-deployment>/api/run
+```
+
+### Optional: Cron on Vercel
+
+Hit the same endpoint on a schedule by extending `vercel.json`:
+
+```json
+{
+  "$schema": "https://openapi.vercel.sh/vercel.json",
+  "functions": {
+    "api/run.ts": {
+      "maxDuration": 60
+    }
+  }
+  },
+  "crons": [
+    { "path": "/api/run", "schedule": "0 * * * *" }
+  ]
+}
+```
+
+### Features
+- **No local browsers needed** with `env: "BROWSERBASE"`. [Browserbase](https://www.browserbase.com/) provides the browsers.
+- **Fast functionality**: Offload browser work to Browserbase and return JSON promptly.
+- **Long-running tasks**: Raise `maxDuration` and/or consider Edge runtime limits depending on plan.

+description: Use auto-caching to convert agent workflows into fast, deterministic scripts
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+Agent workflows are powerful for exploring and automating complex tasks, but they can be slow and non-deterministic. This guide shows you how to use Stagehand's built-in auto-caching to convert agent-discovered workflows into fast, deterministic scripts that run 10-100x faster.
+
+## Why Use Auto-Caching with Agent?
+
+<CardGroup cols={2}>
+  <Card title="Speed" icon="bolt">
+    Cached agent workflows run 10-100x faster by skipping LLM inference on subsequent runs
+  </Card>
+  <Card title="Cost" icon="dollar-sign">
+    Eliminate repeated LLM calls—first run uses inference, subsequent runs use cache
+  </Card>
+  <Card title="Reliability" icon="shield-check">
+    Cached actions are deterministic and more predictable than fresh agent exploration
+  </Card>
+  <Card title="Simplicity" icon="wand-magic-sparkles">
+    Works automatically—just specify `cacheDir` and Stagehand handles everything
+  </Card>
+</CardGroup>
+
+## How Auto-Caching Works
+
+When you specify a `cacheDir`:
+
+1. **First run**: Agent explores and executes workflow using LLM inference
+2. **Actions cached**: All actions are automatically saved to local cache
+3. **Subsequent runs**: Same workflow reuses cached actions (no LLM calls)
+4. **Performance**: 10-100x faster execution, zero LLM tokens
+
+The cache key is automatically generated based on:
+- Agent instruction
+- Start URL
+- Agent execution options
+- Agent configuration
+
+## Basic Auto-Caching with Agent
+
+Simply add `cacheDir` when initializing Stagehand:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+// Enable auto-caching
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "agent-cache" // Automatic caching enabled
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://example.com");
+
+const agent = stagehand.agent({
+  mode: "cua",
+  model: "google/gemini-3-flash-preview",
+  systemPrompt: "You are a helpful assistant that can use a web browser.",
+});
+
+// First run: Uses LLM inference (~20-30 seconds, ~50,000 tokens)
+// Subsequent runs: Uses cached actions (~2-3 seconds, 0 tokens)
+const result = await agent.execute({
+  instruction: "Find the login form, fill in username 'demo' and password 'test123', then click submit",
+  maxSteps: 10
+});
+
+console.log("Completed:", result.success);
+console.log("Actions taken:", result.actions.length);
+
+await stagehand.close();
+```
+
+That's it! The second time you run this script, it will reuse the cached agent actions automatically.
+
+## Organizing Caches by Workflow
+
+Use descriptive cache directories for different workflows:
+
+```typescript
+// Login workflow
+const loginStagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/login-workflow"
+});
+
+// Checkout workflow
+const checkoutStagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/checkout-workflow"
+});
+
+// Data extraction workflow
+const extractStagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/extraction-workflow"
+});
+```
+
+## Complete Example: First vs Subsequent Runs
+
+### First Run (Exploration Mode)
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/github-search" // Enable caching
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://github.com");
+
+const agent = stagehand.agent({
+  mode: "cua",
+  model: "google/gemini-3-flash-preview",
+  systemPrompt: "You are a helpful assistant that can use a web browser.",
+});
+
+console.log("First run: Exploring with agent...");
+const startTime = Date.now();
+
+const result = await agent.execute({
+  instruction: "Search for 'stagehand' and click the first repository result",
+  maxSteps: 10
+});
+
+const duration = Date.now() - startTime;
+console.log(`First run completed in ${duration}ms`);
+console.log(`Actions: ${result.actions.length}`);
+console.log(`Status: ${result.success}`);
+
+await stagehand.close();
+
+// Output (example):
+// First run completed in 25000ms
+// Actions: 8
+// Status: true
+```
+
+### Subsequent Runs (Cached Mode)
+
+Run the **exact same script** again:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/github-search" // Same cache directory
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://github.com");
+
+const agent = stagehand.agent({
+  mode: "cua",
+  model: "google/gemini-3-flash-preview",
+  systemPrompt: "You are a helpful assistant that can use a web browser.",
+});
+
+console.log("Subsequent run: Using cached actions...");
+const startTime = Date.now();
+
+const result = await agent.execute({
+  instruction: "Search for 'stagehand' and click the first repository result",
+  maxSteps: 10
+});
+
+const duration = Date.now() - startTime;
+console.log(`Subsequent run completed in ${duration}ms`);
+console.log(`Actions: ${result.actions.length}`);
+console.log(`Status: ${result.success}`);
+
+await stagehand.close();
+
+// Output (example):
+// Subsequent run completed in 2500ms  ← 10x faster!
+// Actions: 8
+// Status: true
+```
+
+## Using History for Analysis
+
+While caching handles execution automatically, you can still use `stagehand.history` to analyze what happened:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import fs from "fs/promises";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/workflow"
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://example.com");
+
+const agent = stagehand.agent({
+  mode: "cua",
+  model: "google/gemini-3-flash-preview",
+  systemPrompt: "You are a helpful assistant that can use a web browser.",
+});
+
+await agent.execute({
+  instruction: "Complete the login process",
+  maxSteps: 10
+});
+
+// Analyze what the agent did
+const history = await stagehand.history;
+
+console.log(`\nWorkflow Analysis:`);
+console.log(`Total operations: ${history.length}`);
+
+const agentOps = history.filter(e => e.method === 'agent');
+const actOps = history.filter(e => e.method === 'act');
+const navOps = history.filter(e => e.method === 'navigate');
+
+console.log(`- Agent executions: ${agentOps.length}`);
+console.log(`- Act operations: ${actOps.length}`);
+console.log(`- Navigate operations: ${navOps.length}`);
+
+// Save for documentation
+await fs.writeFile(
+  'workflow-analysis.json',
+  JSON.stringify(history, null, 2)
+);
+
+await stagehand.close();
+```
+
+## Cache Management
+
+### Clear Cache When Site Changes
+
+If the website structure changes, clear the cache to force fresh exploration:
+
+```typescript
+import { rmSync } from 'fs';
+
+// Clear specific workflow cache
+rmSync('cache/login-workflow', { recursive: true, force: true });
+
+// Then run with fresh exploration
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/login-workflow" // Will rebuild cache
+});
+```
+
+### Programmatic Cache Control
+
+```typescript
+import { rmSync, existsSync } from 'fs';
+
+function clearCacheIfNeeded(cacheDir: string, maxAge: number = 7 * 24 * 60 * 60 * 1000) {
+  if (!existsSync(cacheDir)) {
+    return; // No cache to clear
+  }
+
+  const stats = statSync(cacheDir);
+  const age = Date.now() - stats.mtimeMs;
+
+  if (age > maxAge) {
+    console.log(`Cache older than ${maxAge}ms, clearing...`);
+    rmSync(cacheDir, { recursive: true, force: true });
+  }
+}
+
+// Clear cache if older than 7 days
+clearCacheIfNeeded('cache/workflow');
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/workflow"
+});
+```
+
+## Advanced Patterns
+ 
+### Fallback to Fresh Exploration
+
+Combine caching with fallback for resilience:
+
+```typescript
+async function executeWithFallback() {
+  const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    cacheDir: "cache/workflow",
+    selfHeal: true // Enable self-healing
+  });
+
+  await stagehand.init();
+  const page = stagehand.context.pages()[0];
+
+  await page.goto("https://example.com");
+
+  const agent = stagehand.agent({
+    model: "anthropic/claude-sonnet-4-6"
+  });
+
+  try {
+    // Try with cache
+    const result = await agent.execute({
+      instruction: "Complete the checkout process",
+      maxSteps: 15
+    });
+
+    console.log("Execution successful:", result.success);
+  } catch (error) {
+    console.error("Cached workflow failed:", error);
+
+    // Clear cache and retry with fresh exploration
+    rmSync('cache/workflow', { recursive: true, force: true });
+
+    console.log("Retrying with fresh exploration...");
+    const retryResult = await agent.execute({
+      instruction: "Complete the checkout process",
+      maxSteps: 15
+    });
+
+    console.log("Retry successful:", retryResult.success);
+  }
+
+  await stagehand.close();
+}
+```
+
+### Version Control for Caches
+
+Commit cache directories to ensure consistent behavior across environments:
+
+```gitignore
+# .gitignore
+
+# Commit cache directories for deterministic CI/CD
+!cache/
+!cache/**/*.json
+```
+
+```typescript
+// CI/CD pipeline will use pre-generated cache
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/production-workflow" // Committed to repo
+});
+```
+
+## Best Practices
+
+<AccordionGroup>
+
+<Accordion title="Use Descriptive Cache Names">
+Organize caches by workflow or feature:
+
+```typescript
+// Good: descriptive cache names
+cacheDir: "cache/user-registration"
+cacheDir: "cache/product-search"
+cacheDir: "cache/checkout-flow"
+
+// Avoid: generic names
+cacheDir: "cache"
+cacheDir: "my-cache"
+```
+</Accordion>
+
+<Accordion title="Cache Invalidation Strategy">
+Implement a strategy for refreshing caches:
+
+```typescript
+// Option 1: Time-based invalidation
+if (isCacheOlderThan('cache/workflow', 7)) {
+  clearCache('cache/workflow');
+}
+
+// Option 2: Version-based invalidation
+const CACHE_VERSION = 'v2';
+const cacheDir = `cache/workflow-${CACHE_VERSION}`;
+
+// Option 3: Manual invalidation flag
+if (process.env.CLEAR_CACHE === 'true') {
+  clearCache('cache/workflow');
+}
+```
+</Accordion>
+
+<Accordion title="Test in Staging First">
+Always test cached workflows in staging before production:
+
+```typescript
+const env = process.env.NODE_ENV === 'production' ? 'production' : 'staging';
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: `cache/${env}-workflow`
+});
+```
+</Accordion>
+
+<Accordion title="Monitor Cache Hit Rates">
+Track cache usage for optimization:
+
+```typescript
+const cacheHit = existsSync('cache/workflow') &&
+                statSync('cache/workflow').mtimeMs < Date.now();
+
+if (cacheHit) {
+  console.log("Cache hit - using cached workflow");
+} else {
+  console.log("Cache miss - exploring with agent");
+}
+
+// Log metrics
+metrics.recordCacheHit(cacheHit);
+```
+</Accordion>
+
+</AccordionGroup>
+
+## Performance Comparison
+
+**Without Caching (Every Run):**
+```typescript
+const stagehand = new Stagehand({ env: "BROWSERBASE" });
+// No cacheDir specified
+
+const result = await agent.execute({
+  instruction: "Complete workflow",
+  maxSteps: 10
+});
+
+// Every run: ~20-30 seconds, ~50,000 tokens
+```
+
+**With Auto-Caching (First Run):**
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/workflow"
+});
+
+const result = await agent.execute({
+  instruction: "Complete workflow",
+  maxSteps: 10
+});
+
+// First run: ~20-30 seconds, ~50,000 tokens (cached for next time)
+```
+
+**With Auto-Caching (Subsequent Runs):**
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/workflow" // Reuses cache
+});
+
+const result = await agent.execute({
+  instruction: "Complete workflow",
+  maxSteps: 10
+});
+
+// Subsequent runs: ~2-3 seconds, 0 tokens ← 10-100x faster!
+```
+
+<Note>
+Cached agent workflows run **10-100x faster** and consume **zero LLM tokens** on subsequent runs. The first run pays the exploration cost, every run after is nearly instant.
+</Note>
+
+## Troubleshooting
+
+<AccordionGroup>
+<Accordion title="Cache not being used">
+**Problem**: Workflow still slow on subsequent runs
+
+**Solutions**:
+- Verify `cacheDir` path is correct and consistent across runs
+- Ensure instruction, URL, and agent config are identical
+- Check file permissions on cache directory
+- Look for cache hit/miss logs in verbose mode
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/workflow",
+  verbose: 2 // Enable debug logs
+});
+```
+</Accordion>
+
+<Accordion title="Cached workflow fails">
+**Problem**: Cached actions fail on subsequent runs
+
+**Solutions**:
+- Website may have changed—clear cache to re-explore
+- Enable self-healing to adapt to minor changes
+- Implement fallback logic to retry with fresh exploration
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  cacheDir: "cache/workflow",
+  selfHeal: true // Adapt to changes
+});
+```
+</Accordion>
+
+<Accordion title="Too many cache directories">
+**Problem**: Cache directories growing uncontrolled
+
+**Solutions**:
+- Use version prefixes for cache directories
+- Implement automatic cleanup of old caches
+- Share cache directories for similar workflows
+
+```typescript
+// Versioned caches
+const CACHE_VERSION = '2024-01';
+const cacheDir = `cache/workflow-${CACHE_VERSION}`;
+
+// Cleanup old versions
+rmSync('cache/workflow-2023-12', { recursive: true, force: true });
+```

+description: Track and analyze Stagehand operations with the history API
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+The history API captures every Stagehand operation for debugging, auditing, and workflow analysis.
+
+## Basic Usage
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "BROWSERBASE" });
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+await page.goto("https://example.com");
+await stagehand.act("click login button");
+
+// Get complete history
+const history = await stagehand.history;
+
+console.log(`Total operations: ${history.length}`);
+history.forEach((entry, i) => {
+  console.log(`${i + 1}. ${entry.method} at ${entry.timestamp}`);
+});
+
+await stagehand.close();
+```
+
+## History Entry Structure
+
+```typescript
+interface HistoryEntry {
+  method: "act" | "extract" | "observe" | "navigate" | "agent";
+  parameters: unknown;  // Input parameters
+  result: unknown;      // Output/result
+  timestamp: string;    // ISO 8601 timestamp
+}
+```
+
+## Common Use Cases
+
+### Debugging Failures
+
+```typescript
+try {
+  await stagehand.act("click login button");
+} catch (error) {
+  const history = await stagehand.history;
+
+  history.forEach((entry, i) => {
+    const status = entry.result && 'error' in entry.result ? "FAILED" : "SUCCESS";
+    console.log(`${i + 1}. ${status} - ${entry.method}`);
+  });
+}
+```
+
+### Analyzing Timing
+
+```typescript
+const history = await stagehand.history;
+
+const timings = history.map((entry, i) => {
+  if (i === 0) return null;
+  const duration = new Date(entry.timestamp).getTime() -
+                   new Date(history[i - 1].timestamp).getTime();
+  return { operation: entry.method, duration };
+}).filter(Boolean);
+
+console.log("Slowest operations:",
+  timings.sort((a, b) => b.duration - a.duration).slice(0, 3)
+);
+```
+
+### Operation Statistics
+
+```typescript
+const history = await stagehand.history;
+
+const stats = history.reduce((acc, entry) => {
+  acc[entry.method] = (acc[entry.method] || 0) + 1;
+  return acc;
+}, {} as Record<string, number>);
+
+console.log("Operations:", stats);
+// { act: 5, extract: 2, observe: 3, navigate: 1 }
+```
+
+### Saving History
+
+```typescript
+import fs from "fs/promises";
+
+const history = await stagehand.history;
+const metrics = await stagehand.metrics;
+
+await fs.writeFile(
+  `workflow-report.json`,
+  JSON.stringify({
+    history,
+    totalOps: history.length,
+    totalTokens: metrics.totalPromptTokens + metrics.totalCompletionTokens
+  }, null, 2)
+);
+```
+
+## Filtering by Operation Type
+
+```typescript
+const history = await stagehand.history;
+
+const actions = history.filter(e => e.method === 'act');
+const extractions = history.filter(e => e.method === 'extract');
+const agentOps = history.filter(e => e.method === 'agent');
+
+console.log(`Actions: ${actions.length}`);
+console.log(`Extractions: ${extractions.length}`);
+console.log(`Agent executions: ${agentOps.length}`);
+```
+
+## Combining with Metrics
+
+```typescript
+const history = await stagehand.history;
+const metrics = await stagehand.metrics;
+
+const report = {
+  totalOps: history.length,

+
+## What's Tracked?
+
+Only Stagehand methods are tracked in history:
+
+```typescript
+// Tracked
+await stagehand.act("click button");              // ✓
+await stagehand.extract({ instruction: "..." }); // ✓
+await stagehand.observe("find elements");         // ✓
+await page.goto("https://example.com");      // ✓
+
+// Not tracked
+await page.locator("button").click();        // ✗ Native Playwright
+await page.click("button");                  // ✗ Native Playwright
+```
+
+## Best Practices
+
+- **Save history for critical workflows** - Maintain audit trails for production
+- **Inspect history when debugging** - Check the last operations to identify failures
+- **Analyze timing periodically** - Find slow operations and optimize
+- **Combine with metrics** - Get complete visibility into performance and cost

+title: "MCP Integrations"
+description: "Using Model Context Protocol (MCP) integrations to enhance agent capabilities"
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+## What are MCP Integrations?
+
+MCP (Model Context Protocol) integrations allow you to connect your Stagehand agents to external tools, APIs, and services. This enables agents to perform actions beyond browser automation, such as web search, database operations, and API calls.
+
+<Info>
+MCP integrations make your agents more powerful by combining browser automation with external capabilities. The agent can intelligently decide when to use browser actions versus external tools.
+</Info>
+
+## Connection Options
+
+There are two options for connecting to MCP servers:
+
+1. **Pass a URL directly** - The simplest approach for quick setup
+2. **Create a connection first** - Gives you more control over the connection
+
+<Note>
+MCP client support is currently only available in TypeScript.
+</Note>
+
+## Passing a URL
+
+The simplest way to add MCP integrations is by providing server URLs directly in the agent configuration:
+
+```typescript
+const agent = stagehand.agent({
+  provider: "openai",
+  model: "computer-use-preview",
+  integrations: [
+    `https://mcp.exa.ai/mcp?exaApiKey=${process.env.EXA_API_KEY}`,
+  ],
+  systemPrompt: `You have access to web search through Exa. Use it to find current information before browsing.`,
+  options: {
+    apiKey: process.env.OPENAI_API_KEY,
+  },
+});
+
+await agent.execute("Search for the best headphones of 2025 and go through checkout for the top recommendation");
+```
+
+## Creating a Connection First
+
+Alternatively, you can establish MCP connections first and then pass the client objects:
+
+```typescript
+import { connectToMCPServer } from "@browserbasehq/stagehand";
+
+// Connect to MCP server
+const supabaseClient = await connectToMCPServer(
+  `https://server.smithery.ai/@supabase-community/supabase-mcp/mcp?api_key=${process.env.SMITHERY_API_KEY}`
+);
+
+// You can also pass the config to start a local MCP server
+const notionClient = await connectToMCPServer({
+  command: "npx",
+  args: ["-y", "@notionhq/notion-mcp-server"],
+  env: {
+    NOTION_TOKEN: process.env.NOTION_TOKEN,
+  },
+});
+
+// Use the connected clients (example with Supabase + Notion)
+const agent = stagehand.agent({
+  provider: "openai", 
+  model: "computer-use-preview",
+  integrations: [supabaseClient, notionClient],
+  systemPrompt: `You can interact with Supabase databases and Notion. Use these tools to store and retrieve data.`,
+  options: {
+    apiKey: process.env.OPENAI_API_KEY,
+  },
+});
+
+await agent.execute("Search for restaurants in New Brunswick, NJ and save the first result to the database");
+```
+
+## Authenticated MCP Servers
+
+Some MCP servers require authentication via HTTP request headers. You can pass request headers through `requestOptions`:
+
+```typescript
+const authenticatedClient = await connectToMCPServer({
+  serverUrl: "https://mcp-server.example.com/mcp",
+  requestOptions: {
+    requestInit: {
+      headers: {
+        Authorization: `Bearer ${process.env.MCP_SERVER_API_KEY}`,
+      },
+    },
+  },
+});
+```
+
+
+
+## Multiple Integrations
+
+You can combine multiple MCP integrations in a single agent:
+
+```typescript
+const databaseClient = await connectToMCPServer(/* database config */);
+
+const agent = stagehand.agent({
+  integrations: [
+    `https://search-service.example.com/mcp?apiKey=${process.env.SEARCH_API_KEY}`,
+    databaseClient
+  ],
+  systemPrompt: `You have access to external tools for search and data storage. Use these tools strategically to complete tasks efficiently.`
+});
+```
+

+title: Prompting Best Practices
+description: "Write effective prompts for reliable Stagehand automation"
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+Good prompts make Stagehand reliable. Bad prompts cause failures. Here's how to write prompts that work consistently.
+
+## Act Method
+
+Use `act()` for single actions on web pages. Each action should be focused and clear.
+
+```typescript
+// Good - Single, specific actions
+await stagehand.act("click the 'Add to Cart' button");
+await stagehand.act("type 'user@example.com' into the email field");
+
+// Bad - Multiple actions combined
+await stagehand.act("fill out the form and submit it");
+await stagehand.act("login with credentials and navigate to dashboard");
+```
+
+### Use Element Types, Not Colors
+
+Describe elements by their type and function rather than visual attributes like color.
+
+```typescript
+// Good - Element types and descriptive text
+await stagehand.act("click the 'Sign In' button");
+await stagehand.act("type into the email input field");
+
+// Bad - Color-based descriptions
+await stagehand.act("click the blue button");
+await stagehand.act("type into the white input");
+```
+
+### Use Descriptive Language
+
+```typescript
+// Good - Clear element identification
+await stagehand.act("click the 'Next' button at the bottom of the form");
+await stagehand.act("type into the search bar at the top of the page");
+
+// Bad - Vague descriptions
+await stagehand.act("click next");
+await stagehand.act("type into search");
+```
+
+### Choose the Right Action Verbs
+
+- **Click** for buttons, links, checkboxes
+- **Type** for text inputs
+- **Select** for dropdowns
+- **Check/uncheck** for checkboxes
+- **Upload** for file inputs
+
+```typescript
+// Good
+await stagehand.act("click the submit button");
+await stagehand.act("select 'Option 1' from dropdown");
+
+// Bad
+await stagehand.act("click submit");
+await stagehand.act("choose option 1");
+```
+
+### Protect Sensitive Data
+
+Variables keep sensitive information out of prompts and logs.
+
+```typescript
+// Use variables for sensitive data
+await stagehand.act("type %username% into the email field", {
+  variables: { username: "user@example.com" }
+});
+
+await stagehand.act("type %password% into the password field", {
+  variables: { password: process.env.USER_PASSWORD }
+});
+```
+
+<Warning>
+Set `verbose: 0` in your Stagehand config to prevent secrets from appearing in logs.
+</Warning>
+
+## Extract Method
+
+Use `extract()` to pull structured data from pages. Define clear schemas and provide context.
+
+### Schema Best Practices
+
+Use descriptive field names, correct types, and detailed descriptions. Field descriptions provide context that helps the model understand exactly what to extract.
+
+```typescript
+// Good - Descriptive names, correct types, and helpful descriptions
+const productData = await stagehand.extract(
+  "Extract product information",
+  z.object({
+    productTitle: z.string().describe("The main product name displayed on the page"),
+    priceInDollars: z.number().describe("Current selling price as a number, without currency symbol"),
+    isInStock: z.boolean().describe("Whether the product is available for purchase")
+  })
+);
+
+// Bad - Generic names, wrong types, no descriptions
+const data = await stagehand.extract(
+  "Get product details",
+  z.object({
+    name: z.string(), // Too generic, no context
+    price: z.string(), // Should be number
+    stock: z.string() // Should be boolean, no context
+  })
+);
+```
+
+### Use Proper URL Types
+
+Specify URL types with `z.string().url()` to tell Stagehand to extract URLs.
+
+```typescript
+// Good - Tells Stagehand to extract URLs
+const links = await stagehand.extract(
+  "Extract navigation links",
+  z.array(z.object({
+    text: z.string(),
+    url: z.string().url() // Required for URL extraction
+  }))
+);
+
+// Single URL extraction
+const contactUrl = await stagehand.extract(
+  "extract the contact page URL",
+  z.string().url()
+);
+```
+
+## Observe Method
+
+Use `observe()` to discover actionable elements before acting on them.
+
+### Check Elements First
+
+Verify elements exist before taking action to avoid errors.
+
+```typescript
+// Check for elements first
+const loginButtons = await stagehand.observe("Find the login button");
+
+if (loginButtons.length > 0) {
+  await stagehand.act(loginButtons[0]);
+} else {
+  console.log("No login button found");
+}
+```
+
+### Be Specific About Element Types
+
+```typescript
+// Good - Specific element types
+const submitButtons = await stagehand.observe("Find submit button in the form");
+const dropdowns = await stagehand.observe("Find the state dropdown menu");
+
+// Bad - Too vague
+const elements = await stagehand.observe("Find submit stuff");
+const things = await stagehand.observe("Find state selection");
+```
+
+## Agent Method
+
+Use `agent()` for complex, multi-step workflows. Provide detailed instructions and set appropriate limits.
+
+### Navigate First
+
+Don't include navigation in agent tasks. Handle it separately.
+
+```typescript
+// Good - Navigate first
+await page.goto('https://amazon.com');
+await agent.execute('Search for wireless headphones under $100 and add the best rated one to cart');
+
+// Bad - Navigation in task
+await agent.execute('Go to Amazon, search for headphones, and add one to cart');
+```
+
+### Be Highly Specific
+
+Detailed instructions lead to better results.
+
+```typescript
+// Good - Detailed instructions
+await agent.execute({
+  instruction: "Find Italian restaurants in Brooklyn that are open after 10pm, have outdoor seating, and are rated 4+ stars. Save the top 3 results.",
+  maxSteps: 25
+});
+
+// Bad - Vague instructions
+await agent.execute("Find some good restaurants");
+```
+
+### Set Appropriate Step Limits
+
+Match step limits to task complexity.
+
+```typescript
+// Simple task - fewer steps
+await agent.execute({
+  instruction: "Subscribe to the newsletter with email 'user@example.com'",
+  maxSteps: 10
+});
+
+// Complex task - more steps  
+await agent.execute({
+  instruction: "Research and compare 5 project management tools with pricing and features",
+  maxSteps: 50
+});
+```
+
+### Include Success Criteria
+
+Tell the agent how to know when it's done.
+
+```typescript
+// Good - Clear success criteria
+await agent.execute({
+  instruction: "Add 3 smartphone cases to cart and confirm the cart shows exactly 3 items with total price",
+  maxSteps: 20
+});
+
+// Bad - No validation
+await agent.execute("Add some items to cart");
+```
+
+## Common Mistakes to Avoid
+
+- **Combining multiple actions** - Keep each `act()` call to one action
+- **Using vague descriptions** - Be specific about which elements to interact with  
+- **Exposing sensitive data** - Always use variables for credentials
+- **Skipping validation** - Check results before proceeding
+
+## Testing Your Prompts
+
+1. **Start simple** - Test basic functionality first
+2. **Add complexity gradually** - Build up to complex workflows
+3. **Monitor results** - Use logging to understand what's happening
+4. **Iterate based on failures** - Refine prompts when they don't work
+Remember: Good prompting is iterative. When in doubt, be more specific rather than less.

+title: Speed Optimization
+sidebarTitle: Speed Optimization
+description: Optimize Stagehand performance for faster automation and reduced latency
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+Stagehand performance depends on several factors: DOM processing speed, LLM inference time, browser operations, and network latency. This guide provides proven strategies to maximize automation speed.
+
+## Quick Performance Wins
+
+### 1. Plan Ahead with Observe
+
+
+Use a single `observe()` call to plan multiple actions, then execute them efficiently:
+
+```typescript
+// Instead of sequential operations with multiple LLM calls
+await stagehand.act("Fill name field");        // LLM call #1
+await stagehand.act("Fill email field");       // LLM call #2
+await stagehand.act("Select country dropdown"); // LLM call #3
+
+// Use single observe to plan all form fields - one LLM call
+const formFields = await stagehand.observe("Find all form fields to fill");
+
+// Execute all actions without LLM inference
+for (const field of formFields) {
+  await stagehand.act(field); // No LLM calls!
+}
+```
+
+<Note>
+**Performance Tip**: Acting on `observe` results avoids LLM inference entirely. This approach is 2-3x faster than direct `act()` calls and is the recommended pattern for multi-step workflows.
+</Note>
+
+<Card title="Caching Guide" icon="database" href="/best-practices/caching">
+  Learn advanced caching patterns and cache invalidation strategies
+</Card>
+
+### 2. Optimize DOM Processing
+
+Reduce DOM complexity before Stagehand processes the page:
+
+```typescript
+// Remove heavy elements that slow down processing
+await page.evaluate(() => {
+  // Remove video elements
+  document.querySelectorAll('video, iframe').forEach(el => el.remove());
+  
+  // Hide complex animations
+  document.querySelectorAll('[style*="animation"]').forEach(el => {
+    (el as HTMLElement).style.animation = 'none';
+  });
+});
+
+// Then perform Stagehand operations
+await stagehand.act("Click the submit button");
+```
+
+### 3. Set Appropriate Timeouts
+
+Use shorter timeouts for simple operations and longer ones for complex page loads:
+
+```typescript
+// Simple actions - reduce action timeout
+await stagehand.act("Click the login button", {
+  timeout: 5000  // Default is 30000ms, reduce for simple clicks
+});
+
+// Complex page loads - optimize navigation
+const page = stagehand.context.pages()[0];
+await page.goto("https://heavy-spa.com", {
+  waitUntil: "domcontentloaded", // Don't wait for all resources
+  timeout: 15000 // Shorter than default 30s
+});
+```
+
+## Performance Monitoring and Benchmarking
+
+Track performance metrics and measure optimization impact:
+
+### Performance Tracking
+
+```typescript
+class PerformanceTracker {
+  private speedMetrics: Map<string, number[]> = new Map();
+
+  async timedAct(page: Page, prompt: string): Promise<ActResult> {
+    const start = Date.now();
+    const result = await stagehand.act(prompt);
+    const duration = Date.now() - start;
+    
+    if (!this.speedMetrics.has(prompt)) {
+      this.speedMetrics.set(prompt, []);
+    }
+    this.speedMetrics.get(prompt)!.push(duration);
+    
+    console.log(`Action "${prompt}" took ${duration}ms`);
+    return result;
+  }
+
+  getAverageTime(prompt: string): number {
+    const times = this.speedMetrics.get(prompt) || [];
+    return times.reduce((a, b) => a + b, 0) / times.length;
+  }
+}
+```
+
+Example Output:
+```
+Action "Fill form" took 1000ms
+Action "Click submit" took 2000ms
+Action "Confirm submission" took 5000ms
+```
+
+### Before vs After Benchmarking
+
+```typescript
+// Before optimization
+console.time("workflow");
+await stagehand.act("Fill form");
+await stagehand.act("Click submit");
+await stagehand.act("Confirm submission");
+console.timeEnd("workflow"); // 8000ms
+
+// After optimization with observe planning
+console.time("workflow-optimized");
+const workflowActions = await stagehand.observe("Find form, submit, and confirm elements");
+
+// Execute actions sequentially to avoid conflicts
+for (const action of workflowActions) {
+  await stagehand.act(action);
+}
+console.timeEnd("workflow-optimized"); // 500ms
+```
+
+Example Output:
+```
+Workflow took 8000ms
+Optimized workflow took 500ms
+```

+const requiredFields = formElements.filter(e => 
+  e.description.includes('required') || e.description.includes('*')
+);
+
+console.log(`Found ${requiredFields.length} required fields to complete`);
+
+// Fill form systematically
+for (const field of requiredFields) {
+  await stagehand.act(field);
+  // Add appropriate input based on field type
+}
+```
+
+### Dynamic Content & SPA Navigation
+
+```typescript
+// Wait for and discover dynamically loaded content
+await page.waitForLoadState('networkidle');
+
+const dynamicElements = await stagehand.observe({
+  instruction: "Find newly loaded content, infinite scroll triggers, or loading indicators",
+  domSettleTimeoutMs: 15000 // Wait longer for dynamic content
+});
+
+// Handle infinite scroll
+const scrollTriggers = dynamicElements.filter(e => 
+  e.description.toLowerCase().includes('load more') ||
+  e.description.toLowerCase().includes('scroll')
+);
+
+if (scrollTriggers.length > 0) {
+  await stagehand.act(scrollTriggers[0]);
+  // Recursively observe new content
+  const newContent = await stagehand.observe("Find additional items");
+}
+```
+
+### Multi-Step Workflow Planning
+
+```typescript
+// Plan entire checkout flow upfront
+async function planCheckoutWorkflow() {
+  // Step 1: Cart page analysis
+  await page.goto('/cart');
+  const cartActions = await stagehand.observe("Find checkout and cart modification options");
+  
+  // Step 2: Checkout page analysis  
+  const checkoutButton = cartActions.find(a => a.description.includes('checkout'));
+  if (checkoutButton) await stagehand.act(checkoutButton);
+  
+  const checkoutActions = await stagehand.observe("Find payment forms and shipping options");
+  
+  // Step 3: Plan execution order
+  const shippingFields = checkoutActions.filter(a => a.description.includes('shipping'));
+  const paymentFields = checkoutActions.filter(a => a.description.includes('payment'));
+  const submitButton = checkoutActions.find(a => a.description.includes('complete order'));
+  
+  return { shippingFields, paymentFields, submitButton };
+}
+
+// Execute planned workflow
+const workflow = await planCheckoutWorkflow();
+// Fill shipping → payment → submit

+
+For local sessions, use the `userDataDir` option:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({

+
+#### Browserbase Sessions
+
+For Browserbase sessions, use [contexts](https://docs.browserbase.com/features/contexts) to persist browser data:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",

+title: 'Using Multiple Tabs'
+description: 'Act on multiple tabs with Stagehand'
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+Many modern web applications open new tabs when users click certain buttons or links. Without proper multitab support, automation scripts break when expected content appears in a new tab rather than the current one. Stagehand's multitab capabilities ensure your automations work seamlessly across multitab workflows.
+
+## The Stagehand Page
+
+Stagehand automatically adapts to multitab workflows. The active page (accessed via `context.activePage()`) always points to the most recently opened or active tab, ensuring your automations continue working even when new tabs are created.
+
+This means you can continue using familiar patterns:
+
+```typescript
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+await stagehand.act("click the button that opens a new tab");
+// page now automatically points to the new tab
+await stagehand.extract("get data from new tab");
+```
+
+<Warning>
+**Important**: [Stagehand Agent](/v3/basics/agent) will always operate on the active page. If you need an agent to work across specific tabs, you'll need to manage page switching manually.
+</Warning>
+
+## Manual Page Management
+
+For more control or multitab workflows, you can manage multiple tabs explicitly:
+
+```typescript
+// Create a second page
+await stagehand.context.newPage();
+const pages = stagehand.context.pages();
+
+const githubPage = pages[0];
+const pythonPage = pages[1];
+
+// Navigate each page to different repositories
+await githubPage.goto("https://github.com/browserbase/stagehand");
+await pythonPage.goto("https://github.com/browserbase/stagehand-python");
+
+// Extract data from both pages simultaneously
+const [stagehandStars, stagehandPythonStars] = await Promise.all([
+  stagehand.extract("extract the repository stars", { page: githubPage }),
+  stagehand.extract("extract the repository stars", { page: pythonPage })
+]);
+
+console.log(`Stagehand stars: ${stagehandStars}`);
+console.log(`Stagehand-Python stars: ${stagehandPythonStars}`);

+Stagehand supports two primary environments:
+
+- **Browserbase** - Cloud-managed browser infrastructure optimized for production web automation at scale
+- **Local** - Run browsers directly on your machine for development and debugging
+
+## Browserbase Environment
+
+Browserbase provides managed cloud browser infrastructure optimized for web automation at scale. It offers advanced features like stealth mode, proxy support, and persistent contexts.
+
+<Card icon="cloud" title="Browserbase" href="https://docs.browserbase.com" description="Explore the features and benefits of using Browserbase for scalable web automation.">
+  Discover the power of cloud-managed browser infrastructure with Browserbase.
+</Card>
+
+### Multi-Region Support
+
+Stagehand API is available in multiple regions to optimize latency and support data residency requirements. The SDK automatically routes requests to the correct regional API endpoint based on your browser session's region.
+
+| Region | API Endpoint |
+| --- | --- |
+| **us-west-2** (Default) | https://api.stagehand.browserbase.com |
+| **us-east-1** | https://api.use1.stagehand.browserbase.com |
+| **eu-central-1** | https://api.euc1.stagehand.browserbase.com |
+| **ap-southeast-1** | https://api.apse1.stagehand.browserbase.com |
+
+Configure your browser session region in `browserbaseSessionCreateParams`:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  browserbaseSessionCreateParams: {
+    region: "eu-central-1", // Browser runs in Frankfurt
+  },
+});
+
+await stagehand.init();
+```
+
+<Warning>
+The API endpoint must match your browser session region. If there's a mismatch, you'll receive an error:
+`Session is in region 'X' but this API instance serves 'Y'. Please route your request to the X Stagehand API endpoint.`
+</Warning>
+
+### Disabling Stagehand API
+
+If you want to use Stagehand purely as a local library without routing through the Stagehand API, you can disable API mode:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  disableAPI: true, // Disable Stagehand API - runs locally with Browserbase
+});
+
+await stagehand.init();
+```
+
+<Tip>
+Disabling the API is useful when you want to manage browser sessions directly while still using Stagehand's automation features locally.
+</Tip>
+
+### Environment Variables
+
+Before getting started, set up the required environment variables:
+
+<CodeGroup>
+```bash .env
+BROWSERBASE_API_KEY=your_api_key_here
+```
+</CodeGroup>
+
+<Tip>
+Get your API key from the [Browserbase Dashboard](https://browserbase.com/overview)
+</Tip>
+
+### Using Stagehand with Browserbase
+
+#### Basic Setup
+
+The simplest way to get started is with default settings:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+});
+
+await stagehand.init();
+```
+
+#### Advanced Configuration
+
+Configure browser settings, proxy support, and other session parameters:
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  // Optional: API Key will be pulled directly from your environment
+  apiKey: process.env.BROWSERBASE_API_KEY,
+  browserbaseSessionCreateParams: {
+    proxies: true,
+    region: "us-west-2",
+    browserSettings: {
+      viewport: { width: 1920, height: 1080 },
+      blockAds: true,
+    },
+  },
+});
+
+await stagehand.init();
+console.log("Session ID:", stagehand.sessionId);
+```
+
+<Accordion title="Advanced Browserbase Configuration Example">
+    ```typescript
+const stagehand = new Stagehand({
+      env: "BROWSERBASE",
+      apiKey: process.env.BROWSERBASE_API_KEY,
+      browserbaseSessionCreateParams: {
+        proxies: true,
+        region: "us-west-2",
+        timeout: 3600, // 1 hour session timeout
+        keepAlive: true, // Available on Startup plan
+        browserSettings: {
+          verified: false, // this is a Scale Plan feature - reach out to support@browserbase.com to enable
+          blockAds: true,
+          solveCaptchas: true,
+          recordSession: false,
+          viewport: {
+            width: 1920,
+            height: 1080,
+          },
+        },
+        userMetadata: {
+          userId: "automation-user-123",
+          environment: "production",
+        },
+      },
+    });
+    ```
+</Accordion>
+
+### Alternative: Browserbase SDK
+
+If you prefer to manage sessions directly, you can use the Browserbase SDK:
+
+```typescript
+import { Browserbase } from "@browserbasehq/sdk";
+
+const bb = new Browserbase({ 
+  apiKey: process.env.BROWSERBASE_API_KEY! 
+});
+
+const session = await bb.sessions.create({
+  // Add configuration options here
+});
+```
+
+#### Connecting to an Existing Session
+
+Connect to a previously created Browserbase session using its session ID:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  browserbaseSessionID: "existing-session-uuid-here",
+});
+
+await stagehand.init();
+console.log("Resumed Session ID:", stagehand.sessionId);
+```
+
+## Local Environment
+
+The local environment runs browsers directly on your machine, providing full control over browser instances and configurations. Ideal for development, debugging, and scenarios requiring custom browser setups.
+
+### Environment Comparison
+
+| Feature | Browserbase | Local |
+| --- | --- | --- |
+| **Scalability** | High (cloud-managed) | Limited (local resources) |
+| **Stealth Features** | Advanced fingerprinting | Basic stealth |
+| **Proxy Support** | Built-in residential proxies | Manual configuration |
+| **Session Persistence** | Cloud context storage | File-based user data |
+| **Geographic Distribution** | Multi-region deployment | Single machine |
+| **Debugging** | Session recordings & logs | Direct DevTools access |
+| **Setup Complexity** | Environment variables only | Browser installation required |
+| **Cost** | Usage-based pricing | Infrastructure & maintenance |
+| **Best For** | Production, scale, compliance | Development, debugging |
+
+### Basic Local Setup
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL"
+});
+  
+await stagehand.init();
+console.log("Session ID:", stagehand.sessionId);
+```
+
+### Advanced Local Configuration
+
+Customize browser launch options for local development:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  localBrowserLaunchOptions: {
+    headless: false, // Show browser window
+    devtools: true, // Open developer tools
+    viewport: { width: 1280, height: 720 },
+    executablePath: '/opt/google/chrome/chrome', // Custom Chrome path
+    port: 9222, // Fixed CDP debugging port
+    ignoreDefaultArgs: [
+      '--site-per-process',
+    ], // Remove specific default launch args
+    args: [
+      '--no-sandbox',
+      '--disable-setuid-sandbox',
+      '--disable-web-security',
+      '--allow-running-insecure-content',
+    ],
+    userDataDir: './chrome-user-data', // Persist browser data
+    preserveUserDataDir: true, // Keep data after closing
+    chromiumSandbox: false, // Disable sandbox (adds --no-sandbox)
+    ignoreHTTPSErrors: true, // Ignore certificate errors
+    locale: 'en-US', // Set browser language
+    deviceScaleFactor: 1.0, // Display scaling
+    proxy: {
+      server: 'http://proxy.example.com:8080',
+      username: 'user',
+      password: 'pass'
+    },
+    downloadsPath: './downloads', // Download directory
+    acceptDownloads: true, // Allow downloads
+    connectTimeoutMs: 30000, // Connection timeout
+  },
+});
+
+await stagehand.init();
+```
+
+#### Default Local Launch Arguments
+
+When Stagehand launches a local browser, it adds the following Chrome arguments before any values in `localBrowserLaunchOptions.args`:
+
+```typescript
+[
+  "--remote-allow-origins=*",
+  "--no-first-run",
+  "--no-default-browser-check",
+  "--disable-dev-shm-usage",
+  "--site-per-process",
+]
+```
+
+Chrome Launcher also adds its own default arguments. To remove default arguments, set `localBrowserLaunchOptions.ignoreDefaultArgs`:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  localBrowserLaunchOptions: {
+    ignoreDefaultArgs: ["--site-per-process"],
+    args: [
+      "--disable-features=site-per-process,IsolateOrigins",
+      "--renderer-process-limit=6",
+    ],
+  },
+});
+```
+
+Use `ignoreDefaultArgs: true` to remove all default arguments. Use a string array to remove only exact matches while preserving the rest.
+
+## Advanced Configuration
+
+### Keep Alive
+
+The `keepAlive` option controls whether the browser remains running after `stagehand.close()` is called or when the parent process exits unexpectedly (e.g., crash, `SIGTERM`, `SIGINT`).
+
+By default, Stagehand terminates the browser and cleans up all resources when it shuts down. Setting `keepAlive: true` keeps the browser running independently so you can reconnect to it later.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  keepAlive: true,
+});
+
+await stagehand.init();
+
+// The browser session continues running after close()
+await stagehand.close();
+
+// Later, reconnect to the same session
+const stagehand2 = new Stagehand({
+  env: "BROWSERBASE",
+  browserbaseSessionID: stagehand.browserbaseSessionID,
+});
+await stagehand2.init();
+```
+
+#### Behavior by Environment
+
+| Behavior | `keepAlive: true` | `keepAlive: false` (default) |
+| --- | --- | --- |
+| **Browserbase** | Session stays active after `close()` | Session is terminated via API |
+| **Local** | Chrome process continues running | Chrome process is killed and temp profile is removed |
+| **On crash/signal** | Browser is left running | Browser is automatically cleaned up |
+
+#### Local Environment
+
+When running locally with `keepAlive: true`, the Chrome process is detached from the Node.js event loop, allowing your script to exit while the browser stays open. This is useful for debugging or for handing off a browser session to another process.
+
+```typescript
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  keepAlive: true,
+  localBrowserLaunchOptions: {
+    headless: false,
+  },
+});
+
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+
+// Browser window stays open after the script exits
+await stagehand.close();
+```
+
+#### Browserbase Environment
+
+On Browserbase, `keepAlive: true` keeps the cloud session active so you can reconnect later using `browserbaseSessionID`. This is useful for long-running workflows that span multiple script executions.
+
+<Note>
+The top-level `keepAlive` option overrides `browserbaseSessionCreateParams.keepAlive` when both are provided.
+</Note>
+
+### Fixed CDP Debugging Port
+
+Specify a fixed Chrome DevTools Protocol (CDP) debugging port instead of using a randomly assigned one.
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  localBrowserLaunchOptions: {
+    port: 9222,
+  },
+});
+
+await stagehand.init();
+```
+
+<Tip>
+If no `port` is specified, a random port will be assigned.
+</Tip>
+
+### DOM Settle Timeout
+
+Configure how long Stagehand waits for the DOM to stabilize before taking actions.
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  domSettleTimeout: 3000 // Wait up to 3 seconds for DOM to settle
+});
+```
+
+#### What is DOM Settling?
+
+DOM settling ensures that:
+- **Animations complete** before interacting with elements
+- **Lazy-loaded content** has time to appear
+- **JavaScript updates** finish before actions are taken
+- **Dynamic content** is fully rendered
+
+#### When to Adjust
+
+Increase `domSettleTimeout` for pages with:
+- Heavy animations or transitions
+- Lazy-loading or infinite scroll
+- Dynamic JavaScript frameworks (React, Vue, Angular)
+- Complex single-page applications
+
+```typescript
+// For fast, static pages
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  domSettleTimeout: 500 // Minimal wait
+});
+
+// For dynamic, animated pages
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  domSettleTimeout: 5000 // Longer wait for stability
+});
+```
+
+<Warning>
+Setting `domSettleTimeout` too low may cause actions to fail on elements that aren't ready. Setting it too high increases execution time unnecessarily.
+</Warning>
+
+## Troubleshooting
+
+<AccordionGroup>
+<Accordion title="Browserbase Authentication Errors">

+
+
+Stagehand provides comprehensive logging capabilities to help you debug automation workflows, track execution, and diagnose issues. Configure logging levels, structured output, and debugging tools for both development and production environments.
+
+## Quick Start
+
+Choose your logging setup based on your environment:
+
+<CodeGroup>
+```typescript Development
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  verbose: 2,  // Full debug output
+  // restOfYourConfiguration...
+});
+```
+
+```typescript Production
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  verbose: 1,  // Standard logging - less noise
+  disablePino: true,  // Disable default console logging - no console spam
+  // logger: yourProductionLogger,  // Send to observability platform like Sentry or DataDog
+  // restOfYourConfiguration...
+});
+```
+
+```typescript Testing
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  verbose: 1,
+  // Pino automatically disabled in test environments - no worker thread issues
+  // logger: yourTestLogger,  // Send to test logging framework like Jest
+  // restOfYourConfiguration...
+});
+```
+</CodeGroup>
+
+---
+

+## File-Based Session Logging
+
+Enable detailed file-based logging for all Stagehand operations by setting a config directory. This creates comprehensive logs for `agent.execute`, `act`, `observe`, `extract`, CDP events, and LLM requests/responses.
+
+### Setup
+
+Add to your shell configuration (`~/.zshrc`, `~/.bashrc`, etc.):
+
+```bash
+export BROWSERBASE_CONFIG_DIR=~/.config/browserbase
+```
+
+Then reload your shell or run `source ~/.zshrc`.
+
+### Usage
+
+Run your Stagehand script as normal:
+
+```bash
+tsx run_some_script_that_imports_stagehand.ts
+```
+
+Logs are written to `~/.config/browserbase/sessions/<session-id>/` with a `latest` symlink pointing to the most recent session.
+
+### Viewing Logs
+
+<Tabs>
+<Tab title="Real-time Monitoring">
+Follow all logs as they happen:
+
+```bash
+tail -f ~/.config/browserbase/sessions/latest/*.log
+```
+
+Or watch specific log types:
+
+```bash
+# LLM requests and responses only
+tail -f ~/.config/browserbase/sessions/latest/llm_events.log
+
+# CDP (Chrome DevTools Protocol) events only
+tail -f ~/.config/browserbase/sessions/latest/cdp_events.log
+```
+</Tab>
+
+<Tab title="Chronological Review">
+View unified output sorted by timestamp:
+
+```bash
+cat ~/.config/browserbase/sessions/latest/*.log | sort
+```
+</Tab>
+
+<Tab title="Historical Sessions">
+Browse previous session logs:
+
+```bash
+ls ~/.config/browserbase/sessions/
+# Output: 2025-01-06_14-30-45_abc123  2025-01-06_15-45-12_def456  latest
+
+cat ~/.config/browserbase/sessions/2025-01-06_14-30-45_abc123/*.log | sort
+```
+</Tab>
+</Tabs>
+
+### Log Files
+
+Each session directory contains:
+
+| File | Contents |
+|------|----------|
+| `llm_events.log` | LLM requests and responses for act, extract, observe, and agent operations |
+| `cdp_events.log` | Chrome DevTools Protocol calls and events |
+| `stagehand.log` | General Stagehand operations and state changes |
+
+<Note>
+This is especially useful for debugging agent workflows where you need to trace the full sequence of LLM decisions, browser actions, and CDP interactions.

+## Reference
+
+### Logging Configuration
+
+All logging options are passed to the Stagehand constructor:
+
+```typescript
+const stagehand = new Stagehand({
+  // ... your other configurations (env, model, etc.)
+
+  // Logging options:
+  verbose?: 0 | 1 | 2;                   // Log level (default: 1)
+  logger?: (line: LogLine) => void;      // External logger function
+  disablePino?: boolean;                 // Disable Pino backend (default: false)
+  logInferenceToFile?: boolean;          // Save LLM requests to disk (default: false)
+});
+```
+
+| Option | Default | Description |
+|--------|---------|-------------|
+| `verbose` | `1` | Log level: `0` = errors only, `1` = info, `2` = debug |
+| `logger` | `undefined` | Custom logger function for external platforms |
+| `disablePino` | `false` | Disable Pino (auto `true` in tests) |
+| `logInferenceToFile` | `false` | Save LLM requests to disk (default: false) |
+
+### Log Structure
+
+Each log entry follows a structured format:
+
+```typescript
+interface LogLine {
+  message: string;              // "act completed successfully"
+  level?: 0 | 1 | 2;            // error | info | debug
+  category?: string;            // "action", "llm", "browser", "cache"
+  timestamp?: string;           // ISO 8601 timestamp
+  auxiliary?: {                 // Additional structured metadata
+    [key: string]: {
+      value: string;             // Serialized value

+  **(NEW) Model Gateway** — Use your Browserbase API key to access top models from OpenAI, Anthropic, and Google. One key, one bill, no provider accounts needed. [Read the blog](https://www.browserbase.com/blog/model-gateway)
+</Callout>
+
+## Model Gateway
+
+Model Gateway lets you use Stagehand without wiring up model providers yourself. Instead of managing separate API keys for each provider, just pass your Browserbase API key and pick a model. Browserbase routes the request to the upstream provider for you.
+
+### Setup
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "openai/gpt-5",
+});
+
+await stagehand.init();
+```
+
+When only a Browserbase API key is provided (without a provider-specific API key), Stagehand automatically routes model requests through Model Gateway. No additional configuration is needed.
+
+<Note>
+  Model Gateway requires Browserbase-hosted browsers. It does not work with `env: "LOCAL"`.
+</Note>
+
+### Switching models
+
+With Model Gateway, switching between providers is just a config change — no new accounts, API keys, or code rewiring required:
+
+<Tabs>
+<Tab title="OpenAI">
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "openai/gpt-5",
+});
+```
+</Tab>
+<Tab title="Anthropic">
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "anthropic/claude-sonnet-4-6",
+});
+```
+</Tab>
+<Tab title="Google">
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "google/gemini-3-flash-preview",
+});
+```
+</Tab>
+</Tabs>
+
+### Key benefits
+
+- **One key, one bill** — LLM inference, browser infrastructure, and caching all run through your Browserbase API key.
+- **Market-price tokens** — We charge the same price as going direct to the provider. No markup.
+- **Built-in reliability** — Retries, backoff, and rate limit handling are managed for you.
+- **No tier-gating** — Access new models immediately without hitting provider spend thresholds.
+- **Action caching** — Model Gateway works with Stagehand's [managed action caching](/v3/best-practices/caching), so repeated steps are reused instead of re-run.
+
+### Supported providers
+
+| Provider   | Example Model                  |
+| ---------- | ------------------------------ |
+| OpenAI     | `openai/gpt-5`                |
+| Anthropic  | `anthropic/claude-sonnet-4-6` |
+| Google     | `google/gemini-2.5-flash`     |
+
+<Tip>
+  Need a provider that isn't listed? [Reach out](https://www.browserbase.com/contact) — we're happy to work with teams on additional model support.
+</Tip>
+

+
+## Configuration Setup
+
+### Quick Start
+
+<Tip>
+  Set your API key in `.env` and Stagehand handles the rest. No explicit
+  configuration needed!
+</Tip>
+
+Get started with Google Gemini (recommended for speed and cost):
+
+<CodeGroup>
+```typescript TypeScript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "google/gemini-2.5-flash"
+  // API key auto-loads from GOOGLE_GENERATIVE_AI_API_KEY - set in your .env
+});
+
+await stagehand.init();
+
+```
+</CodeGroup>
+
+
+---
+
+### First Class Models
+
+Use any model from the following supported providers.

+## Advanced Options
+
+### Agent Models (with CUA Support)
+
+**Default**
+
+The Stagehand agent by default uses the same model passed to Stagehand. All models ([first class](/v3/configuration/models#first-class-models) and [custom](/v3/configuration/models#custom-models)) are supported. Here's an example with Gemini:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "google/gemini-2.5-flash",
+  // GOOGLE_GENERATIVE_AI_API_KEY is auto-loaded from .env
+  // ... other stagehand options
+});
+
+// Agent will use google/gemini-2.5-flash
+const agent = stagehand.agent();
+```
+
+**Override (with CUA support)**
+
+However, the stagehand agent also accepts a `model` parameter, which accepts any [first class](/v3/configuration/models#first-class-models) model, including [computer use agents (CUA)](/v3/configuration/models#agent-models-with-cua-support). This is useful when you'd like the agent to use a different model than the one passed to Stagehand.
+
+<Tip>
+  To use a CUA model, you must pass the `mode: "cua"` parameter to the `agent()` method. If a non-CUA model is used, whether specified in Stagehand or overridden in the `agent()` method, an error will be thrown.
+</Tip>
+
+<Warning>
+**Deprecation Notice:** The `cua: true` option is deprecated and will be removed in a future version. Use `mode: "cua"` instead.
+</Warning>
+
+<Tabs>
+<Tab title="Google CUA">
+```typescript
+const agent = stagehand.agent({

+
+<Note>
+  For overriding the agent API key, using a corporate proxy, adding provider-specific options, or other advanced use cases, the agent model can also take the form of an object. To learn more, see the [Agent Reference](/v3/references/agent).

+### Custom Endpoints
+
+If you need Azure OpenAI deployments or enterprise deployments.
+
+<Tabs>
+<Tab title="OpenAI">
+
+For OpenAI, you can pass configuration directly without using `llmClient` using the `model` parameter:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: {
+    modelName: "openai/gpt-5",
+    apiKey: process.env.OPENAI_API_KEY,
+    baseURL: "https://custom-openai-endpoint.com/v1"
+  }
+});
+```
+
+</Tab>
+
+<Tab title="Anthropic">
+
+For Anthropic, you can pass configuration directly without using `llmClient` using the `model` parameter:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: {
+    modelName: "anthropic/claude-haiku-4-5",
+    apiKey: process.env.ANTHROPIC_API_KEY,
+    baseURL: "https://custom-anthropic-endpoint.com",
+  },
+});
+```
+
+  </Tab>
+<Tab title="All Other Providers">
+For all other providers, use `llmClient`. Here's an example with Hugging Face:
+
+```typescript
+// pnpm add @ai-sdk/huggingface
+
+import { createHuggingFace } from "@ai-sdk/huggingface";
+import { AISdkClient } from "@browserbasehq/stagehand";
+
+const huggingFaceProvider = createHuggingFace({
+  apiKey: process.env.HUGGINGFACE_API_KEY,
+  baseURL: "https://custom-huggingface-endpoint.com",
+});
+
+const huggingFaceClient = new AISdkClient({
+  model: huggingFaceProvider("meta-llama/Llama-3.1-8B-Instruct"),
+});
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  llmClient: huggingFaceClient,
+});
+```
+
+</Tab>
+</Tabs>
+
+---
+
+### AI Gateway
+
+The [Vercel AI Gateway](https://vercel.com/docs/ai-gateway) lets you access models from multiple providers (OpenAI, Anthropic, Google, and more) through a single API key and interface. No extra provider SDKs or per-provider API keys needed.
+
+<Tip>
+  The AI Gateway is built into the `ai` package that Stagehand already uses -- no additional dependencies required.
+</Tip>
+
+**Key benefits:**
+- Access models from all major providers with a single `AI_GATEWAY_API_KEY`
+- Automatic provider fallback and dynamic routing based on uptime and latency
+- Usage tracking and observability through the Vercel dashboard
+- Bring Your Own Key (BYOK) support for existing provider credentials
+
+<Tabs>
+<Tab title="Simple">
+
+Use the `gateway/` prefix followed by the provider and model name:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "gateway/openai/gpt-5"
+  // API key auto-loads from AI_GATEWAY_API_KEY - set in your .env
+});
+
+await stagehand.init();
+```
+
+Works with any model available on the gateway:
+
+```typescript
+// Anthropic via gateway
+model: "gateway/anthropic/claude-sonnet-4.5"
+
+// Google via gateway
+model: "gateway/google/gemini-3-flash-preview"
+```
+
+</Tab>
+<Tab title="Custom Config">
+
+Pass the API key and optional base URL explicitly using the model object format:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: {
+    modelName: "gateway/openai/gpt-5",
+    apiKey: process.env.AI_GATEWAY_API_KEY,
+    baseURL: "https://ai-gateway.vercel.sh/v3/ai" // optional custom endpoint
+  }
+});
+
+await stagehand.init();
+```
+
+</Tab>
+</Tabs>
+
+[View all available AI Gateway models →](https://vercel.com/docs/ai-gateway/models-and-providers)
+
+---
+
+### Extending the AI SDK Client
+
+For advanced use cases like custom retries or caching logic, you can extend the `AISdkClient`:
+
+```typescript
+import { LLMClient } from "@browserbasehq/stagehand";
+
+class CustomRetryClient extends LLMClient {
+  async createChatCompletion(options) {
+    let retries = 3;
+    while (retries > 0) {
+      try {
+        return await super.createChatCompletion(options);
+      } catch (error) {
+        retries--;
+        if (retries === 0) throw error;
+        await new Promise((r) => setTimeout(r, 1000 * (4 - retries)));
+      }
+    }
+  }
+}
+```
+
+<Tip>
+  Need custom caching? Consider using built-in [caching
+  feature](/v3/best-practices/caching).
+</Tip>
+
+---
+
+### Legacy Model Format
+
+<Tip>
+**Recommendation:** Use `provider/model` format. Example:
+- `model: "openai/gpt-4o"` (recommended)
+- `model: "gpt-4o"` (legacy)
+
+</Tip>
+
+The following models work without the `provider/` prefix in the model parameter as part of legacy support:
+
+<AccordionGroup title="Legacy Model Format">

+
+
+Stagehand provides powerful observability features to help you monitor, track performance, and analyze your browser automation workflows. Focus on session monitoring, resource usage, and operational insights for both Browserbase and local environments.
+
+## Browserbase Session Monitoring
+
+When running on Browserbase, you gain access to comprehensive cloud-based monitoring and session management through the Browserbase API and dashboard.
+
+<div style={{ textAlign: "center" }}>
+  <img src="/media/observability.gif" alt="Browserbase Session Observability" width="400" />
+</div>
+
+### Live Session Visibility
+
+Browserbase provides real-time visibility into your automation sessions:
+
+**Session Dashboard Features**
+- Real-time browser screen recording and replay
+- Network request monitoring with detailed timing
+- JavaScript console logs and error tracking
+- CPU and memory usage metrics
+- Session status and duration tracking
+
+**Session Management & API Access**
+```typescript

+
+const browserbase = new Browserbase({
+  apiKey: process.env.BROWSERBASE_API_KEY,
+});
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE"
+});
+
+await stagehand.init();
+
+const sessionInfo = await browserbase.sessions.retrieve(stagehand.sessionId);
+
+console.log("Session status:", sessionInfo.status);
+console.log("Session region:", sessionInfo.region);
+console.log("CPU usage:", sessionInfo.avgCpuUsage);
+console.log("Memory usage:", sessionInfo.memoryUsage);

+
+### Session Monitoring & Filtering
+
+Query and monitor sessions by status and metadata:
+
+```typescript
+import { Browserbase } from "@browserbasehq/sdk";
+
+const browserbase = new Browserbase({
+  apiKey: process.env.BROWSERBASE_API_KEY,
+});
+
+// List sessions with filtering
+async function getFilteredSessions() {
+  const sessions = await browserbase.sessions.list({
+    status: 'RUNNING'
+  });
+  
+  return sessions.map(session => ({
+    id: session.id,
+    status: session.status, // RUNNING, COMPLETED, ERROR, TIMED_OUT
+    startedAt: session.startedAt,
+    endedAt: session.endedAt,
+    region: session.region,
+    avgCpuUsage: session.avgCpuUsage,
+    memoryUsage: session.memoryUsage,
+    proxyBytes: session.proxyBytes,
+    userMetadata: session.userMetadata
+  }));
+}
+
+// Query sessions by metadata
+async function querySessionsByMetadata(query: string) {
+  const sessions = await browserbase.sessions.list({
+    q: query
+  });
+  
+  return sessions;
+}
+```
+
+## Local Environment Monitoring
+
+For local development, Stagehand provides performance monitoring and resource tracking capabilities directly on your machine.
+
+### Performance Tracking
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  verbose: 1, // Monitor performance without debug noise
+});
+
+await stagehand.init();
+
+// Track local automation metrics
+const startTime = Date.now();
+const initialMetrics = await stagehand.metrics;
+
+// ... perform automation tasks
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+await stagehand.act("click button");
+await stagehand.extract({ instruction: "get data", schema: DataSchema });
+
+const finalMetrics = await stagehand.metrics;
+const executionTime = Date.now() - startTime;
+
+console.log('Local Performance Summary:', {
+  executionTime: `${executionTime}ms`,
+  totalTokens: finalMetrics.totalPromptTokens + finalMetrics.totalCompletionTokens,
+  totalInferenceTime: `${finalMetrics.totalInferenceTimeMs}ms`,
+  tokensPerSecond: ((finalMetrics.totalPromptTokens + finalMetrics.totalCompletionTokens) / (executionTime / 1000)).toFixed(2)
+});
+```
+
+## Resource Usage Monitoring
+
+When running locally, monitor system resource usage and browser performance:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import * as os from 'os';
+import { performance } from 'perf_hooks';
+
+class LocalResourceMonitor {
+  private cpuUsage: number[] = [];
+  private memoryUsage: number[] = [];
+  
+  startMonitoring() {
+    const interval = setInterval(() => {
+      // Track system resources
+      const memUsage = process.memoryUsage();
+      this.memoryUsage.push(memUsage.heapUsed / 1024 / 1024); // MB
+      
+      // Track CPU (simplified)
+      const loadAvg = os.loadavg()[0];
+      this.cpuUsage.push(loadAvg);
+    }, 1000);
+    
+    return interval;
+  }
+  
+  getResourceSummary() {
+    return {
+      avgMemoryUsage: this.memoryUsage.reduce((a, b) => a + b, 0) / this.memoryUsage.length,
+      peakMemoryUsage: Math.max(...this.memoryUsage),
+      avgCpuLoad: this.cpuUsage.reduce((a, b) => a + b, 0) / this.cpuUsage.length,
+      totalDataPoints: this.cpuUsage.length
+    };
+  }
+}
+
+const monitor = new LocalResourceMonitor();
+const interval = monitor.startMonitoring();
+
+const stagehand = new Stagehand({ env: "LOCAL" });
+
+// ... run automation
+
+clearInterval(interval);
+console.log('Resource Usage:', monitor.getResourceSummary());
+```
+
+
+  <Card title="LLM Usage" icon="chart-line" href="/v3/basics/evals">
+    Monitor token usage, costs, and speed. Set up automated alerting for critical failures. Implement cost tracking across different environments. Use session analytics to optimize automation workflows.
+  </Card>
+
+
+## Real-Time Metrics & Monitoring
+
+### Basic Usage Tracking
+
+Monitor your automation's resource usage in real-time with `stagehand.metrics`:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "BROWSERBASE" });
+await stagehand.init();
+
+// Metrics are async in V3
+const metrics = await stagehand.metrics;
+console.log(metrics);
+
+// Monitor during automation
+const startTime = Date.now();
+const initialMetrics = await stagehand.metrics;
+
+// ... perform automation tasks
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+await stagehand.act("click the login button");
+const data = await stagehand.extract({
+  instruction: "extract user info",
+  schema: UserSchema
+});
+
+const finalMetrics = await stagehand.metrics;
+const executionTime = Date.now() - startTime;
+
+console.log('Automation Summary:', {
+  totalTokens: finalMetrics.totalPromptTokens + finalMetrics.totalCompletionTokens,
+  executionTime: `${executionTime}ms`,
+  avgInferenceTime: `${finalMetrics.totalInferenceTimeMs / 3}ms`,
+});
+```
+
+### Understanding Metrics Data
+
+The metrics object provides detailed breakdown by Stagehand operation:
+
+```typescript
+interface StagehandMetrics {
+  // Act operation metrics
+  actPromptTokens: number;
+  actCompletionTokens: number;
+  actReasoningTokens: number;
+  actCachedInputTokens: number;
+  actInferenceTimeMs: number;
+
+  // Extract operation metrics
+  extractPromptTokens: number;
+  extractCompletionTokens: number;
+  extractReasoningTokens: number;
+  extractCachedInputTokens: number;
+  extractInferenceTimeMs: number;
+
+  // Observe operation metrics
+  observePromptTokens: number;
+  observeCompletionTokens: number;
+  observeReasoningTokens: number;
+  observeCachedInputTokens: number;
+  observeInferenceTimeMs: number;
+
+  // Agent operation metrics
+  agentPromptTokens: number;
+  agentCompletionTokens: number;
+  agentReasoningTokens: number;
+  agentCachedInputTokens: number;
+  agentInferenceTimeMs: number;
+
+  // Cumulative totals
+  totalPromptTokens: number;
+  totalCompletionTokens: number;
+  totalReasoningTokens: number;
+  totalCachedInputTokens: number;
+  totalInferenceTimeMs: number;
+}
+```
+
+**Example metrics output:**
+
+```typescript
+const metrics = await stagehand.metrics;
+console.log(metrics);
+
+// {
+//   actPromptTokens: 4011,
+//   actCompletionTokens: 51,
+//   actReasoningTokens: 12,
+//   actCachedInputTokens: 0,
+//   actInferenceTimeMs: 1688,
+//   extractPromptTokens: 4200,
+//   extractCompletionTokens: 243,
+//   extractReasoningTokens: 18,
+//   extractCachedInputTokens: 0,
+//   extractInferenceTimeMs: 4297,
+//   observePromptTokens: 347,
+//   observeCompletionTokens: 43,
+//   observeReasoningTokens: 5,
+//   observeCachedInputTokens: 0,
+//   observeInferenceTimeMs: 903,
+//   agentPromptTokens: 0,
+//   agentCompletionTokens: 0,
+//   agentReasoningTokens: 0,
+//   agentCachedInputTokens: 0,
+//   agentInferenceTimeMs: 0,
+//   totalPromptTokens: 8558,
+//   totalCompletionTokens: 337,
+//   totalReasoningTokens: 35,
+//   totalCachedInputTokens: 0,
+//   totalInferenceTimeMs: 6888
+// }
+```

+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+You're likely using AI to write code, and there's a **right and wrong way to do it.** This page is a collection of rules, configs, and copy‑paste snippets to allow your AI agents/assistants to write performant, Stagehand code as fast as possible. 
+
+## Quickstart
+
+<CardGroup cols={2}>
+  <Card title="Add MCP servers" icon="screwdriver-wrench">
+    Configure Browserbase (Stagehand), Context7, DeepWiki, and Stagehand Docs in your MCP client. 
+  </Card>

+
+## Using MCP Servers
+
+MCP (Model Context Protocol) servers act as intermediaries that connect AI systems to external data sources and tools. These servers enable your coding assistant to access real-time information, execute tasks, and retrieve structured data to enhance code generation accuracy.
+
+The following **MCP servers** provide specialized access to Stagehand documentation and related resources:
+
+<Accordion title="Context7 by Upstash" icon="database">
+Provides semantic search across documentation and codebase context. Context7 enables AI assistants to find relevant code patterns, examples, and implementation details from your project history. It maintains contextual understanding of your development workflow and can surface related solutions from previous work.
+
+**Installation:**
+```json
+{
+  "mcpServers": {
+    "context7": {
+      "command": "npx",
+      "args": ["-y", "@upstash/context7-mcp"]
+    }
+  }
+}
+```
+</Accordion>
+
+<Accordion title="DeepWiki by Cognition" icon="book-open">
+Offers deep indexing of GitHub repositories and documentation. DeepWiki allows AI agents to understand project architecture, API references, and best practices from the entire Stagehand ecosystem. It provides comprehensive knowledge about repository structure, code relationships, and development patterns.
+
+**Installation:**
+```json
+{
+  "mcpServers": {
+    "deepwiki": {
+      "url": "https://mcp.deepwiki.com/mcp"
+    }
+  }
+}
+```
+</Accordion>
+
+<Accordion title="Stagehand Docs by Mintlify" icon="mintbit">
+Direct access to official Stagehand documentation. This MCP server provides AI assistants with up-to-date API references, configuration options, and usage examples for accurate code generation. Mintlify auto-generates this server from the official docs, ensuring your AI assistant always has the latest information.
+
+**Usage:**
+```json
+{
+  "mcpServers": {
+    "stagehand-docs": {
+      "url": "https://docs.stagehand.dev/mcp"
+    }
+  }
+}
+```
+</Accordion>
+
+**How MCP Servers Enhance Your Development:**
+- **Real-time Documentation Access**: AI assistants can query the latest Stagehand docs, examples, and best practices
+- **Context-Aware Code Generation**: Servers provide relevant code patterns and configurations based on your specific use case
+- **Reduced Integration Overhead**: Standardized protocol eliminates the need for custom integrations with each documentation source
+- **Enhanced Accuracy**: AI agents receive structured, up-to-date information rather than relying on potentially outdated training data
+
+<Tip>
+**Prompting tip:** 
+Explicitly ask your coding agent/assistant to use these MCP servers to fetch relevant information from the docs so they have better context and know how to write proper Stagehand code. 
+
+ie. **"Use the stagehand-docs MCP to fetch the act/observe guidelines, then generate code that follows them. Prefer cached observe results."**
+</Tip>
+
+## Editor rule files (copy‑paste)
+
+Drop these in `.cursorrules`, `windsurfrules`, `claude.md`, or any agent rule framework:

+# Stagehand Project
+
+This is a project that uses Stagehand V3, a browser automation framework with AI-powered `act`, `extract`, `observe`, and `agent` methods.
+
+The main class can be imported as `Stagehand` from `@browserbasehq/stagehand`.
+
+**Key Classes:**
+
+- `Stagehand`: Main orchestrator class providing `act`, `extract`, `observe`, and `agent` methods
+- `context`: A `V3Context` object that manages browser contexts and pages
+- `page`: Individual page objects accessed via `stagehand.context.pages()[i]` or created with `stagehand.context.newPage()`
+
+## Initialize
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "LOCAL", // or "BROWSERBASE"
+  verbose: 2, // 0, 1, or 2
+  model: "openai/gpt-4.1-mini", // or any supported model
+});
+
+await stagehand.init();
+
+// Access the browser context and pages
+const page = stagehand.context.pages()[0];
+const context = stagehand.context;
+
+// Create new pages if needed
+const page2 = await stagehand.context.newPage();
+```
+
+## Act
+
+Actions are called on the `stagehand` instance (not the page). Use atomic, specific instructions:
+
+```typescript
+// Act on the current active page
+await stagehand.act("click the sign in button");
+
+// Act on a specific page (when you need to target a page that isn't currently active)
+await stagehand.act("click the sign in button", { page: page2 });
+```
+
+**Important:** Act instructions should be atomic and specific:
+
+- ✅ Good: "Click the sign in button" or "Type 'hello' into the search input"
+- ❌ Bad: "Order me pizza" or "Type in the search bar and hit enter" (multi-step)
+
+### Observe + Act Pattern (Recommended)
+
+Cache the results of `observe` to avoid unexpected DOM changes:
+
+```typescript
+const instruction = "Click the sign in button";
+
+// Get candidate actions
+const actions = await stagehand.observe(instruction);
+
+// Execute the first action
+await stagehand.act(actions[0]);
+```
+
+To target a specific page:
+
+```typescript
+const actions = await stagehand.observe("select blue as the favorite color", {
+  page: page2,
+});
+await stagehand.act(actions[0], { page: page2 });
+```
+
+## Extract
+
+Extract data from pages using natural language instructions. The `extract` method is called on the `stagehand` instance.
+
+### Basic Extraction (with schema)
+
+```typescript
+import { z } from "zod";
+
+// Extract with explicit schema
+const data = await stagehand.extract(
+  "extract all apartment listings with prices and addresses",
+  z.object({
+    listings: z.array(
+      z.object({
+        price: z.string(),
+        address: z.string(),
+      }),
+    ),
+  }),
+);
+
+console.log(data.listings);
+```
+
+### Simple Extraction (without schema)
+
+```typescript
+// Extract returns a default object with 'extraction' field
+const result = await stagehand.extract("extract the sign in button text");
+
+console.log(result);
+// Output: { extraction: "Sign in" }
+
+// Or destructure directly
+const { extraction } = await stagehand.extract(
+  "extract the sign in button text",
+);
+console.log(extraction); // "Sign in"
+```
+
+### Targeted Extraction
+
+Extract data from a specific element using a selector:
+
+```typescript
+const reason = await stagehand.extract(
+  "extract the reason why script injection fails",
+  z.string(),
+  { selector: "/html/body/div[2]/div[3]/iframe/html/body/p[2]" },
+);
+```
+
+### URL Extraction
+
+When extracting links or URLs, use `z.string().url()`:
+
+```typescript
+const { links } = await stagehand.extract(
+  "extract all navigation links",
+  z.object({
+    links: z.array(z.string().url()),
+  }),
+);
+```
+
+### Extracting from a Specific Page
+
+```typescript
+// Extract from a specific page (when you need to target a page that isn't currently active)
+const data = await stagehand.extract(
+  "extract the placeholder text on the name field",
+  { page: page2 },
+);
+```
+
+## Observe
+
+Plan actions before executing them. Returns an array of candidate actions:
+
+```typescript
+// Get candidate actions on the current active page
+const [action] = await stagehand.observe("Click the sign in button");
+
+// Execute the action
+await stagehand.act(action);
+```
+
+Observing on a specific page:
+
+```typescript
+// Target a specific page (when you need to target a page that isn't currently active)
+const actions = await stagehand.observe("find the next page button", {
+  page: page2,
+});
+await stagehand.act(actions[0], { page: page2 });
+```
+
+## Agent
+
+Use the `agent` method to autonomously execute complex, multi-step tasks.
+
+### Basic Agent Usage
+
+```typescript
+const page = stagehand.context.pages()[0];
+await page.goto("https://www.google.com");
+
+const agent = stagehand.agent({
+  model: "google/gemini-2.0-flash",
+  executionModel: "google/gemini-2.0-flash",
+});
+
+const result = await agent.execute({
+  instruction: "Search for the stock price of NVDA",
+  maxSteps: 20,
+});
+
+console.log(result.message);
+```
+
+### Computer Use Agent (CUA)
+
+For more advanced scenarios using computer-use models:
+
+```typescript
+const agent = stagehand.agent({
+  mode: "cua", // Enable Computer Use Agent mode
+  model: "anthropic/claude-sonnet-4-6",
+  // or "google/gemini-2.5-computer-use-preview-10-2025"
+  systemPrompt: `You are a helpful assistant that can use a web browser.
+    Do not ask follow up questions, the user will trust your judgement.`,
+});
+
+await agent.execute({
+  instruction: "Apply for a library card at the San Francisco Public Library",
+  maxSteps: 30,
+});
+```
+
+### Agent with Custom Model Configuration
+
+```typescript
+const agent = stagehand.agent({
+  mode: "cua",
+  model: {
+    modelName: "google/gemini-2.5-computer-use-preview-10-2025",
+    apiKey: process.env.GEMINI_API_KEY,
+  },
+  systemPrompt: `You are a helpful assistant.`,
+});
+```
+
+### Agent with Integrations (MCP/External Tools)
+
+```typescript
+const agent = stagehand.agent({
+  integrations: [`https://mcp.exa.ai/mcp?exaApiKey=${process.env.EXA_API_KEY}`],
+  systemPrompt: `You have access to the Exa search tool.`,
+});
+```
+
+## Advanced Features
+
+### DeepLocator (XPath Targeting)
+
+Target specific elements across shadow DOM and iframes:
+
+```typescript
+await page
+  .deepLocator("/html/body/div[2]/div[3]/iframe/html/body/p")
+  .highlight({
+    durationMs: 5000,
+    contentColor: { r: 255, g: 0, b: 0 },
+  });
+```
+
+### Multi-Page Workflows
+
+```typescript
+const page1 = stagehand.context.pages()[0];
+await page1.goto("https://example.com");
+
+const page2 = await stagehand.context.newPage();
+await page2.goto("https://example2.com");
+
+// Act/extract/observe operate on the current active page by default
+// Pass { page } option to target a specific page
+await stagehand.act("click button", { page: page1 });
+await stagehand.extract("get title", { page: page2 });
+```

+This is a project that uses [Stagehand Python](https://github.com/browserbase/stagehand-python), which provides AI-powered browser automation with `act`, `extract`, and `observe` methods.
+
+`Stagehand` is a class that provides configuration and browser automation capabilities with:
+- Pages accessed via `stagehand.context.pages()` or `stagehand.context.activePage()`
+- `stagehand.context`: A StagehandContext object (extends Playwright BrowserContext)
+- `stagehand.agent()`: Create AI-powered agents for autonomous multi-step workflows
+- `stagehand.init()`: Initialize the browser session
+- `stagehand.close()`: Clean up resources
+
+`Page` extends Playwright's Page class with AI-powered methods:
+- `act()`: Perform actions on web elements using natural language
+- `extract()`: Extract structured data from pages using schemas
+- `observe()`: Plan actions and get selectors before executing
+
+`Agent` provides autonomous Computer Use Agent capabilities:
+- `execute()`: Perform complex multi-step tasks using natural language instructions
+
+Use the following rules to write code for this project.
+
+- To plan an instruction like "click the sign in button", use Stagehand `observe` to get the action to execute.
+
+You can also pass in the following params:
+
+- The result of `observe` is a list of `ObserveResult` objects that can directly be used as params for `act` like this:
+  
+- When writing code that needs to extract data from the page, use Stagehand `extract`. Use Pydantic models for schemas:
+
+## Initialize
+
+### Configuration Options
+
+Key configuration options in `StagehandConfig`:
+
+## Act
+
+You can act directly with string instructions:
+
+Use variables for dynamic form filling:
+
+**Best Practices:**
+- Cache the results of `observe` to avoid unexpected DOM changes
+- Keep actions atomic and specific (e.g., "Click the sign in button" not "Sign in to the website")
+- Use specific, descriptive instructions
+
+Act `action` should be as atomic and specific as possible, i.e. "Click the sign in button" or "Type 'hello' into the search input".
+AVOID actions that are more than one step, i.e. "Order me pizza" or "Send an email to Paul asking him to call me".
+
+## Extract
+
+### Simple String Extraction
+
+### Structured Extraction with Schema (Recommended)
+Always use Pydantic models for structured data extraction:
+
+### Array Extraction
+For arrays, use List types:
+
+### Complex Object Extraction
+For more complex data structures:
+
+## Agent System
+
+Stagehand provides an Agent System for autonomous web browsing using Computer Use Agents (CUA).
+
+### Creating Agents
+
+### Agent Execution
+
+**Best Practices:**
+- Be specific with instructions: `"Fill out the contact form with name 'John Doe' and submit it"`
+- Break down complex tasks into smaller steps
+- Use error handling with try/except blocks
+- Combine agents for navigation with traditional methods for precise data extraction
+
+## Project Structure Best Practices
+
+- Store configurations in environment variables or config files
+- Use async/await patterns consistently
+- Implement main automation logic in async functions
+- Use async context managers for resource management
+- Use type hints and Pydantic models for data validation
+- Handle exceptions appropriately with try/except blocks
+``````
+
+</Accordion>
+
+## Security notes
+
+- Do not embed secrets in docs or rule files; use env vars in MCP configs.
+- Avoid broad actions that may trigger unintended navigation; prefer `observe` first.

+title: Introducing Stagehand
+sidebarTitle: Introduction
+description: Developers use Stagehand to reliably automate the web.
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
+## The Problem with Browser Automation
+
+Traditional frameworks like Playwright and Puppeteer force you to write brittle scripts that break with every UI change. Web agents promise to solve this with AI, but leave you at the mercy of unpredictable behavior.
+
+**You're stuck between two bad options:**
+- **Too brittle**: Traditional selectors break when websites change
+- **Too agentic**: AI agents are unpredictable and impossible to debug
+
+## Enter Stagehand
+
+Stagehand gives you the best of both worlds through four powerful primitives that let you choose exactly how much AI to use:
+

+  </Card>
+</CardGroup>
+
+```typescript
+// Act - Execute natural language actions
+await stagehand.act("click the login button");
+
+// Extract - Pull structured data
+const price = await stagehand.extract(
+  "extract the price",
+  z.number()
+);
+
+// Observe - Discover available actions
+const actions = await stagehand.observe("find submit buttons");
+
+// Agent - Automate entire workflows
+const agent = stagehand.agent({
+  mode: "cua",
+  model: "google/gemini-2.5-computer-use-preview-10-2025",
+});
+await agent.execute("apply for this job");
+```
+
+
+## Why Developers Choose Stagehand
+
+- **Precise Control**: Mix AI-powered actions with deterministic code. You decide exactly how much AI to use.
+
+- **Actually Repeatable**: Save and replay actions exactly. No more "it worked on my machine" with browser automations.
+
+- **Maintainable at Scale**: One script can automate multiple websites. When sites change, your automations adapt.
+
+- **Composable Tools**: Choose your level of automation with Act, Extract, Observe, and Agent.
+

+
+The quickest way to start with Stagehand is with our CLI. It scaffolds a ready‑to‑run Stagehand app with sensible defaults, and an example script. You can also try Stagehand using our [MCP server](/v3/integrations/mcp/introduction).
+
+<Note>
+This quickstart is for **TypeScript**. For other languages, change the language selector in the top left corner.
+</Note>
+
+## 1) Create a sample project
+
+<CodeGroup>
+```bash Bash
+npx create-browser-app
+```
+</CodeGroup>
+
+## 2) Run it
+
+Follow the CLI prompts to enter the project directory and add your API keys. Then run the example script.
+
+<CodeGroup>
+```bash Bash
+cd my-stagehand-app # Enter the project directory
+cp .env.example .env  # Add your API keys
+npm start # Run the example script
+```
+</CodeGroup>
+
+## 3) Use Stagehand (act, extract, observe)
+
+The scaffold includes an index.ts file that contains the example script. Here's what it looks like:
+
+<CodeGroup>
+```typescript TypeScript
+import "dotenv/config";
+import { Stagehand } from "@browserbasehq/stagehand";
+
+async function main() {
+  const stagehand = new Stagehand({
+    env: "BROWSERBASE"
+  });
+
+  await stagehand.init();
+
+  console.log(`Stagehand Session Started`);
+  console.log(`Watch live: https://browserbase.com/sessions/${stagehand.browserbaseSessionID}`);
+
+  const page = stagehand.context.pages()[0];
+
+  await page.goto("https://stagehand.dev");
+
+  const extractResult = await stagehand.extract("Extract the value proposition from the page.");
+  console.log(`Extract result:\n`, extractResult);
+
+  await stagehand.act("Click the 'Evals' button.");
+
+  const observeResult = await stagehand.observe("What can I click on this page?");
+  console.log(`Observe result:\n`, observeResult);
+
+  const agent = stagehand.agent({
+    mode: "cua",
+    model: "google/gemini-2.5-computer-use-preview-10-2025",
+    systemPrompt: "You're a helpful assistant that can control a web browser.",
+  });
+
+  const agentResult = await agent.execute("What is the most accurate model to use in Stagehand?");
+  console.log(`Agent result:\n`, agentResult);
+
+  await stagehand.close();
+}
+
+main().catch((err) => {
+  console.error(err);
+  process.exit(1);
+});
+
+```
+</CodeGroup>
+
+<Tip>
+To use, set provider keys in `.env` (e.g., `OPENAI_API_KEY`). For cloud browsers, add `BROWSERBASE_API_KEY`.

+  Clone the [GitHub repo](https://github.com/browserbase/convex-stagehand) to get started with Stagehand in Convex.
+</Card>
+
+## Installation
+
+Install the convex-stagehand component and Zod for schema validation:
+
+```bash
+npm install @browserbasehq/convex-stagehand zod
+```
+
+## Configuration
+
+Add the Stagehand component to your `convex/convex.config.ts`:
+
+```typescript convex/convex.config.ts
+import { defineApp } from "convex/server";
+import stagehand from "@browserbasehq/convex-stagehand/convex.config";
+
+const app = defineApp();
+app.use(stagehand, { name: "stagehand" });
+export default app;
+```
+
+## Environment Variables
+
+Set the following environment variables in your [Convex Dashboard](https://dashboard.convex.dev):
+
+| Variable | Description |
+|----------|-------------|
+| `BROWSERBASE_API_KEY` | Your Browserbase API key |
+| `MODEL_API_KEY` | API key for your LLM provider (OpenAI, Anthropic, etc.) |
+
+## Basic Usage
+
+### Initialize the Client
+
+Create a Stagehand instance in your Convex action:
+
+```typescript convex/actions.ts
+"use node";
+
+import { Stagehand } from "@browserbasehq/convex-stagehand";
+import { components } from "./_generated/api";
+import { action } from "./_generated/server";
+import { z } from "zod";
+
+const stagehand = new Stagehand(components.stagehand, {
+  browserbaseApiKey: process.env.BROWSERBASE_API_KEY!,
+  modelApiKey: process.env.MODEL_API_KEY!,
+});
+```
+
+### Extract Data
+
+Extract structured data from a web page using natural language instructions and Zod schemas:
+
+```typescript
+export const extractProducts = action({
+  handler: async (ctx) => {
+    const data = await stagehand.extract(ctx, {
+      url: "https://example.com/products",
+      instruction: "Extract all product names and prices",
+      schema: z.object({
+        products: z.array(z.object({
+          name: z.string(),
+          price: z.string(),
+        }))
+      })
+    });
+
+    return data.products;
+  }
+});
+```
+
+### Perform Actions
+
+Execute browser interactions using plain English:
+
+```typescript
+export const loginToSite = action({
+  handler: async (ctx) => {
+    const result = await stagehand.act(ctx, {
+      url: "https://example.com/login",
+      action: "Click the login button and wait for the page to load"
+    });
+
+    return result;
+  }
+});
+```
+
+### Observe Elements
+
+Identify interactive elements on a page:
+
+```typescript
+export const findNavLinks = action({
+  handler: async (ctx) => {
+    const actions = await stagehand.observe(ctx, {
+      url: "https://example.com",
+      instruction: "Find all clickable navigation links"
+    });
+
+    return actions;
+  }
+});
+```
+
+### Run Autonomous Tasks
+
+Use the agent API for complex multi-step workflows:
+
+```typescript
+export const searchAndExtract = action({
+  handler: async (ctx) => {
+    const result = await stagehand.agent(ctx, {
+      url: "https://google.com",
+      instruction: "Search for 'convex database' and extract the top 3 results",
+      options: { maxSteps: 10 }
+    });
+
+    return result;
+  }
+});
+```
+
+## Session Management
+
+For workflows that span multiple operations, you can reuse browser sessions:
+
+```typescript
+export const multiStepWorkflow = action({
+  handler: async (ctx) => {
+    // Start a session
+    const session = await stagehand.startSession(ctx, {
+      url: "https://example.com",
+      options: { timeout: 30000, waitUntil: "networkidle" }
+    });
+
+    // Perform multiple operations with the same session
+    await stagehand.act(ctx, {
+      sessionId: session.sessionId,
+      action: "Click the login button"
+    });
+
+    const data = await stagehand.extract(ctx, {
+      sessionId: session.sessionId,
+      instruction: "Extract the user profile information",
+      schema: z.object({
+        name: z.string(),
+        email: z.string(),
+      })
+    });
+
+    // End the session
+    await stagehand.endSession(ctx, { sessionId: session.sessionId });
+
+    return data;
+  }
+});
+```
+
+Session persistence allows you to preserve authentication state and cookies between operations.
+
+## Model Configuration
+
+The default model is `openai/gpt-4o`. You can configure alternative providers:
+
+```typescript
+const stagehand = new Stagehand(components.stagehand, {
+  browserbaseApiKey: process.env.BROWSERBASE_API_KEY!,
+  modelApiKey: process.env.ANTHROPIC_API_KEY!,
+  modelName: "anthropic/claude-sonnet-4-5-20250929",
+});
+```
+
+## Requirements
+
+- Convex 1.29.3 or later
+- A [Browserbase](https://browserbase.com) account with API credentials
+- An API key from a supported LLM provider (OpenAI, Anthropic, etc.)

+## Overview
+
+This guide shows you how to use Stagehand with Convex to create AI-powered browser automation within your Convex applications. By the end of this guide, you'll know how to:
+
+- Set up the convex-stagehand component in your Convex app
+- Extract structured data from web pages using natural language
+- Execute browser actions via plain English instructions
+- Build autonomous multi-step workflows with the agent API
+
+## When You'd Use This
+
+The Convex integration is perfect for scenarios where you need browser automation in serverless Convex functions:
+
+- **Data extraction pipelines**: Extract structured data from websites and store it directly in your Convex database
+- **Automated workflows**: Build background jobs that interact with web pages on behalf of users
+- **Form automation**: Automatically fill out and submit forms based on data from your Convex app
+- **Multi-step web processes**: Execute complex browser workflows that require decision-making and adaptation
+
+The integration wraps the Stagehand REST API to provide Convex actions with the ability to control cloud browsers via Browserbase:
+
+1. **Act**: Perform actions like clicking, typing, or navigating using natural language
+2. **Extract**: Extract structured data from web pages with Zod schemas
+3. **Observe**: Identify and analyze interactive elements on the page
+4. **Agent**: Run autonomous multi-step tasks with AI decision-making

+## Step 1: Install Dependencies
+
+Install the required packages for CrewAI and Stagehand integration:
+
+```bash
+pip install stagehand crewai crewai-tools
+```
+
+## Step 2: Configure Environment Variables
+
+You'll need API keys from three services:
+
+1. **Browserbase API Key**: Get this from your [Browserbase dashboard](https://www.browserbase.com/)
+2. **LLM API Key**: Get an API key from [OpenAI](https://platform.openai.com/api-keys) or [Anthropic](https://console.anthropic.com/)
+
+Store your API keys securely as environment variables:
+
+```bash
+BROWSERBASE_API_KEY="your-browserbase-api-key"
+OPENAI_API_KEY="your-openai-api-key"
+ANTHROPIC_API_KEY="your-anthropic-api-key"
+```
+
+## Step 3: Create Your First Agent
+
+Create a Python script with a basic CrewAI agent:
+
+```python
+import os
+from crewai import Agent, Task, Crew
+from crewai_tools import StagehandTool
+from stagehand.schemas import AvailableModel
+
+# Get API keys from environment
+browserbase_api_key = os.environ.get("BROWSERBASE_API_KEY")
+model_api_key = os.environ.get("OPENAI_API_KEY")  # or ANTHROPIC_API_KEY
+
+# Initialize the StagehandTool
+stagehand_tool = StagehandTool(
+    api_key=browserbase_api_key,
+    model_api_key=model_api_key,
+    model_name=AvailableModel.GPT_4O,  # or AvailableModel.CLAUDE_3_7_SONNET_LATEST
+)
+
+# Create an agent with the tool
+researcher = Agent(
+    role="Web Researcher",
+    goal="Find and summarize information from websites",
+    backstory="I'm an expert at finding information online.",
+    verbose=True,
+    tools=[stagehand_tool],
+)
+```
+
+## Step 4: Create and Run a Task
+
+Define a task for your agent and execute it:
+
+```python
+# Create a task that uses the tool
+research_task = Task(
+    description="Go to https://www.example.com and tell me what you see on the homepage.",
+    agent=researcher,
+)
+
+# Run the crew
+crew = Crew(
+    agents=[researcher],
+    tasks=[research_task],
+    verbose=True,
+)
+
+try:
+    result = crew.kickoff()
+    print(result)
+finally:
+    # Clean up resources
+    stagehand_tool.close()
+```
+
+## Step 5: Run Your Script
+
+Execute your Python script:
+
+```bash
+python your_crew_script.py
+```
+
+## Advanced Configuration
+
+Customize the StagehandTool behavior with additional parameters:
+
+```python
+stagehand_tool = StagehandTool(
+    api_key=browserbase_api_key,
+    model_api_key=model_api_key,
+    model_name=AvailableModel.CLAUDE_3_7_SONNET_LATEST,
+    dom_settle_timeout_ms=5000,  # Wait longer for DOM to settle
+    headless=True,  # Run browser in headless mode
+    self_heal=True,  # Attempt to recover from errors
+    wait_for_captcha_solves=True,  # Wait for CAPTCHA solving
+    verbose=1,  # Control logging verbosity (0-3)
+)
+```
+
+## Example Tasks

+## Overview
+
+This guide shows you how to use CrewAI with Browserbase to create intelligent agents that can automate web interactions. By the end of this guide, you'll know how to:
+
+- Set up CrewAI with the StagehandTool
+- Create agents that can interact with websites
+- Automate browser tasks using natural language instructions
+- Extract structured data from web pages
+
+## When You'd Use This
+
+The CrewAI integration is perfect for scenarios where you need intelligent web automation:
+
+- **Research automation**: Have agents research information across multiple websites
+- **Data collection**: Extract structured data from e-commerce sites, job boards, or news sites
+- **Form automation**: Automatically fill out and submit forms based on specific criteria
+- **Multi-step workflows**: Execute complex browser workflows that require decision-making
+
+The StagehandTool wraps the Stagehand Python SDK to provide CrewAI agents with the ability to control a real web browser and interact with websites using three core primitives:
+
+1. **Act**: Perform actions like clicking, typing, or navigating
+2. **Extract**: Extract structured data from web pages
+3. **Observe**: Identify and analyze elements on the page

+description: "Set up Stagehand with LangChain JS to create intelligent web automation agents"
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+This guide walks you through integrating Stagehand with LangChain JS to build powerful web automation workflows using natural language instructions.
+
+## Step 1: Install Dependencies
+
+Install the required packages for LangChain JS and Stagehand integration:
+
+```bash
+npm install @langchain/langgraph @langchain/community @langchain/core @browserbasehq/stagehand
+```
+
+## Step 2: Configure Environment Variables
+
+For remote browser automation, set up your Browserbase credentials:
+
+```bash
+BROWSERBASE_API_KEY="your-browserbase-api-key"
+```
+
+## Step 3: Create a Stagehand Instance
+
+Initialize Stagehand with your preferred configuration:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+// For local development
+const stagehand = new Stagehand({
+    env: "LOCAL",
+    verbose: 2,
+    enableCaching: false,
+});
+
+// For production with Browserbase
+const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    verbose: 1,
+    enableCaching: true,
+});
+```
+
+## Step 4: Generate the StagehandToolkit
+
+Create the toolkit that provides LangChain-compatible tools:
+
+```typescript
+import { StagehandToolkit } from '@langchain/community/agents/toolkits/stagehand';
+
+const stagehandToolkit = await StagehandToolkit.fromStagehand(stagehand);
+```
+
+## Step 5: Use Individual Tools
+
+The toolkit provides four specialized tools for web automation:
+
+### Available Tools
+
+- **stagehand_navigate**: Navigate to specific URLs
+- **stagehand_act**: Perform browser actions (clicking, typing, etc.)
+- **stagehand_extract**: Extract structured data using schemas  
+- **stagehand_observe**: Analyze page elements and possible actions
+
+### Basic Tool Usage
+
+```typescript
+import { z } from "zod";
+
+// Navigate to a website
+const navigateTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_navigate"
+);
+await navigateTool.invoke("https://www.google.com");
+
+// Perform an action
+const actionTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_act"
+);
+await actionTool.invoke('Search for "OpenAI"');
+
+// Observe the page
+const observeTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_observe"
+);
+const result = await observeTool.invoke(
+    "What actions can be performed on the current page?"
+);
+console.log(JSON.parse(result));
+
+// Extract structured data
+const extractTool = stagehandToolkit.tools.find(
+    (t) => t.name === "stagehand_extract"
+);
+const extractResult = await extractTool.invoke({
+    instruction: "Extract the main heading and description",
+    schema: z.object({
+        heading: z.string(),
+        description: z.string(),
+    }),
+});
+console.log(extractResult);
+```
+
+## Step 6: Build LangGraph Agents
+
+Integrate with LangGraph for complex automation workflows:
+
+```typescript
+import { createReactAgent } from "@langchain/langgraph/prebuilt";
+
+// Create an LLM
+const llm = new ChatOpenAI({
+    model: "gpt-4",
+    temperature: 0,
+});
+
+// Create an agent with Stagehand tools
+const agent = createReactAgent({
+    llm,
+    tools: stagehandToolkit.tools,
+});
+
+// Execute a complex workflow
+const result = await agent.invoke({
+    messages: [
+        {
+            role: "user", 
+            content: "Go to example.com, find the contact form, and extract all the form fields"
+        }
+    ]
+});
+```
+
+## Advanced Configuration
+
+### Custom Stagehand Configuration
+
+```typescript
+const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    verbose: 2,
+    enableCaching: true,
+    headless: true,
+    domSettleTimeoutMs: 5000,
+});
+```
+
+### Error Handling
+
+```typescript
+try {
+    const result = await agent.invoke({
+        messages: [{ role: "user", content: "Navigate to invalid-url.com" }]
+    });
+} catch (error) {
+    console.error("Automation failed:", error);
+} finally {
+    // Clean up resources
+    await stagehand.close();
+}
+```

+
+## Overview
+
+The Browserbase MCP Server brings powerful browser automation capabilities to MCP clients through the Model Context Protocol (MCP). Built on top of [Stagehand](https://docs.stagehand.dev/), this integration provides AI-powered web automation using natural language commands.
+
+<Info>
+  The hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http)
+  endpoint is served on Browserbase infrastructure.
+  You can also run the MCP server locally with STDIO, but we recommend the
+  hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http)
+  endpoint for most users.
+</Info>

+  One-click installation directly in Cursor
+</Card>
+
+You can also add Browserbase MCP to Claude Code with a single command. If your client supports HTTP request headers, prefer `Authorization: Bearer YOUR_BROWSERBASE_API_KEY`; otherwise, use the legacy query-parameter fallback:
+
+```bash
+claude mcp add --transport http browserbase "https://mcp.browserbase.com/mcp?browserbaseApiKey=YOUR_BROWSERBASE_API_KEY"
+```
+
+We support both local STDIO and hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http) (SHTTP). We recommend hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http) for most users.
+
+## Endpoint
+
+Hosted [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#streamable-http) endpoint (served on Browserbase infrastructure):
+

+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+## Overview
+
+Stagehand v3 can work seamlessly with Playwright, allowing you to use Playwright's `Page` objects directly with Stagehand's AI-powered methods like `act()`, `extract()`, and `observe()`.
+
+## Installation
+
+First, install both Stagehand and Playwright:
+
+```bash
+npm install @browserbasehq/stagehand playwright-core
+```
+
+## Quickstart
+
+### Basic Setup
+
+Connect Playwright to Stagehand's browser instance using Chrome DevTools Protocol (CDP):
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import { chromium } from "playwright-core";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE", // or "LOCAL"
+  model: "openai/gpt-5",
+});
+
+await stagehand.init();
+
+// Connect Playwright to Stagehand's browser
+const browser = await chromium.connectOverCDP({
+  wsEndpoint: stagehand.connectURL(),
+});
+
+const pwContext = browser.contexts()[0];
+const pwPage = pwContext.pages()[0];
+```
+
+### Using Playwright Pages with Stagehand
+
+Once connected, you can use Playwright's `Page` objects with Stagehand's AI-powered methods:
+
+```typescript
+// Navigate using Playwright
+await pwPage.goto("https://example.com");
+
+// Use Stagehand's AI methods with the Playwright page
+await stagehand.act("click the login button", { page: pwPage });
+
+const data = await stagehand.extract(
+  "extract the article title",
+  z.object({ title: z.string() }),
+  { page: pwPage }
+);
+```
+
+## Multi-Page Example
+
+Stagehand works great with multiple Playwright pages:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import { chromium } from "playwright-core";
+import { z } from "zod";
+
+// Initialize Stagehand
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  model: "openai/gpt-5",
+});
+
+await stagehand.init();
+
+// Connect Playwright
+const browser = await chromium.connectOverCDP({
+  wsEndpoint: stagehand.connectURL(),
+});
+
+const pwContext = browser.contexts()[0];
+const pwPage1 = pwContext.pages()[0];
+
+// Create a second page
+const pwPage2 = await pwContext.newPage();
+
+// Navigate both pages
+await pwPage1.goto("https://docs.stagehand.dev/first-steps/introduction");
+await pwPage2.goto("https://docs.stagehand.dev/configuration/observability");
+
+// Extract data from both pages concurrently
+const [page1Data, page2Data] = await Promise.all([
+  stagehand.extract(
+    "extract the names of the four stagehand primitives",
+    z.array(z.string()),
+    { page: pwPage1 }
+  ),
+  stagehand.extract(
+    "extract the list of session dashboard features",
+    z.array(z.string()),
+    { page: pwPage2 }
+  ),
+]);
+
+console.log("Page 1 primitives:", page1Data);
+console.log("Page 2 features:", page2Data);
+```
+
+## Complete Example
+
+Here's a full working example:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import { chromium } from "playwright-core";
+import { z } from "zod";
+
+async function main() {
+  // Initialize Stagehand
+  const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    model: "openai/gpt-5",
+    verbose: 1,
+  });
+
+  await stagehand.init();
+  console.log("Stagehand initialized");
+
+  // Connect Playwright to Stagehand's browser
+  const browser = await chromium.connectOverCDP({
+    wsEndpoint: stagehand.connectURL(),
+  });
+
+  const pwContext = browser.contexts()[0];
+  const pwPage = pwContext.pages()[0];
+
+  // Navigate and interact
+  await pwPage.goto("https://example.com");
+
+  // Use Stagehand's AI methods
+  const actions = await stagehand.observe("find the main heading", {
+    page: pwPage,
+  });
+
+  console.log("Found actions:", actions);
+
+  // Extract data
+  const heading = await stagehand.extract(
+    "extract the main heading text",
+    z.object({ heading: z.string() }),
+    { page: pwPage }
+  );
+
+  console.log("Heading:", heading);
+
+  // Cleanup
+  await stagehand.close();
+}
+
+main();
+```
+
+## Key Points
+
+- **Connect via CDP**: Use `chromium.connectOverCDP()` with `stagehand.connectURL()` as the WebSocket endpoint
+- **Pass the page**: Always pass the Playwright `page` object to Stagehand methods using the `{ page }` option
+- **Multi-page support**: Create multiple pages with `pwContext.newPage()` and pass them to Stagehand methods
+- **Concurrent operations**: Use `Promise.all()` to run multiple Stagehand operations in parallel across different pages
+
+## Environment Variables
+
+When using Browserbase, set your credentials:
+
+```bash
+BROWSERBASE_API_KEY=your_api_key
+```
+
+For OpenAI (or other providers):
+
+```bash
+OPENAI_API_KEY=your_api_key

+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+## Overview
+
+Stagehand v3 can work seamlessly with Puppeteer, allowing you to use Puppeteer's `Page` objects directly with Stagehand's AI-powered methods like `act()`, `extract()`, and `observe()`.
+
+## Installation
+
+First, install both Stagehand and Puppeteer:
+
+```bash
+npm install @browserbasehq/stagehand puppeteer-core
+```
+
+## Quickstart
+
+### Basic Setup
+
+Connect Puppeteer to Stagehand's browser instance:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import puppeteer from "puppeteer-core";
+
+const stagehand = new Stagehand({
+  env: "LOCAL", // or "BROWSERBASE"
+  model: "openai/gpt-5",
+});
+
+await stagehand.init();
+
+// Connect Puppeteer to Stagehand's browser
+const browser = await puppeteer.connect({
+  browserWSEndpoint: stagehand.connectURL(),
+  defaultViewport: null,
+});
+
+const pages = await browser.pages();
+const ppPage = pages[0];
+```
+
+### Using Puppeteer Pages with Stagehand
+
+Once connected, you can use Puppeteer's `Page` objects with Stagehand's AI-powered methods:
+
+```typescript
+// Navigate using Puppeteer
+await ppPage.goto("https://example.com");
+
+// Use Stagehand's AI methods with the Puppeteer page
+await stagehand.act("click the sign in button", { page: ppPage });
+
+const data = await stagehand.extract(
+  "extract the page title",
+  z.object({ title: z.string() }),
+  { page: ppPage }
+);
+```
+
+## Advanced: Multi-Page Usage
+
+Create and manage multiple Puppeteer pages with Stagehand:
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+import puppeteer from "puppeteer-core";
+import { z } from "zod";
+
+async function multiPageExample() {
+  const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    model: "openai/gpt-5",
+  });
+
+  await stagehand.init();
+
+  // Connect Puppeteer
+  const browser = await puppeteer.connect({
+    browserWSEndpoint: stagehand.connectURL(),
+    defaultViewport: null,
+  });
+
+  // Get the first page
+  const pages = await browser.pages();
+  const ppPage1 = pages[0];
+
+  // Create a second page
+  const ppPage2 = await browser.newPage();
+
+  // Navigate both pages
+  await ppPage1.goto("https://example.com");
+  await ppPage2.goto("https://another-site.com");
+
+  // Use Stagehand on different pages
+  await stagehand.act("click the button", { page: ppPage1 });
+
+  const data = await stagehand.extract(
+    "extract the title",
+    z.object({ title: z.string() }),
+    { page: ppPage2 }
+  );
+
+  console.log("Extracted from page 2:", data);
+
+  await stagehand.close();
+}
+```
+
+## Observe + Act Pattern
+
+The recommended pattern for reliable automation:
+
+```typescript
+// Step 1: Observe to find candidate actions
+const actions = await stagehand.observe(
+  "find the submit button",
+  { page: ppPage }
+);
+
+// Step 2: Execute the first action
+if (actions.length > 0) {
+  await stagehand.act(actions[0], { page: ppPage });
+}
+```
+
+This pattern helps avoid DOM changes between observation and action execution.
+
+## Key Points
+
+- **Connect via WebSocket**: Use `puppeteer.connect()` with `stagehand.connectURL()` as the `browserWSEndpoint`
+- **Pass the page**: Always pass the Puppeteer `page` object to Stagehand methods using the `{ page }` option
+- **Disable viewport**: Set `defaultViewport: null` to use Stagehand's viewport settings
+- **Multi-page support**: Create multiple pages with `browser.newPage()` and pass them to Stagehand methods
+
+## Environment Variables
+
+When using Browserbase, set your credentials:
+
+```bash
+BROWSERBASE_API_KEY=your_api_key
+```
+
+For OpenAI (or other providers):
+
+```bash
+OPENAI_API_KEY=your_api_key
+```
+
+## Comparison: Stagehand Native vs Puppeteer
+
+| Feature | Stagehand Native | With Puppeteer |
+|---------|------------------|----------------|
+| **Setup** | Simple - use `stagehand.context.pages()` | Requires `puppeteer.connect()` |
+| **Page Access** | `stagehand.context.pages()[0]` | `await browser.pages()` |
+| **AI Methods** | `stagehand.act("click")` | `stagehand.act("click", { page: ppPage })` |
+| **Best For** | Pure Stagehand workflows | Existing Puppeteer codebases |

+title: Selenium
+description: Use Stagehand with Selenium to operate the same browser in tandem
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+## Overview
+
+Stagehand v3 can work alongside Selenium WebDriver, allowing both tools to operate on the same browser session simultaneously. This enables you to combine Stagehand's AI-powered automation with Selenium's precise element interactions.
+
+<Warning>
+**Browserbase Only**: This integration requires Browserbase. It does not work with `env: "LOCAL"` because Selenium needs a remote WebDriver endpoint.
+</Warning>
+
+## Installation
+
+Install Stagehand, Selenium, and the Browserbase SDK:
+
+```bash
+npm install @browserbasehq/stagehand selenium-webdriver @browserbasehq/sdk
+```
+
+## Quickstart
+
+### Create Shared Session
+
+Use the Browserbase SDK to create a session that both tools can connect to:
+
+```typescript
+import http from "http";
+import { Builder, Key } from "selenium-webdriver";
+import Browserbase from "@browserbasehq/sdk";
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const bb = new Browserbase({
+  apiKey: process.env.BROWSERBASE_API_KEY,
+});
+
+// Create shared session
+const session = await bb.sessions.create({});
+
+console.log("Session created:", session.id);
+```
+
+### Connect Stagehand
+
+Initialize Stagehand with the session ID:
+
+```typescript
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  browserbaseSessionID: session.id,
+  model: "openai/gpt-5",
+  verbose: 2,
+});
+
+await stagehand.init();
+```
+
+### Connect Selenium
+
+Use a custom HTTP agent with the session's signing key:
+
+```typescript
+// Create custom HTTP agent with signing key
+const customHttpAgent = new http.Agent({});
+(customHttpAgent as any).addRequest = (req: any, options: any) => {
+  req.setHeader("x-bb-signing-key", session.signingKey);
+  (http.Agent.prototype as any).addRequest.call(customHttpAgent, req, options);
+};
+
+// Connect Selenium WebDriver
+const driver = new Builder()
+  .forBrowser("chrome")
+  .usingHttpAgent(customHttpAgent)
+  .usingServer(session.seleniumRemoteUrl)
+  .build();
+```
+
+### Use Both Tools Together
+
+Now both Stagehand and Selenium operate on the same browser:
+
+```typescript
+// Navigate with Stagehand
+const page = stagehand.context.pages()[0];
+await page.goto("https://www.google.com");
+
+// Extract page content with Stagehand AI
+const pageContent = await stagehand.extract();
+console.log("Page content:", pageContent);
+
+// Use Selenium for precise element interaction
+const searchBox = await driver.findElement({ name: "q" });
+await searchBox.sendKeys("Browserbase automation");
+await searchBox.sendKeys(Key.RETURN);
+
+// Wait for results
+await driver.sleep(2000);
+
+console.log("Search completed!");
+```
+
+## Key Points
+
+- **Shared Session**: Both tools connect to the same Browserbase session
+- **Signing Key**: Selenium requires the session's `signingKey` in HTTP headers
+- **Remote URL**: Use `session.seleniumRemoteUrl` for Selenium's server endpoint
+- **Concurrent Usage**: Both tools can operate on the browser simultaneously
+- **Cleanup**: Close both Stagehand (`await stagehand.close()`) and Selenium (`await driver.quit()`)

+</Card>
+
+## Add Stagehand to an existing Next.js project
+If you'd like to start from scratch, you can run:
+
+<Tabs>
+<Tab title="npm">
+```bash
+npm create next-app@latest stagehand-nextjs --yes
+cd stagehand-nextjs
+```
+</Tab>
+<Tab title="pnpm">

+cd stagehand-nextjs
+```
+</Tab>
+<Tab title="yarn">
+```bash
+yarn create next-app@latest stagehand-nextjs --yes
+cd stagehand-nextjs
+```
+</Tab>
+</Tabs>
+
+If you'd like to add Stagehand to an existing Next.js project, you can do so by installing the dependencies:
+<Tabs>
+	<Tab title="npm">
+	```bash
+	npm install @browserbasehq/stagehand @browserbasehq/sdk playwright zod
+	```
+	</Tab>
+
+	<Tab title="pnpm">
+	```bash
+	pnpm add @browserbasehq/stagehand @browserbasehq/sdk playwright zod
+	```
+	</Tab>
+
+	<Tab title="yarn">
+	```bash
+	yarn add @browserbasehq/stagehand @browserbasehq/sdk playwright zod
+	```
+	</Tab>
+</Tabs>
+
+### Add environment variables
+Next, let's add the environment variables to a `.env` file.
+```env
+BROWSERBASE_API_KEY=your-browserbase-api-key
+OPENAI_API_KEY=your-openai-api-key
+```
+
+### Write a server action
+Next, let's define our `main` function as a server action in `app/stagehand/main.ts`. This file will have the following three functions:
+
+1. **`main`: Run the main Stagehand script**
+2. **`runStagehand`: Initialize and run the `main` function**
+3. **`startBBSSession`: Start a Browserbase session**
+
+```ts app/stagehand/main.ts
+// 🤘 Welcome to Stagehand!
+// This file is from the [Stagehand docs](https://docs.stagehand.dev/sections/examples/nextjs).
+
+"use server";
+
+import { Stagehand } from "@browserbasehq/stagehand";
+import { z } from "zod";
+import { Browserbase } from "@browserbasehq/sdk";
+
+/**
+ * Run the main Stagehand script
+ */
+async function main(stagehand: Stagehand) {
+  // You can use the `page` instance to write any Playwright code
+  // For more info: https://playwright.dev/docs/pom
+  const page = stagehand.context.activePage();
+
+  // In this example, we'll get the title of the Stagehand quickstart page
+  await page?.goto("https://docs.stagehand.dev/");
+  await stagehand.act("click the quickstart link");
+  const { title } = await stagehand.extract(
+    "extract the main heading of the page",
+    z.object({
+      title: z.string(),
+    }),
+  );
+
+  return title;
+}
+
+/**
+ * Initialize and run the main() function
+ */
+export async function runStagehand(sessionId?: string) {
+  const stagehand = new Stagehand({
+    env: "BROWSERBASE",
+    apiKey: process.env.BROWSERBASE_API_KEY,
+    verbose: 1,
+    logger: console.log,
+    browserbaseSessionID: sessionId,
+    disablePino: true,
+  });
+  await stagehand.init();
+  const result = await main(stagehand);
+  console.log(result);
+  await stagehand.close();
+}
+
+/**
+ * Start a Browserbase session
+ */
+export async function startBBSSession() {
+  const browserbase = new Browserbase();
+  const session = await browserbase.sessions.create({});
+  const debugUrl = await browserbase.sessions.debug(session.id);
+  return {
+    sessionId: session.id,
+    debugUrl: debugUrl.debuggerFullscreenUrl,
+  };
+}
+```
+
+### Create a client component
+Next, let's create a client component that will start a Browserbase session and run the `main` function with the server actions we just defined. We'll first create a Browserbase session and embed the session in an iframe before running the `main` function.
+
+```tsx app/components/stagehandEmbed.tsx
+"use client";
+
+import { useCallback, useState } from "react";
+import { runStagehand, startBBSSession } from "@/app/stagehand/main";
+
+export function StagehandEmbed() {
+  const [sessionId, setSessionId] = useState<string | null>(null);
+  const [debugUrl, setDebugUrl] = useState<string | null>(null);
+
+  const startSession = useCallback(async () => {
+    const { sessionId, debugUrl } = await startBBSSession();
+    setSessionId(sessionId);
+    setDebugUrl(debugUrl);
+    await runStagehand(sessionId);
+  }, []);
+
+  return (
+    <div>
+      {!sessionId && <button onClick={startSession}>Start Session</button>}
+      {sessionId && debugUrl && (
+        <iframe src={debugUrl} className="w-full h-full" />
+      )}
+    </div>
+  );
+}
+```
+
+### Use the `StagehandEmbed` component
+Now, we can use the `StagehandEmbed` component in our app.
+
+```tsx app/page.tsx
+import { StagehandEmbed } from "@/app/components/stagehandEmbed";
+
+export default function Home() {
+	return (
+		<main>
+			<StagehandEmbed />
+		</main>
+	)
+}
+```
+
+### Run the app
+To run the app, you can use the following command:
+
+<Tabs>
+<Tab title="npm">
+```bash
+npm run dev
+```
+</Tab>
+<Tab title="pnpm">
+```bash
+pnpm dev
+```
+</Tab>
+<Tab title="yarn">
+```bash
+yarn dev
+```
+</Tab>
+</Tabs>
+
+### Deploy the app
+To deploy the app, you can use the following commands. First, install the Vercel CLI:
+<Tabs>
+<Tab title="npm">
+```bash
+npm add -g vercel
+```

+title: Migrate Python v2 to v3
+sidebarTitle: Migrate Python v2 to v3
+description: Complete migration guide from Stagehand Python SDK v2 to the new Stainless-based v3 SDK
+icon: 'snake'
+---
+
+This guide helps you migrate from the legacy Stagehand Python SDK to the new Stainless-based SDK with a **Bring Your Own Browser (BYOB)** architecture.
+
+<Note>
+The new Python SDK is a pure API client. You manage the browser yourself using Playwright, Selenium, Puppeteer, or any other browser automation tool. The SDK handles only the AI-powered operations.
+</Note>
+
+## Overview of Changes
+
+<CardGroup cols={2}>
+  <Card title="BYOB Architecture" icon="browser">
+    You bring your own browser driver (Playwright, Selenium, etc.). The SDK is now a pure API client that handles AI-powered operations.
+  </Card>
+  <Card title="Session-Based API" icon="key">
+    All operations require an explicit `session_id`. Start a session, perform operations, and end it when done.
+  </Card>
+  <Card title="Multi-Browser Control" icon="browsers">
+    Scale browsers easily and control multiple browsers at once by passing the session ID for each browser you want to control.
+  </Card>
+  <Card title="Simplified Client" icon="code">
+    Cleaner initialization with dedicated parameters for API keys and configuration.
+  </Card>
+</CardGroup>
+
+### Current Limitations
+
+<Warning>
+The new SDK does **not yet support**:
+- Custom Python LLM client classes (e.g., `model_client_options`)
+- However, we do support custom endpoints like Bedrock or LLM proxies as long as they are OpenAI-API compatible
+</Warning>
+
+---
+
+## Step-by-Step Migration
+
+### 1. Update Imports
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+import asyncio
+import logging
+from stagehand import Stagehand, StagehandConfig, configure_logging
+
+# Configure logging
+configure_logging(
+    level=logging.INFO,
+    remove_logger_name=True,
+    quiet_dependencies=True,
+)
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+import os
+from playwright.sync_api import sync_playwright
+from stagehand import Stagehand
+
+# Note: Custom logging configuration is not yet supported.
+# Use standard Python logging if needed:
+import logging
+logging.basicConfig(level=logging.INFO)
+```
+
+</Tab>
+</Tabs>
+
+---
+
+### 2. Client Initialization
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+config = StagehandConfig(
+    env="BROWSERBASE",
+    api_key=os.getenv("BROWSERBASE_API_KEY"),
+    headless=False,
+    dom_settle_timeout_ms=3000,
+    model_name="google/gemini-2.0-flash",
+    self_heal=True,
+    wait_for_captcha_solves=True,
+    system_prompt="You are a browser automation assistant...",
+    model_client_options={"apiKey": os.getenv("MODEL_API_KEY")},
+    verbose=2,
+)
+
+stagehand = Stagehand(config)
+await stagehand.init()
+page = stagehand.page
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+SDK_VERSION = "3.0.6"
+
+# Create the Stagehand API client
+client = Stagehand(
+    browserbase_api_key=os.environ.get("BROWSERBASE_API_KEY"),
+    model_api_key=os.environ.get("MODEL_API_KEY"),
+)
+
+# Start a session (returns session metadata)
+start_response = client.sessions.start(
+    model_name="google/gemini-2.0-flash",
+    x_language="python",
+    x_sdk_version=SDK_VERSION,
+)
+session_id = start_response.data.session_id
+print(f"Session started: {session_id}")
+
+# Connect Playwright to the Browserbase session
+playwright = sync_playwright().start()
+browser = playwright.chromium.connect_over_cdp(
+    f"wss://connect.browserbase.com?apiKey={os.environ['BROWSERBASE_API_KEY']}&sessionId={session_id}"
+)
+context = browser.contexts[0]
+page = context.pages[0] if context.pages else context.new_page()
+```
+
+</Tab>
+</Tabs>
+
+<Info>
+**Key differences:**
+- Configuration options like `dom_settle_timeout_ms`, `self_heal`, `system_prompt`, and `verbose` are not available in the new SDK
+- `model_name` is specified when starting a session, not in the config
+- You must connect Playwright separately to interact with the page
+</Info>
+
+---
+
+### 3. Navigation
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+await page.goto("https://google.com/")
+```
+
+</Tab>
+<Tab title="New SDK (v3) - Option A: Playwright">
+
+```python
+# Recommended for simple navigation
+page.goto("https://google.com/")
+```
+
+</Tab>
+<Tab title="New SDK (v3) - Option B: Stagehand API">
+
+```python
+# Use this if you need Stagehand to track navigation state
+client.sessions.navigate(
+    id=session_id,
+    url="https://google.com/",
+    frame_id="",  # Empty string for main frame
+    x_language="python",
+    x_sdk_version=SDK_VERSION,
+)
+```
+
+</Tab>
+</Tabs>
+
+---
+
+### 4. Direct Page Interactions (Playwright)
+
+Any direct page manipulation should use Playwright's native API.
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+# Click using Playwright locator (this was already Playwright)
+await page.get_by_role("link", name="About", exact=True).click()
+
+# Keyboard input
+await page.keyboard.press("Enter")
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+# Same Playwright API, but synchronous (or use async Playwright if preferred)
+page.get_by_role("link", name="About", exact=True).click()
+
+# Keyboard input
+page.keyboard.press("Enter")
+```
+
+</Tab>
+</Tabs>
+
+<Note>
+In the old SDK, `page` was a Stagehand-enhanced Playwright page. In the new SDK, `page` is a standard Playwright page. Direct Playwright methods work the same way.
+</Note>
+
+---
+
+### 5. AI-Powered Actions (`act`)
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+await page.act("search for openai")
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+act_response = client.sessions.act(
+    id=session_id,
+    input="search for openai",
+    x_language="python",
+    x_sdk_version=SDK_VERSION,
+)
+print(f"Act completed: {act_response.data.result.message}")
+```
+
+</Tab>
+</Tabs>
+
+#### Acting on an Observed Element
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+observed = await page.observe("find all articles")
+if observed:
+    await page.act(observed[0])
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+observe_response = client.sessions.observe(
+    id=session_id,
+    instruction="find all articles",
+    x_language="python",
+    x_sdk_version=SDK_VERSION,
+)
+results = observe_response.data.result
+
+if results:
+    element = results[0]
+    act_response = client.sessions.act(
+        id=session_id,
+        input=element,  # Pass the observed element directly
+        x_language="python",
+        x_sdk_version=SDK_VERSION,
+    )
+```
+
+</Tab>
+</Tabs>
+
+---
+
+### 6. Observing Elements (`observe`)
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+observed = await page.observe("find all articles")
+if len(observed) > 0:
+    element = observed[0]
+    print(f"Found element: {element}")
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+observe_response = client.sessions.observe(
+    id=session_id,
+    instruction="find all articles",
+    x_language="python",
+    x_sdk_version=SDK_VERSION,
+)
+results = observe_response.data.result
+print(f"Found {len(results)} possible actions")
+
+if results:
+    element = results[0]
+    print(f"Found element: {element.description}")
+```
+
+</Tab>
+</Tabs>
+
+---
+
+### 7. Extracting Data (`extract`)
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+data = await page.extract("extract the first result from the search")
+print(data.model_dump_json())
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+extract_response = client.sessions.extract(
+    id=session_id,
+    instruction="extract the first result from the search",
+    schema={
+        "type": "object",
+        "properties": {
+            "title": {
+                "type": "string",
+                "description": "The title of the first search result"
+            },
+            "url": {
+                "type": "string",
+                "description": "The URL of the first search result"
+            }
+        },
+        "required": ["title"]
+    },
+    x_language="python",
+    x_sdk_version=SDK_VERSION,
+)
+extracted_data = extract_response.data.result
+print(f"Extracted: {extracted_data}")
+```
+
+</Tab>
+</Tabs>
+
+<Warning>
+**Key difference:** The new SDK requires an explicit JSON schema for extraction. This provides better type safety and clearer expectations for the AI model.
+</Warning>
+
+---
+
+### 8. Closing the Session
+
+<Tabs>
+<Tab title="Old SDK (v2)">
+
+```python
+await stagehand.close()
+```
+
+</Tab>
+<Tab title="New SDK (v3)">
+
+```python
+# Clean up Playwright resources
+browser.close()
+playwright.stop()
+
+# End the Stagehand session
+client.sessions.end(
+    id=session_id,
+    x_language="python",
+    x_sdk_version=SDK_VERSION,
+)
+```
+
+</Tab>
+</Tabs>
+
+<Tip>
+**Important:** Always clean up both Playwright and the Stagehand session. Use a `try/finally` block to ensure cleanup happens even on errors.
+</Tip>
+
+---
+
+### 9. Async vs Sync
+
+<Tabs>
+<Tab title="Old SDK (v2) - Async-first">
+
+```python
+async def main():
+    stagehand = Stagehand(config)
+    await stagehand.init()
+    await page.goto("https://example.com")
+    await stagehand.close()
+
+asyncio.run(main())
+```
+
+</Tab>
+<Tab title="New SDK (v3) - Sync-first">
+
+```python
+def main():
+    client = Stagehand(...)
+
+    with sync_playwright() as playwright:
+        # ... setup browser connection
+        page.goto("https://example.com")
+        # ... cleanup
+
+main()
+```
+
+</Tab>
+<Tab title="New SDK (v3) - Async">
+
+```python
+import asyncio
+from playwright.async_api import async_playwright
+
+async def main():
+    client = Stagehand(...)  # Client is sync, but that's OK
+
+    async with async_playwright() as playwright:
+        browser = await playwright.chromium.connect_over_cdp(...)
+        # ... async Playwright operations
+

+sidebarTitle: Migrate TypeScript v2 to v3
+description: Complete migration guide from Stagehand TypeScript SDK v2 to v3
+icon: 'arrow-up-right-dots'
+---
+import { V3Banner } from '/snippets/v3-banner.mdx';
+
+<V3Banner />
+
+
+## Recommended Migration Process
+
+1. **Backup your project**. If you use a version control system, make sure all previous versions are committed.
+2. **Upgrade to Stagehand v3**.
+3. Follow the breaking changes guide below.
+4. Verify your project is working as expected.
+5. Commit your changes.
+
+## Stagehand v3 Package Version
+
+Update your `package.json` to use Stagehand v3:
+
+```bash Bash
+npm install @browserbasehq/stagehand@latest
+```
+
+## Overview of Major Changes
+
+Stagehand v3 introduces significant improvements to the API design and functionality:
+
+- **Removing Playwright Dependency**: Stagehand v3 is now a standalone library that does not depend on Playwright. **You can still use Stagehand with Playwright, check out our [Playwright integration](/v3/integrations/playwright) for more details.**
+- **Simplified Method Signatures**: Cleaner, more intuitive parameter structures.
+- **Unified Model Configuration**: Model configuration is now consolidated into a single `model` parameter.
+- **Automatic iframe & Shadow DOM Support**: No more manual flags required.
+- **Improved Type Safety**: Better TypeScript inference and type checking.
+- **Enhanced Multi-Page Support**: New Context API for managing multiple pages.
+- **Streamlined Timeouts**: Consistent timeout naming across all methods.
+- **Auto-caching**: Stagehand v3 now automatically caches actions and agent steps using the [file system cache](/best-practices/caching).
+- **Agent Improvements**: Renamed parameters (`instructions` → `systemPrompt`), unified model configuration, and new `executionModel` option for cost optimization.
+
+
+## Breaking Changes
+
+### Stagehand Initialization
+
+#### Model Configuration Consolidation
+
+The `modelName` and `modelClientOptions` parameters have been unified into a single `model` parameter.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  apiKey: process.env.BROWSERBASE_API_KEY,
+  modelName: "openai/gpt-5",
+  modelClientOptions: {
+    apiKey: process.env.OPENAI_API_KEY
+    baseURL: "https://custom-proxy.com/v1"
+  }
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+import { Stagehand } from "@browserbasehq/stagehand";
+
+// Option 1: String format (recommended for simplicity, auto-loads model API key from env)
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  apiKey: process.env.BROWSERBASE_API_KEY,
+  model: "openai/gpt-5"
+});
+
+// Option 2: Object format (for advanced configuration)
+const stagehand = new Stagehand({
+  env: "BROWSERBASE",
+  apiKey: process.env.BROWSERBASE_API_KEY,
+  model: {
+    modelName: "gpt-5",
+    apiKey: process.env.OPENAI_API_KEY,
+    baseURL: "https://custom-proxy.com/v1"
+  }
+});
+```
+
+#### DOM Settle Timeout Rename
+
+The `domSettleTimeoutMs` parameter has been renamed to `domSettleTimeout` for consistency.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  domSettleTimeoutMs: 5000
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  domSettleTimeout: 5000
+});
+```
+
+#### Changes to return value of `stagehand.init()`
+
+The `init()` used to return `debugUrl`, `sessionUrl` and `sessionId`
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const result = await stagehand.init();
+console.log(result);
+```
+In `v2`, the returned object contains:
+```
+{
+  debugUrl: 'https://www.browserbase.com/devtools/inspector.html?wss=connect.browserbase.com/debug/f8a21b4a-6fa1-4ab9-9007-fbfe61dc14f0/devtools/page/5474B0E0510C5B6E629BEB06E799CD70?debug=true',
+  sessionUrl: 'https://www.browserbase.com/sessions/f8a21b4a-6fa1-4ab9-9007-fbfe61dc14f0',
+  sessionId: 'f8a21b4a-6fa1-4ab9-9007-fbfe61dc14f0'
+}
+```
+In `v3` the return value is `Promise<void>`. The `sessionId`, `sessionUrl`, and `debugUrl` are now directly accessible via the stagehand object:
+```typescript Stagehand v3 icon="/images/typescript.svg"
+console.log("debugUrl: ", stagehand.browserbaseDebugURL)
+console.log("sessionUrl: ", stagehand.browserbaseSessionURL)
+console.log("sessionId: ", stagehand.browserbaseSessionID)
+```
+Example output:
+```
+debugUrl: 'https://www.browserbase.com/devtools/inspector.html?wss=connect.browserbase.com/debug/f8a21b4a-6fa1-4ab9-9007-fbfe61dc14f0/devtools/page/5474B0E0510C5B6E629BEB06E799CD70?debug=true',
+sessionUrl: 'https://www.browserbase.com/sessions/f8a21b4a-6fa1-4ab9-9007-fbfe61dc14f0',
+sessionId: 'f8a21b4a-6fa1-4ab9-9007-fbfe61dc14f0'
+```
+
+#### Caching Changes
+
+The `enableCaching` boolean has been replaced with a `cacheDir` string for more flexible cache management.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  enableCaching: true
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const stagehand = new Stagehand({
+  env: "LOCAL",
+  cacheDir: "./stagehand-cache"  // Specify cache directory
+});
+```
+
+#### Page Access Changes
+
+Direct page access has changed to use the Context API.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+
+// Direct page access
+const page = stagehand.page;
+await page.goto("https://example.com");
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+
+// Access via context
+const page = stagehand.context.pages()[0];
+await page.goto("https://example.com");
+
+// Or `await` the active page
+const page = stagehand.context.awaitActivePage();
+await page.goto("https://example.com");
+```
+
+### Context and Multi-Page Management
+
+#### New Context API
+
+v3 introduces a structured Context API for managing multiple pages.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+
+// Limited multi-page support
+const page = stagehand.page;
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+
+// Access all pages
+const pages = stagehand.context.pages();
+const mainPage = pages[0];
+
+// Create new page
+const newPage = await stagehand.context.newPage();
+
+// Set active page
+stagehand.context.setActivePage(newPage);
+
+// implicitly takes action on newPage
+await stagehand.act("click button");
+```
+
+### act() Method Changes
+
+#### Method Signature Simplification
+
+The `action` parameter has been removed from `ActOptions`. Now you only pass the instruction as a string.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+await page.act({
+  action: "click the login button",
+  modelName: "openai/gpt-5-mini",
+  variables: { username: "john" },
+  timeoutMs: 10000,
+  domSettleTimeoutMs: 5000,
+  iframes: true
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// Clean, simple string instruction
+await stagehand.act("click the login button");
+
+// With options
+await stagehand.act("click the login button", {
+  model: "openai/gpt-5-mini",
+  variables: { username: "john" },
+  timeout: 10000,
+  page: page  // Optional: specify which page
+});
+```
+
+<Note>
+**Method Location Change**: In v3, `act()` is called on the `stagehand` instance, not the `page` object.
+</Note>
+
+#### Model Configuration in act()
+
+Model configuration follows the same pattern as initialization.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+await page.act({
+  action: "fill the form",
+  modelName: "anthropic/claude-sonnet-4-5",
+  modelClientOptions: {
+    apiKey: process.env.ANTHROPIC_API_KEY
+  }
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// String format
+await stagehand.act("fill the form", {
+  model: "anthropic/claude-sonnet-4-5"
+});
+
+// Object format
+await stagehand.act("fill the form", {
+  model: {
+    modelName: "anthropic/claude-sonnet-4-5",
+    apiKey: process.env.ANTHROPIC_API_KEY
+  }
+});
+```
+
+#### Timeout Parameter Rename
+
+`timeoutMs` has been renamed to `timeout`.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+await page.act({
+  action: "click button",
+  timeoutMs: 15000
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+await stagehand.act("click button", {
+  timeout: 15000
+});
+```
+
+#### Automatic iframe Support
+
+The `iframes` flag has been removed. iframe support is now automatic.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+await page.act({
+  action: "click button inside iframe",
+  iframes: true  // Required to interact with iframes
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// Automatic iframe support - no flag needed
+await stagehand.act("click button inside iframe");
+```
+
+<Note>
+**Automatic Support**: Stagehand v3 automatically handles iframe and Shadow DOM interactions without requiring explicit flags.
+</Note>
+
+#### Result Structure Changes
+
+The `ActResult` structure has been enhanced with more detailed information.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const result = await page.act("click the button");
+console.log(result.action);  // Single action string
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const result = await stagehand.act("click the button");
+console.log(result.actionDescription);  // Overall description
+console.log(result.actions);  // Array of action details
+
+// ActResult structure:
+// {
+//   success: boolean;
+//   message: string;
+//   actionDescription: string;
+//   actions: Array<{
+//     selector: string;
+//     description: string;
+//     method?: string;
+//     arguments?: string[];
+//   }>;
+// }
+```
+
+### extract() Method Changes
+
+#### Method Location and Signature
+
+`extract()` has moved from the page object to the stagehand instance, with a cleaner parameter structure.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+import { z } from "zod";
+
+const result = await page.extract({
+  instruction: "extract product details",
+  schema: z.object({
+    name: z.string(),
+    price: z.number()
+  }),
+  modelName: "openai/gpt-5",
+  domSettleTimeoutMs: 5000,
+  selector: "xpath=/html/body/div",
+  iframes: true
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+import { z } from "zod";
+
+// Cleaner parameter structure
+const result = await stagehand.extract(
+  "extract product details",
+  z.object({
+    name: z.string(),
+    price: z.number()
+  }),
+  {
+    model: "openai/gpt-5",
+    selector: ".container", // NEW: CSS selector support
+    timeout: 10000,
+    page: page  // Optional: specify which page
+  }
+);
+```
+
+<Note>
+**Parameter Order**: In v3, `instruction` and `schema` are separate positional parameters, with `options` as an optional third parameter.
+</Note>
+
+#### Extract Without Schema
+
+Schema-less extraction also has a simpler interface.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+// String instruction
+const result = await page.extract("get the page title");
+// Returns: { extraction: "Page Title" }
+
+// Raw page content
+const content = await page.extract();
+// Returns: { page_text: "..." }
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// String instruction
+const result = await stagehand.extract("get the page title");
+// Returns: { extraction: "Page Title" }
+
+// Raw page content
+const content = await stagehand.extract();
+// Returns: { pageText: "..." }
+```
+
+#### Model Configuration in extract()
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const data = await page.extract({
+  instruction: "extract data",
+  schema: DataSchema,
+  modelName: "anthropic/claude-sonnet-4-5",
+  modelClientOptions: {
+    apiKey: process.env.ANTHROPIC_API_KEY
+  }
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const data = await stagehand.extract(
+  "extract data",
+  DataSchema,
+  {
+    model: "anthropic/claude-sonnet-4-5"
+  }
+);
+```
+
+#### Automatic iframe Support
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const data = await page.extract({
+  instruction: "extract data from iframe",
+  schema: DataSchema,
+  iframes: true  // Required for iframe content
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// Automatic iframe support
+const data = await stagehand.extract(
+  "extract data from iframe",
+  DataSchema
+);
+```
+
+#### Array Schema Changes
+
+Array extraction now has a more ergonomic syntax.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+import { z } from "zod";
+
+// Had to wrap array in object
+const ApartmentListingsSchema = z.object({
+  apartments: z.array(z.object({
+    address: z.string(),
+    price: z.string(),
+    bedrooms: z.number()
+  }))
+});
+
+const result = await page.extract({
+  instruction: "extract all apartment listings",
+  schema: ApartmentListingsSchema
+});
+
+// Access via: result.apartments
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+import { z } from "zod";
+
+// Can use array schema directly
+const ApartmentListingsSchema = z.array(
+  z.object({
+    address: z.string(),
+    price: z.string(),
+    bedrooms: z.number()
+  })
+);
+
+const result = await stagehand.extract(
+  "extract all apartment listings",
+  ApartmentListingsSchema
+);
+
+// Result is directly the array
+console.log(result[0].address);
+```
+
+### observe() Method Changes
+
+#### Method Signature Updates
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const results = await page.observe({
+  instruction: "find all buttons",
+  modelName: "openai/gpt-5",
+  domSettleTimeoutMs: 5000,
+  drawOverlay: true,
+  iframes: true
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const results = await stagehand.observe("find all buttons", {
+  model: "openai/gpt-5",
+  timeout: 10000,
+  selector: ".container",  // NEW: scope observation to selector
+  page: page  // Optional: specify which page
+});
+```
+
+<Note>
+**Method Location Change**: Like `act()` and `extract()`, `observe()` is now called on the `stagehand` instance.
+</Note>
+
+#### Draw Overlay Removed
+
+The `drawOverlay` option has been removed in v3.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const results = await page.observe({
+  instruction: "find buttons",
+  drawOverlay: true  // Visual debugging
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// drawOverlay is no longer available
+const results = await stagehand.observe("find buttons");
+```
+
+#### Automatic iframe Support
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const results = await page.observe({
+  instruction: "find elements in iframe",
+  iframes: true
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// Automatic iframe support
+const results = await stagehand.observe("find elements in iframe");
+```
+
+#### Observe with act() Integration
+
+The observe → act workflow remains similar but with updated method signatures.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const [action] = await page.observe("find the login button");
+await page.act(action);
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const [action] = await stagehand.observe("find the login button");
+await stagehand.act(action);
+```
+
+### agent() Method Changes
+
+#### Agent Configuration Updates
+
+The agent configuration has been significantly restructured in v3 with renamed parameters and new capabilities.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const agent = stagehand.agent({
+  provider: "google",
+  model: "gemini-2.5-computer-use-preview-10-2025",
+  instructions: "You are a helpful assistant that can navigate websites.",
+  options: {
+    apiKey: process.env.GEMINI_API_KEY
+  },
+  integrations: ["https://mcp-server.example.com"],
+  tools: customTools
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const agent = stagehand.agent({
+  model: "google/gemini-2.5-computer-use-preview-10-2025",  // Provider now in model string
+  systemPrompt: "You are a helpful assistant that can navigate websites.",  // Renamed from 'instructions'
+  mode: "cua",  // Computer Use Agent mode
+  integrations: ["https://mcp-server.example.com"],
+  tools: customTools
+});
+```
+
+<Note>
+**Key Changes**:
+- `provider` removed - now part of the model string (e.g., `"anthropic/claude-sonnet-4-5"`)
+- `instructions` renamed to `systemPrompt`
+- `options` removed - use model object format for advanced configuration
+- `executionModel` added - specify a different model for tool execution
+- `cua` flag added - enable/disable Computer Use Agent mode
+</Note>
+
+#### Model Configuration in agent()
+
+Model configuration follows the same unified pattern as other methods.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const agent = stagehand.agent({
+  provider: "google",
+  model: "gemini-2.5-computer-use-preview-10-2025",
+  options: {
+    apiKey: process.env.GEMINI_API_KEY,
+    baseURL: "https://custom-proxy.com/v1"
+  }
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+// String format (recommended)
+const agent = stagehand.agent({
+  model: "google/gemini-2.5-computer-use-preview-10-2025"
+});
+
+// Object format for advanced configuration
+const agent = stagehand.agent({
+  model: {
+    modelName: "gemini-2.5-computer-use-preview-10-2025",
+    apiKey: process.env.GEMINI_API_KEY,
+    baseURL: "https://custom-proxy.com/v1"
+  }
+});
+```
+
+#### Execute Method Changes
+
+The `execute()` method has been simplified with some options removed and new ones added.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const result = await agent.execute({
+  instruction: "Search for products",
+  maxSteps: 20,
+  autoScreenshot: true,
+  waitBetweenActions: 1000,
+  context: "Focus on electronics category"
+});
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const result = await agent.execute({
+  instruction: "Search for products",
+  maxSteps: 20,
+  page: page,  // NEW: specify which page to operate on
+  highlightCursor: true  // NEW: visual cursor for debugging
+});
+```
+
+<Warning>
+**Removed Options**:
+- `autoScreenshot` - no longer available
+- `waitBetweenActions` - no longer available
+- `context` - use the `systemPrompt` in agent config instead
+</Warning>
+
+#### Execution Model Configuration
+
+v3 introduces a new `executionModel` option to use a different (often faster/cheaper) model for tool execution.
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5",  // Main reasoning model
+  executionModel: "anthropic/claude-haiku-4-5"  // Faster model for tool execution (act, extract, observe)
+});
+
+// The agent will use claude-sonnet-4-5 for high-level reasoning
+// but claude-haiku-4-5 for executing individual actions
+const result = await agent.execute("Complete the checkout process");
+```
+
+#### Agent with Multi-Page Support
+
+v3 agents can now specify which page to operate on.
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const page1 = stagehand.context.pages()[0]
+const page2 = await stagehand.context.newPage();
+
+const agent = stagehand.agent({
+  model: "google/gemini-2.5-computer-use-preview-10-2025"
+});
+
+// Execute on specific page
+await page2.goto("https://example.com/dashboard");
+const result = await agent.execute({
+  instruction: "Export the data table",
+  page: page2  // Operate on page2 instead of default page
+});
+```
+
+### History and Metrics
+
+#### History API
+
+History is now async and returns a promise.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const history = stagehand.history;
+```
+
+```typescript Stagehand v3 icon="/images/typescript.svg"
+const history = await stagehand.history;
+```
+
+#### Metrics API
+
+Metrics is now async and returns a promise.
+
+```typescript Stagehand v2 icon="/images/typescript.svg"
+const metrics = stagehand.metrics;

+
+## Troubleshooting
+
+### Error: Cannot find property 'page' on Stagehand instance
+
+**Problem**: Direct `stagehand.page` is not supported in Stagehand v3.
+
+**Solution**: Use the Context API or `await` the active page:
+
+```typescript
+// Use context API (recommended)
+const page = stagehand.context.pages()[0];
+
+// Or grab the active page
+const page = await stagehand.context.awaitActivePage();
+```
+
+### Error: act() method not found on page
+
+**Problem**: v3 moved `act()`, `extract()`, and `observe()` to the stagehand instance.
+
+**Solution**: Call these methods on the stagehand instance:
+
+```typescript
+// v2 ❌
+await page.act("click button");
+
+// v3 ✅
+await stagehand.act("click button");
+```
+
+### TypeScript: Model configuration type errors
+
+**Problem**: TypeScript errors with model configuration.
+
+**Solution**: Use the proper format:
+
+```typescript
+// String format
+model: "openai/gpt-5"
+
+// Object format
+model: {
+  modelName: "openai/gpt-5",
+  apiKey: process.env.OPENAI_API_KEY
+}
+```
+
+### Agent configuration errors
+
+**Problem**: Using old `provider` and `instructions` parameters.
+
+**Solution**: Update to v3 format:
+
+```typescript
+// v2 ❌
+const agent = stagehand.agent({
+  provider: "anthropic",
+  model: "claude-sonnet-4-5",
+  instructions: "You are a helpful assistant that..."
+});
+
+// v3 ✅
+const agent = stagehand.agent({
+  model: "anthropic/claude-sonnet-4-5",
+  systemPrompt: "You are a helpful assistant that..."
+});
+```
+
+### Agent execute options not recognized
+
+**Problem**: Using removed options like `autoScreenshot`, `waitBetweenActions`, or `context`.
+
+**Solution**: Remove these options and use v3 alternatives:
+
+```typescript
+// v2 ❌
+await agent.execute({
+  instruction: "task",
+  autoScreenshot: true,
+  waitBetweenActions: 1000,
+  context: "additional context"
+});
+
+// v3 ✅
+const agent = stagehand.agent({
+  model: "google/gemini-2.5-computer-use-preview-10-2025",
+  systemPrompt: "Your context here."  // Move context to systemPrompt
+});
+
+await agent.execute({
+  instruction: "task",
+  highlightCursor: true  // Use new option for visual feedback
+});
+```
+
+## Best Practices for v3
+
+1. **Use the string model format** for simplicity: `model: "openai/gpt-5"`
+2. **Leverage automatic iframe support** - remove all `iframes` flags
+3. **Use the Context API** for multi-page scenarios
+4. **Monitor metrics** to track token usage and optimize costs
+5. **Use history** for debugging and understanding automation flow
+6. **Set appropriate timeouts** based on your use case
+7. **Specify cache directory** to improve performance for repeated actions
+8. **Use executionModel for agents** - configure a faster/cheaper model for tool execution while keeping a powerful model for reasoning (e.g., `model: "anthropic/claude-sonnet-4-5"`, `executionModel: "google/gemini-2.0-flash"`)

+### Parameters
+
+<ParamField path="instruction | action" type="string | Action" required>
+  - **Instruction**: Natural language description of the action to perform. Use `%variableName%` syntax to reference variables.
+  - **Action**: A deterministic action to perform: 
+  <Expandable title="Action">
+    <ParamField path="selector" type="string" required>
+      The selector (XPath, CSS selector, etc.) used to target the element
+    </ParamField>
+    <ParamField path="description" type="string" required>

+
+  If not specified, defaults to the current "active" page in your Stagehand instance.
+</ParamField>
+
+<ParamField path="serverCache" type="boolean" optional>
+  Override the instance-level `serverCache` setting for this request. When `true`, enables server-side caching. When `false`, disables it.
+
+  <Note>Only applies when `env` is `"BROWSERBASE"`. Has no effect in local environments.</Note>
+
+  Defaults to the value set on the Stagehand constructor (which itself defaults to `true`).
+</ParamField>
+
+### Returns `Promise<ActResult>`
+
+<ResponseField name="success" type="boolean" required>
+  Whether the action completed successfully
+</ResponseField>
+
+<ResponseField name="message" type="string" required>
+  Human-readable message describing the result
+</ResponseField>
+

+    </ResponseField>
+    <ResponseField name="arguments" type="string[]">
+      Arguments passed to the method
+    </ResponseField>
+  </Expandable>
+</ResponseField>
+
+<ResponseField name="cacheStatus" type='"HIT" | "MISS"' optional>
+  Indicates whether the result was served from the server-side cache. Only present when running with `env: "BROWSERBASE"` and server-side caching is enabled.
+
+  - **`"HIT"`** - Result was served from cache; no LLM tokens were consumed
+  - **`"MISS"`** - Result was computed fresh and cached for future calls
+</ResponseField>
+
+**Example Response:**
+```json

+  **Array of:** MCP server URLs (strings) or connected Client objects
+</ParamField>
+
+<ParamField path="tools" type="ToolSet" optional>
+  Custom tool definitions to extend agent capabilities using the AI SDK ToolSet format.
+</ParamField>
+
+<ParamField path="stream" type="boolean" optional>
+  Enable streaming mode for the agent. When `true`, `execute()` returns `AgentStreamResult` with `textStream` for incremental output. When `false` (default), `execute()` returns `AgentResult` after completion.
+  
+  **Default:** `false`
+  
+  <Warning>**Non-CUA agents only.** Requires `experimental: true`. Not available when `mode: "cua"`.</Warning>
+</ParamField>
+
+<ParamField path="mode" type='"dom" | "hybrid" | "cua"' optional>
+  Tool mode for the agent. Determines which set of tools are available to the agent.
+  
+  **Modes:**
+  - `"dom"`: Uses DOM based tools (`act`, `fillForm`) for structured page interactions. Works with any model.
+  - `"hybrid"`: Uses both DOM-based and coordinate-based tools (`act`, `click`, `type`, `dragAndDrop`, `clickAndHold`, `fillForm`) for visual/screenshot-based interactions. Requires models with reliable coordinate-based action capabilities.
+  - `"cua"`: Uses Computer Use Agent (CUA) providers like Anthropic Claude, Google Gemini, or OpenAI for screenshot-based automation. This is the preferred way to enable CUA mode (replaces the deprecated `cua: true` option).
+
+  **Default:** When unspecified, the mode is auto-resolved based on the model — `"hybrid"` for hybrid-capable models (Claude, GPT-5.4, Gemini 3) and `"dom"` for everything else.
+
+  <Warning>
+  **Hybrid Mode Model Requirements:** Only use hybrid mode with models that can reliably perform coordinate-based actions:
+  - **Anthropic:** any Claude model (e.g. `anthropic/claude-sonnet-4-20250514`, `anthropic/claude-sonnet-4-5-20250929`, `anthropic/claude-haiku-4-5-20251001`)
+  - **OpenAI:** `openai/gpt-5.4`, `openai/gpt-5.4-mini`
+  - **Google:** `google/gemini-3-flash-preview`, `google/gemini-3.1-flash-lite-preview`, `google/gemini-3.1-pro-preview`
+
+  Requires `experimental: true` in Stagehand constructor.
+  </Warning>

+</Card>
+</CardGroup>
+
+## Overview
+
+The `clipboard` object reads from and writes to the browser clipboard for the active page or an explicit page. Use it to seed text before pasting into focused fields, inspect copied text, or perform keyboard-driven copy, cut, and paste actions.
+
+Access the clipboard through your Stagehand context:
+
+```typescript
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+const clipboard = stagehand.context.clipboard;
+```
+
+By default, clipboard operations target `context.activePage()`. Pass a `page` option when you need to use a specific tab.
+
+<Note>
+Browser clipboard access requires page focus. When you pass a `page` argument, Stagehand uses that page for clipboard access, brings it to the front when possible, and makes it the context's active page before running the operation.
+</Note>
+
+## Methods
+
+### writeText()
+
+Write text to the browser clipboard.
+
+```typescript
+await context.clipboard.writeText(text: string, options?: ClipboardOptions): Promise<void>
+```
+
+<ParamField path="text" type="string" required>
+  The text to write to the clipboard.
+</ParamField>

+      Keyboard shortcut to use for paste.
+
+      **Default:** `"ControlOrMeta+V"`
+    </ParamField>

+
+## Behavior
+
+- `readText()`, `writeText()`, and `clear()` grant browser clipboard permissions for the page origin when possible.
+- `paste()`, `copy()`, and `cut()` use keyboard shortcuts and depend on focus and selection state in the target page.

+
+## Overview
+
+The `context` object manages the browser context, which is a container for multiple pages (tabs). It provides methods for creating new pages, accessing existing pages, and managing which page is currently active.
+
+Access the context through your Stagehand instance:
+
+```typescript
+const stagehand = new Stagehand({ env: "BROWSERBASE" });
+await stagehand.init();
+const context = stagehand.context;
+```
+
+## Methods
+
+### newPage()
+
+Create a new page (tab) in the browser.
+
+```typescript
+await context.newPage(url?: string): Promise<Page>
+```
+
+<ParamField path="url" type="string" optional>
+  The URL to navigate to in the new page.
+
+  **Default:** `"about:blank"`
+</ParamField>
+
+**Returns:** `Promise<Page>` - The newly created page object.
+
+The new page is automatically set as the active page.
+
+### pages()
+
+Get all open pages in the browser context.
+
+```typescript
+context.pages(): Page[]
+```
+
+**Returns:** `Page[]` - Array of all open pages, ordered from oldest to newest.
+
+### activePage()
+
+Get the currently active page.
+
+```typescript
+context.activePage(): Page | undefined
+```
+
+**Returns:** `Page | undefined` - The most recently used page, or `undefined` if no pages exist.
+
+The active page is determined by:
+1. Most recently interacted with page
+2. Most recently created page if no interaction history
+3. `undefined` if all pages have been closed
+
+### setActivePage()
+
+Set a specific page as the active page.
+
+```typescript
+context.setActivePage(page: Page): void
+```
+
+<ParamField path="page" type="Page" required>
+  The page to set as active. Must be a page that exists in this context.
+</ParamField>
+
+This method:
+- Marks the page as most recently used
+- Brings the tab to the foreground (in headed mode)
+- Makes it the default page for subsequent operations
+
+### addInitScript()
+
+Inject JavaScript that runs before any page scripts on every navigation.
+
+```typescript
+await context.addInitScript<Arg>(
+  script: string | { path?: string; content?: string } | ((arg: Arg) => unknown),
+  arg?: Arg,
+): Promise<void>
+```
+
+<ParamField
+  path="script"
+  type="string | { path?: string; content?: string } | (arg: Arg) => unknown"
+  required
+>
+  Provide the script to inject. Pass raw source code, reference a file on disk,
+  or supply a function that Stagehand serializes before sending to the browser.
+</ParamField>
+
+<ParamField path="arg" type="Arg" optional>
+  Extra data that is JSON-serialized and passed to your function. Only supported
+  when `script` is a function.
+</ParamField>
+
+This method:
+- Runs at document start, and installs the script on all currently open pages and replays it on every
+  navigation of those pages
+- Automatically applies the same script to any pages created after calling
+  `context.addInitScript()`
+- Allows referencing preload files via `{ path: "./preloads/dom-hooks.js" }`,
+  mirroring Playwright's `sourceURL` behavior for readable stack traces
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+const context = stagehand.context;
+
+// Add some JavaScript to automatically accept alert dialogs
+await context.addInitScript(() => {
+   window.alert = () => {};
+   window.confirm = () => true;
+   window.prompt = () => '';
+ });
+```
+
+### setExtraHTTPHeaders()
+
+Set HTTP headers that will be included in every request made by all pages in the browser context.
+
+```typescript
+await context.setExtraHTTPHeaders(headers: Record<string, string>): Promise<void>
+```
+
+<ParamField path="headers" type="Record<string, string>" required>
+  A plain object of header name–value pairs. All values must be strings.
+</ParamField>
+
+This method:
+- Applies the headers to all existing pages in the context immediately
+- Automatically applies the same headers to any pages created after calling `setExtraHTTPHeaders()`
+- Calling it again replaces all previously set extra headers (it does not merge)
+- To clear all extra headers, pass an empty object: `await context.setExtraHTTPHeaders({})`
+
+<Note>
+Headers set via `context.setExtraHTTPHeaders()` are context-wide. They apply to every network request from every page in the context, including navigation requests, XHR/fetch calls, and subresource loads.
+</Note>
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+const context = stagehand.context;
+
+// Set custom headers for all requests
+await context.setExtraHTTPHeaders({
+  "X-Custom-Token": "my-secret-token",
+  "Accept-Language": "en-US",
+});
+
+// All subsequent requests from any page in this context
+// will include these headers
+const page = await context.newPage("https://example.com");
+```
+
+### setDomainPolicy()
+
+Set a context-wide network domain policy that allows or blocks HTTP(S) requests by hostname.
+
+```typescript
+await context.setDomainPolicy(policy: DomainPolicy | null): Promise<void>
+```
+
+<ParamField path="policy" type="DomainPolicy | null" required>
+  A domain policy with `allowedDomains`, `blockedDomains`, or both.
+
+  <Expandable title="DomainPolicy">
+    <ParamField path="allowedDomains" type="string[]" optional>
+      Domain-only allow patterns. When provided, HTTP(S) requests to non-matching domains are blocked.
+    </ParamField>
+
+    <ParamField path="blockedDomains" type="string[]" optional>
+      Domain-only block patterns. Matching HTTP(S) requests are blocked.
+    </ParamField>
+  </Expandable>
+</ParamField>
+
+Domain policy applies to HTTP and HTTPS requests across existing and future pages, attached child targets, iframes, and subresource loads. It is not limited to top-level page navigations. Non-HTTP(S) URLs such as `data:` and `file:` are not blocked by this policy.
+
+<Note>
+For newly opened targets, such as popups opened via `window.open()`, domain blocking can be race-sensitive. If Stagehand cannot guarantee that a disallowed target was intercepted in time, it closes that target.
+</Note>
+
+Calling `setDomainPolicy()` replaces the previous policy. To clear the policy, pass `null`, `{}`, or empty arrays:
+
+```typescript
+await context.setDomainPolicy(null);
+```
+
+Domain patterns must be domain-only values:
+- Use `"example.com"` for an exact hostname match
+- Use `"*.example.com"` to match subdomains such as `"app.example.com"` and `"deep.app.example.com"`
+- `"*.example.com"` does not match the apex domain `"example.com"`; include both patterns if you need both
+- Do not include a scheme, path, port, query string, or fragment
+- Matching is case-insensitive, and duplicate normalized patterns are ignored
+
+<Note>
+When both `blockedDomains` and `allowedDomains` are provided, `blockedDomains` takes precedence. Blocked requests fail with Chrome's `BlockedByClient` network error.
+</Note>
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+const context = stagehand.context;
+
+await context.setDomainPolicy({
+  allowedDomains: ["example.com", "*.example.com"],
+  blockedDomains: ["ads.example.com", "*.tracking.example.com"],
+});
+
+const page = await context.newPage("https://example.com");
+```
+
+### getDomainPolicy()
+
+Get the currently configured context-wide domain policy.
+
+```typescript
+context.getDomainPolicy(): DomainPolicy | null
+```
+
+**Returns:** `DomainPolicy | null` - The active domain policy, or `null` when no policy is configured.
+
+### cookies()
+
+Retrieve browser cookies, optionally filtered by URL(s).
+
+```typescript
+await context.cookies(urls?: string | string[]): Promise<Cookie[]>
+```
+
+<ParamField path="urls" type="string | string[]" optional>
+  A single URL or array of URLs to filter cookies by. When provided, only cookies that match the domain, path, and secure requirements of the given URLs are returned.
+
+  **Default:** Returns all cookies when omitted.
+</ParamField>
+
+**Returns:** `Promise<Cookie[]>` - Array of cookie objects.
+
+```typescript
+// Get all cookies
+const allCookies = await context.cookies();
+
+// Get cookies for a specific URL
+const siteCookies = await context.cookies("https://example.com");
+
+// Get cookies for multiple URLs
+const cookies = await context.cookies([
+  "https://example.com",
+  "https://api.example.com",
+]);
+```
+
+### addCookies()
+
+Set one or more cookies in the browser context.
+
+```typescript
+await context.addCookies(cookies: CookieParam[]): Promise<void>
+```
+
+<ParamField path="cookies" type="CookieParam[]" required>
+  Array of cookie parameters to set. Each cookie must provide either `url` or both `domain` and `path` — providing both `url` and `domain` (or `url` and `path`) will throw a validation error.
+</ParamField>
+
+<Note>
+Cookies set via `context.addCookies()` are shared across all pages in the context, scoped by domain and path.
+</Note>
+
+```typescript
+// Set a cookie using a URL
+await context.addCookies([
+  {
+    name: "session",
+    value: "abc123",
+    url: "https://example.com",
+  },
+]);
+
+// Set a cookie using domain and path
+await context.addCookies([
+  {
+    name: "token",
+    value: "xyz789",
+    domain: ".example.com",
+    path: "/",
+    secure: true,
+    httpOnly: true,
+    sameSite: "Strict",
+  },
+]);
+```
+
+<Warning>
+Setting `sameSite: "None"` requires `secure: true`. Stagehand will throw a validation error if this requirement is not met.
+</Warning>
+
+### clearCookies()
+
+Clear cookies from the browser context. Can clear all cookies or selectively filter by name, domain, or path.
+
+```typescript
+await context.clearCookies(options?: ClearCookieOptions): Promise<void>
+```
+
+<ParamField path="options" type="ClearCookieOptions" optional>
+  Filter options to selectively clear cookies. When omitted, all cookies are cleared.
+
+  <Expandable title="ClearCookieOptions">
+    <ParamField path="name" type="string | RegExp" optional>
+      Match cookies by name. Supports exact string match or RegExp.
+    </ParamField>
+
+    <ParamField path="domain" type="string | RegExp" optional>
+      Match cookies by domain. Supports exact string match or RegExp.
+    </ParamField>
+
+    <ParamField path="path" type="string | RegExp" optional>
+      Match cookies by path. Supports exact string match or RegExp.
+    </ParamField>
+  </Expandable>
+</ParamField>
+
+```typescript
+// Clear all cookies
+await context.clearCookies();
+
+// Clear cookies by exact name
+await context.clearCookies({ name: "session" });
+
+// Clear cookies by domain pattern
+await context.clearCookies({ domain: /\.example\.com$/ });
+
+// Combine filters (a cookie must match ALL provided filters to be cleared)
+await context.clearCookies({
+  name: "token",
+  domain: ".example.com",
+});
+```
+
+### close()
+
+Close the browser context and all associated pages.
+
+```typescript
+await context.close(): Promise<void>
+```
+
+This method:
+- Closes the CDP connection
+- Cleans up all pages
+- Clears all internal mappings
+
+**Note:** This is typically called internally by `stagehand.close()`. You usually don't need to call this directly.
+
+## Properties
+
+### clipboard
+
+Access the browser clipboard API for the active page or a specific page.
+
+```typescript
+context.clipboard: BrowserClipboard
+```
+
+Use `context.clipboard` to read and write clipboard text, paste into focused elements, or copy and cut selected content. See the [clipboard reference](/v3/references/clipboard) for the full API.

+
+## Working with Active Pages
+
+The context tracks which page is currently active:
+
+```typescript
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+
+// Get the current active page
+const activePage = stagehand.context.activePage();
+
+// Create a new page - it becomes active
+const newPage = await stagehand.context.newPage();
+
+// Now context.activePage() returns newPage
+await newPage.goto("https://example.com");
+```
+
+## Relationship Between Context and Page
+
+- **Context** manages the browser-level state and multiple pages
+- **Page** represents a single tab/window with content
+- Creating a new page via `context.newPage()` automatically sets it as active
+- You can explicitly control the active page with `context.setActivePage()`
+- Use `context.activePage()` to get the currently active page
+
+```typescript
+// Get the active page
+const activePage = stagehand.context.activePage();
+
+// Or get the first page directly
+const firstPage = stagehand.context.pages()[0];
+```
+
+## Best Practices
+
+1. **Create pages explicitly** - Use `context.newPage()` instead of relying on popups or window.open
+2. **Track page references** - Store page objects in variables for easier management
+3. **Set active page before operations** - Ensure the correct page is active before calling Stagehand methods
+4. **Clean up properly** - Call `stagehand.close()` to close all pages and the context
+5. **Handle page order** - Remember that `context.pages()` returns pages in creation order
+6. **Use parallel operations** - Work with multiple pages simultaneously for better performance
+
+## Common Patterns
+
+### Tab Management
+
+```typescript
+// Keep track of pages by purpose
+const pages = {
+  home: await context.newPage("https://example.com"),
+  dashboard: await context.newPage("https://example.com/dashboard"),
+  settings: await context.newPage("https://example.com/settings")
+};
+
+// Switch between tabs
+context.setActivePage(pages.dashboard);
+await stagehand.act("view report");
+
+context.setActivePage(pages.settings);
+await stagehand.act("update preferences");
+```
+
+### Bulk Data Collection
+
+```typescript
+const urls = [
+  "https://site1.com",
+  "https://site2.com",
+  "https://site3.com"
+];
+
+// Open all pages
+const pages = await Promise.all(
+  urls.map(url => context.newPage(url))
+);
+
+// Extract data from each
+const data = await Promise.all(
+  pages.map(page => stagehand.extract("get data", schema, { page }))
+);
+```
+
+### Conditional Page Management
+
+```typescript
+// Only create a page if needed
+if (needsDashboard) {
+  const dashboard = await context.newPage("https://example.com/dashboard");
+  context.setActivePage(dashboard);
+  await stagehand.act("generate report");
+}
+
+// Check if we have multiple pages
+if (context.pages().length > 1) {
+  console.log("Multiple tabs open");
+}
+```
+
+## Error Handling
+
+Context methods may throw the following errors:
+
+- **Timeout errors** - `newPage()` timeout waiting for page to attach
+- **CDP errors** - Connection errors with Chrome DevTools Protocol
+- **Invalid page errors** - Attempting to set an active page that doesn't exist in the context
+- **StagehandSetExtraHTTPHeadersError** - `setExtraHTTPHeaders()` failed to apply headers to one or more sessions. The error includes a `failures` array with per-session details
+- **StagehandInvalidArgumentError** - `setDomainPolicy()` received an invalid policy, such as a URL instead of a domain-only pattern
+- **StagehandSetDomainPolicyError** - `setDomainPolicy()` failed to enable or disable enforcement for one or more sessions. The error includes a `failures` array with per-session details
+
+Always handle errors appropriately:
+
+```typescript
+try {
+  const page = await context.newPage("https://example.com");
+} catch (error) {
+  console.error("Failed to create page:", error.message);
+}
+```
+
+## Type Definitions
+
+```typescript
+interface V3Context {
+  newPage(url?: string): Promise<Page>;
+  pages(): Page[];
+  activePage(): Page | undefined;
+  setActivePage(page: Page): void;

+  cookies(urls?: string | string[]): Promise<Cookie[]>;
+  addCookies(cookies: CookieParam[]): Promise<void>;
+  clearCookies(options?: ClearCookieOptions): Promise<void>;
+  close(): Promise<void>;

+  Learn about the standard Locator class
+</Card>
+</CardGroup>
+
+## Overview
+
+The `deepLocator()` method creates a special locator that can traverse iframe boundaries and shadow DOM using a simplified syntax. It automatically resolves the correct frame for each operation, making cross-frame interactions seamless.
+
+Access via the page object:
+
+```typescript
+const stagehand = new Stagehand({ env: "BROWSERBASE" });
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+// Deep locator with iframe traversal
+const button = page.deepLocator("iframe#myframe >> button.submit");
+await button.click();
+```
+
+## Syntax
+
+### page.deepLocator()
+
+Create a deep locator that can cross iframe and shadow DOM boundaries.
+
+```typescript
+page.deepLocator(selector: string): DeepLocatorDelegate
+```
+
+<ParamField path="selector" type="string" required>
+  Selector string with optional iframe hop notation (`>>`).
+
+  Supports:
+  - **CSS selectors** - Standard CSS syntax
+  - **XPath** - Prefix with `xpath=` or start with `/`
+  - **Hop notation** - Use `>>` to traverse into iframes
+  - **Deep XPath** - Automatically handles iframe steps in XPath
+</ParamField>
+
+**Returns:** `DeepLocatorDelegate` - A locator-like object that resolves frames on each action.
+
+## Hop Notation
+
+The `>>` operator allows you to traverse into iframes in a readable way:
+
+```typescript
+// Syntax: parent-selector >> child-selector >> target-selector
+page.deepLocator("iframe#outer >> iframe.inner >> button")
+```
+
+Each segment before `>>` represents an iframe to traverse into. The final segment is the target element.
+
+### Examples
+
+```typescript
+// Single iframe hop
+page.deepLocator("iframe#payment >> input#card-number")
+
+// Multiple iframe hops
+page.deepLocator("iframe#level1 >> iframe#level2 >> div.content")
+
+// XPath with hops
+page.deepLocator("//iframe[@id='myframe'] >> //button[@class='submit']")
+
+// CSS with XPath target
+page.deepLocator("iframe.widget >> xpath=//div[@data-id='123']")
+```
+
+## Deep XPath
+
+When using XPath, `deepLocator` automatically recognizes `iframe` steps and traverses into them:
+
+```typescript
+// Automatically traverses into iframes
+page.deepLocator("//iframe//button")
+page.deepLocator("//iframe[@id='myframe']//input[@name='email']")
+page.deepLocator("//iframe[1]//iframe[2]//div[@class='target']")
+```
+
+The locator intelligently parses the XPath, identifies iframe boundaries, and resolves the correct frame for the final selector.
+
+## Methods
+
+`DeepLocatorDelegate` provides the same API as `Locator`, with automatic frame resolution:
+
+### Interaction Methods
+
+All interaction methods from [`Locator`](/v3/references/locator) are available:
+
+- **`click(options?)`** - Click the element
+- **`fill(value)`** - Fill an input
+- **`type(text, options?)`** - Type text
+- **`hover()`** - Hover over element
+- **`selectOption(values)`** - Select dropdown options
+- **`scrollTo(percent)`** - Scroll element
+
+### State Methods
+
+- **`isVisible()`** - Check visibility
+- **`isChecked()`** - Check checkbox state
+- **`inputValue()`** - Get input value
+- **`textContent()`** - Get text content
+- **`innerText()`** - Get visible text
+- **`innerHtml()`** - Get HTML content
+
+### Selection Methods
+
+- **`count()`** - Count matching elements
+- **`nth(index)`** - Select by index
+- **`first()`** - Get first element
+
+### Utility Methods
+
+- **`highlight(options?)`** - Highlight element
+- **`centroid()`** - Get center coordinates
+- **`backendNodeId()`** - Get DOM node ID
+- **`sendClickEvent(options?)`** - Dispatch click event
+
+All methods work identically to `Locator`, but automatically resolve the correct frame before executing.

+
+## Comparison with Standard Locator
+
+### Standard Locator (Single Frame)
+
+```typescript
+// Only works in the main frame
+const button = page.locator("button.submit");
+await button.click();
+
+// Cannot access elements inside iframes
+const iframeButton = page.locator("iframe >> button"); // ❌ Won't work
+```
+
+### Deep Locator (Cross-Frame)
+
+```typescript
+// Works across iframe boundaries
+const button = page.deepLocator("iframe#widget >> button.submit");
+await button.click(); // ✅ Automatically traverses into iframe
+
+// Can handle nested iframes
+const nested = page.deepLocator("iframe#a >> iframe#b >> button");
+await nested.click(); // ✅ Handles multiple levels
+```
+
+## When to Use deepLocator
+
+Use `deepLocator()` when:
+
+1. **Targeting elements inside iframes** - Payment forms, embedded widgets, third-party content
+2. **Working with nested iframes** - Multiple levels of iframe nesting
+3. **XPath crosses iframe boundaries** - When XPath naturally includes iframe steps
+4. **Simpler syntax preferred** - Use `>>` instead of manual frame switching
+
+Use standard `locator()` when:
+
+1. **Elements are in main frame** - No iframe traversal needed
+2. **Performance critical** - Standard locator is slightly faster (no frame resolution)
+3. **Working with frame references** - You already have the frame object
+
+## Best Practices
+
+1. **Use specific selectors** - Make each segment unique to avoid ambiguity
+2. **Keep hop chains short** - Simpler is better for maintainability
+3. **Name your iframes** - Use IDs or classes on iframes for easier targeting
+4. **Test incrementally** - Verify each segment works before adding more
+5. **Cache selectors** - Store complex selectors in variables for reuse
+6. **Use highlight() for debugging** - Verify you're targeting the right element
+
+## Common Patterns
+
+### Named Iframe References
+
+```typescript
+// Define iframe selectors
+const PAYMENT_FRAME = "iframe#stripe-payment";
+const WIDGET_FRAME = "iframe.embedded-widget";
+
+// Use in deep locators
+await page.deepLocator(`${PAYMENT_FRAME} >> input#card`).fill("4242");
+await page.deepLocator(`${WIDGET_FRAME} >> button`).click();
+```
+
+### Conditional Iframe Interaction
+
+```typescript
+const errorInIframe = page.deepLocator("iframe#form >> .error-message");
+if (await errorInIframe.isVisible()) {
+  const errorText = await errorInIframe.textContent();
+  console.error("Form error:", errorText);
+}
+```
+
+### Dynamic Frame Selection
+
+```typescript
+// Select iframe by attribute
+const frameSelector = `iframe[data-widget-id="${widgetId}"]`;
+const button = page.deepLocator(`${frameSelector} >> button.action`);
+await button.click();
+```
+
+## Error Handling
+
+Deep locator operations may throw:
+
+- **Element not found** - Selector doesn't match in the target frame
+- **Frame not found** - Iframe selector doesn't resolve
+- **Timeout errors** - Frame or element resolution timed out
+- **Invalid selector** - Malformed selector syntax
+
+Handle errors appropriately:
+
+```typescript
+try {
+  await page.deepLocator("iframe#widget >> button").click();
+} catch (error) {
+  console.error("Deep locator failed:", error.message);
+  // Fallback or retry logic
+}
+```
+
+## Advanced Usage
+
+### Combining with Page Methods
+
+```typescript
+// Navigate then use deep locator
+await page.goto("https://example.com");
+await page.waitForLoadState("networkidle");
+
+const iframeButton = page.deepLocator("iframe#app >> button");
+await iframeButton.click();
+```
+
+### With AI-Powered Methods
+
+```typescript
+// Use observe to find elements in iframes
+const actions = await stagehand.observe("find buttons in the payment iframe");
+
+// Then use deep locator for precise interaction
+await page.deepLocator("iframe#payment >> button.submit").click();
+```
+
+## Technical Details
+
+### How It Works
+
+1. **Parse selector** - Splits on `>>` or parses XPath for iframe steps
+2. **Build frame chain** - Creates FrameLocator chain for each iframe segment
+3. **Resolve final frame** - Navigates through frames to find target frame
+4. **Create locator** - Returns a locator in the correct frame context
+5. **Lazy execution** - Frame resolution happens fresh on each action
+
+### Frame Resolution
+
+Deep locators use the internal `FrameLocator` and `resolveLocatorWithHops` logic to:
+
+- Track frame hierarchies
+- Handle OOPIF (out-of-process iframes)
+- Support shadow DOM piercing
+- Maintain frame references during navigation

+</Card>
+</CardGroup>
+
+## Overview
+
+The `Locator` class provides precise element interaction capabilities. It resolves CSS or XPath selectors within a frame and performs low-level actions using Chrome DevTools Protocol (CDP).
+
+Create a locator through the page object:
+
+```typescript
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+
+// Create a locator
+const button = page.locator("button.submit");
+await button.click();
+```
+
+## Key Features
+
+- **Lazy resolution** - Selectors are resolved fresh on each action
+- **Isolated execution** - Runs in an isolated world, separate from page scripts
+- **CDP-based** - Uses Chrome DevTools Protocol for reliable interactions
+- **Automatic cleanup** - Releases remote objects automatically
+- **Iframe support** - Works seamlessly with iframes and shadow DOM
+

+  borderColor: { r: 255, g: 0, b: 0 },
+  contentColor: { r: 255, g: 0, b: 0, a: 0.1 }

+
+// Get element position
+const { x, y } = await section.centroid();
+console.log(`Element center: ${x}, ${y}`);
+```
+
+</Tab>
+</Tabs>
+
+## Selector Support
+
+Locators support both CSS and XPath selectors:
+
+### CSS Selectors
+
+```typescript
+page.locator("button");                    // Tag
+page.locator(".submit-btn");              // Class
+page.locator("#login-form");              // ID
+page.locator("button.primary");           // Tag + class
+page.locator("input[type=email]");        // Attribute
+page.locator("div > p");                  // Child
+page.locator("h1 + p");                   // Adjacent sibling
+page.locator("div.container button");     // Descendant
+```
+
+### XPath Selectors
+
+```typescript
+page.locator("//button");                               // Tag
+page.locator("//button[@class='submit']");             // Attribute
+page.locator("//div[@id='content']//p");               // Descendant
+page.locator("//button[contains(text(), 'Submit')]");  // Text content
+page.locator("(//button)[1]");                         // First button
+page.locator("//input[@type='text'][1]");              // First text input
+```
+
+## Best Practices
+
+1. **Use specific selectors** - Prefer IDs or unique attributes over generic selectors
+2. **Chain with nth()** - Use `locator().nth()` instead of putting index in selector
+3. **Check state before action** - Use `isVisible()`, `isChecked()` for conditional logic
+4. **Let locators auto-resolve** - Don't store element handles, use locators which re-resolve
+5. **Use fill() for inputs** - Prefer `fill()` over `click()` + `type()` for better reliability
+6. **Handle file uploads properly** - Use absolute paths or buffer payloads for `setInputFiles()`
+7. **Highlight for debugging** - Use `highlight()` during development to verify targeting
+
+## Common Patterns
+
+### Conditional Interaction
+
+```typescript
+const errorMessage = page.locator(".error-message");
+if (await errorMessage.isVisible()) {
+  const text = await errorMessage.textContent();
+  console.log("Error:", text);
+}
+```
+
+### Wait and Interact
+
+```typescript
+// Locators automatically wait during actions
+const dynamicButton = page.locator("button.dynamic");
+await dynamicButton.click(); // Waits for element to exist
+```
+
+### Loop Through Elements
+
+```typescript
+const items = page.locator("li.item");
+const count = await items.count();
+
+for (let i = 0; i < count; i++) {
+  const item = items.nth(i);
+  const text = await item.innerText();
+  console.log(`Item ${i}:`, text);
+}
+```
+
+## Error Handling
+
+Locator methods may throw the following errors:
+
+- **Element not found** - Selector doesn't match any elements
+- **Element not visible** - Element exists but is not visible (for actions requiring visibility)
+- **Invalid selector** - Malformed CSS or XPath selector
+- **Timeout errors** - Operation exceeded timeout limits
+- **CDP errors** - Chrome DevTools Protocol communication errors
+
+Handle errors appropriately:
+
+```typescript
+try {
+  await page.locator("button.submit").click();
+} catch (error) {
+  console.error("Click failed:", error.message);
+}
+```
+
+## Type Definitions
+
+```typescript
+interface Locator {
+  // Actions
+  click(options?: { button?: MouseButton; clickCount?: number }): Promise<void>;
+  fill(value: string): Promise<void>;
+  type(text: string, options?: { delay?: number }): Promise<void>;
+  hover(): Promise<void>;
+  selectOption(values: string | string[]): Promise<string[]>;
+  setInputFiles(files: FileInput): Promise<void>;
+
+  // State
+  isVisible(): Promise<boolean>;
+  isChecked(): Promise<boolean>;
+  inputValue(): Promise<string>;
+  textContent(): Promise<string>;
+  innerText(): Promise<string>;
+  innerHtml(): Promise<string>;
+
+  // Selection
+  count(): Promise<number>;
+  nth(index: number): Locator;
+  first(): Locator;
+
+  // Utilities
+  highlight(options?: HighlightOptions): Promise<void>;
+  scrollTo(percent: number | string): Promise<void>;
+  centroid(): Promise<{ x: number; y: number }>;
+  backendNodeId(): Promise<BackendNodeId>;
+  sendClickEvent(options?: EventOptions): Promise<void>;
+}

+```
+
+</Tab>
+
+</Tabs>
+
+### Parameters
+
+<ParamField path="instruction" type="string" required>
+  Natural language description of elements or actions to discover. If not provided, defaults to finding all interactive elements on the page.
+</ParamField>
+
+<ParamField path="model" type="ModelConfiguration" optional>
+  Configure the AI model to use for this observation. Can be either:
+  - A string in the format `"provider/model"` (e.g., `"openai/gpt-4o"`, `"anthropic/claude-sonnet-4-6"`)
+  - An object with detailed configuration
+
+  <Expandable title="Model Configuration Object">
+    <ParamField path="modelName" type="string" required>
+      The model name (e.g., "gpt-4o", "claude-sonnet-4-6", "gemini-2.5-flash")
+    </ParamField>
+    <ParamField path="apiKey" type="string" optional>
+      API key for the model provider (overrides default)
+    </ParamField>
+    <ParamField path="baseURL" type="string" optional>

+  </Expandable>
+</ParamField>
+
+<ParamField path="variables" type="Record<string, VariableValue>" optional>
+  Key-value pairs for placeholder generation using `%variableName%` syntax in returned action arguments. `observe()` exposes only the placeholder names to the model and returns `Action[]` that still contain `%variableName%` tokens so you can validate them before executing with `act()`.
+
+  Values can be simple primitives (`string`, `number`, `boolean`) or rich objects with an optional description (`{ value, description? }`).
+</ParamField>
+
+<ParamField path="timeout" type="number" optional>
+  Maximum time in milliseconds to wait for the observation to complete. Default varies by configuration.
+</ParamField>
+
+<ParamField path="selector" type="string" optional>
+  Optional XPath selector to focus the observation on a specific part of the page. Useful for narrowing down the search area.
+</ParamField>
+
+<ParamField path="ignoreSelectors" type="string[]" optional>
+  Optional list of selectors to exclude from the observed snapshot before observation runs. Each selector removes all matching elements and their descendants.
+
+  <Note>
+    `ignoreSelectors` applies to all matches for each selector. `selector` keeps its single-target scoping behavior.
+  </Note>
+</ParamField>
+
+<ParamField path="page" type="PlaywrightPage | PuppeteerPage | PatchrightPage | Page" optional>
+  Optional: Specify which page to perform the observation on. Supports multiple browser automation libraries:
+  - **Playwright**: Native Playwright Page objects
+  - **Puppeteer**: Puppeteer Page objects
+  - **Patchright**: Patchright Page objects
+  - **Stagehand Page**: Stagehand's wrapped Page object
+
+  If not specified, defaults to the current "active" page in your Stagehand instance.
+</ParamField>
+
+<ParamField path="serverCache" type="boolean" optional>
+  Override the instance-level `serverCache` setting for this request. When `true`, enables server-side caching. When `false`, disables it.
+
+  <Note>Only applies when `env` is `"BROWSERBASE"`. Has no effect in local environments.</Note>
+
+  Defaults to the value set on the Stagehand constructor (which itself defaults to `true`).
+</ParamField>
+
+### Returns `Promise<Action[]>`
+
+Array of discovered actionable elements, ordered by relevance.
+
+<ResponseField name="selector" type="string">

+This method:
+- Runs at document start for the current page (including adopted iframe sessions) on every navigation
+- Reinstalls the script for all future navigations of this page without affecting other pages
+- Mirrors Playwright's `page.addInitScript()` ordering semantics; use  [`context.addInitScript()`](/v3/references/context#addinitscript) to target every page in the context
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+const context = stagehand.context;
+const page = await context.awaitActivePage();

+This method:
+- Applies the headers to the page's main CDP session and all of its child sessions (e.g. out-of-process iframes)
+- Automatically applies the same headers to any child sessions adopted after calling `setExtraHTTPHeaders()`
+- Calling it again replaces all previously set extra headers (it does not merge)
+- To clear all extra headers, pass an empty object: `await page.setExtraHTTPHeaders({})`
+
+<Note>
+Headers set via `page.setExtraHTTPHeaders()` are page-scoped. They apply to every network request from this page only, including navigation requests, XHR/fetch calls, and subresource loads. Use [`context.setExtraHTTPHeaders()`](/v3/references/context#setextrahttpheaders) to set headers across all pages in the context.
+</Note>
+
+```typescript
+import { Stagehand } from "@browserbasehq/stagehand";
+
+const stagehand = new Stagehand({ env: "LOCAL" });
+await stagehand.init();
+const page = stagehand.context.pages()[0];
+

+## Events
+
+### on("console")
+
+Listen for console output produced by the page and any adopted iframe sessions. Returns the page instance so calls can be chained.
+
+```typescript
+import type { ConsoleMessage } from "@browserbasehq/stagehand";
+

+  console.log(`[${message.type()}] ${message.text()}`);
+  console.log("Arguments:", message.args());
+  const location = message.location();
+  if (location?.url) {
+    console.log(`Emitted from ${location.url}:${location.lineNumber ?? 0}`);
+  }
+};
+
+page.on("console", handleConsole);
+```
+
+`ConsoleMessage` exposes helpers for working with console events:
+
+- `message.type()` – console API category such as `log`, `error`, or `warning`
+- `message.text()` – string representation of the console arguments
+- `message.args()` – underlying CDP `RemoteObject` arguments array
+- `message.location()` – source URL, line, and column when available
+- `message.timestamp()` – CDP timestamp for the event
+- `message.raw()` – access to the original `Runtime.consoleAPICalledEvent`
+
+### once("console")
+
+Register a listener that removes itself after the first console event.
+
+```typescript
+page.once("console", (message) => {
+  console.log("First console message:", message.text());
+});
+```
+
+### off("console")
+
+Remove a previously registered listener. The reference must match the original listener passed to `on()`.
+
+```typescript
+page.off("console", handleConsole);
+```

+  See how pages expose Response objects from navigation methods
+</Card>
+</CardGroup>
+
+## Overview
+
+`Response` mirrors Playwright’s [Response](https://playwright.dev/docs/api/class-response) interface and is returned from Stagehand navigation helpers such as `page.goto()`, `page.reload()`, `page.goBack()`, and `page.goForward()`. It provides a convenient way to inspect the HTTP metadata associated with a navigation, retrieve the response body on demand, and monitor when the underlying request finishes.
+
+Stagehand automatically returns `null` for navigations that do not yield a network request (for example `data:` URLs, `about:blank`, or same-document history changes), matching Playwright’s behaviour.
+
+## Getting a Response
+
+```typescript
+const response = await page.goto("https://example.com", {
+  waitUntil: "networkidle",
+});
+
+if (!response) {
+  throw new Error("Navigation did not produce a network response");
+}
+
+console.log("Status", response.status(), response.statusText());
+const body = await response.text();
+```
+
+When a navigation does not produce a response object you will receive `null`, allowing you to branch early:
+
+```typescript
+const inline = await page.goto("data:text/html,<h1>inline</h1>");
+if (inline === null) {
+  // No network fetch happened; handle accordingly
+}
+```
+
+## Status & Metadata
+
+### url()
+
+```typescript
+response.url(): string
+```
+
+Returns the final URL associated with the navigation request.
+
+### status()
+
+```typescript
+response.status(): number
+```
+
+Returns the HTTP status code.
+
+### statusText()
+
+```typescript
+response.statusText(): string
+```
+
+Returns the human-readable status text (for example `OK`).
+
+### ok()
+
+```typescript
+response.ok(): boolean
+```
+
+Convenience helper that resolves to `true` for 2xx responses and `false` otherwise.
+
+### frame()
+
+```typescript
+response.frame(): Frame | null
+```
+
+Returns the Stagehand `Frame` that initiated the navigation. When the frame is no longer available, `null` is returned.
+
+### fromServiceWorker()
+
+```typescript
+response.fromServiceWorker(): boolean
+```
+
+Indicates whether the response was served from a Service Worker fetch handler.
+
+### securityDetails()
+
+```typescript
+await response.securityDetails(): Promise<Protocol.Network.SecurityDetails | null>
+```
+
+Resolves with TLS/security metadata when available (issuer, protocol, validity window). Returns `null` for insecure or non-network responses.
+
+### serverAddr()
+
+```typescript
+await response.serverAddr(): Promise<{ ipAddress: string; port: number } | null>
+```
+
+Provides the remote IP/port reported by Chrome, when known.
+
+## Header Helpers
+
+### headers()
+
+```typescript
+response.headers(): Record<string, string>
+```
+
+Returns a lowercase header map, matching Playwright’s `headers()` behaviour.
+
+### allHeaders()
+
+```typescript
+await response.allHeaders(): Promise<Record<string, string>>
+```
+
+Includes additional headers only surfaced via Chrome’s `responseReceivedExtraInfo` event (such as `set-cookie`).
+
+### headerValue()
+
+```typescript
+await response.headerValue(name: string): Promise<string | null>
+```
+
+Returns a comma-joined string of all values for the specified header. Resolves to `null` when the header is absent.
+
+### headerValues()
+
+```typescript
+await response.headerValues(name: string): Promise<string[]>
+```
+
+Returns an array of header values, keeping multiple entries separate.
+
+### headersArray()
+
+```typescript
+await response.headersArray(): Promise<Array<{ name: string; value: string }>>
+```
+
+Returns the header list while preserving the original casing and order reported by the browser.
+
+## Body Helpers
+
+### body()
+
+```typescript
+await response.body(): Promise<Buffer>
+```
+
+Fetches the raw response body. The buffer is base64-decoded for you when Chrome sends it that way.
+
+### text()
+
+```typescript
+await response.text(): Promise<string>
+```
+
+Returns the response body decoded as UTF-8 text.
+
+### json()
+
+```typescript
+await response.json<T = unknown>(): Promise<T>
+```
+
+Parses the response body as JSON. Throws if the body cannot be parsed or is not valid JSON.
+
+<Note>
+All body helper calls (`body()`, `text()`, `json()`) only succeed once the browser reports the response body is available. Stagehand handles this timing automatically.
+</Note>
+
+## Completion
+
+### finished()
+
+```typescript
+await response.finished(): Promise<null | Error>
+```
+
+Resolves to `null` when the main navigation request completes successfully, or to an `Error` if Chrome reports `Network.loadingFailed`. This mirrors Playwright’s `response.finished()` contract and is especially helpful for catching late failures such as network resets or blocked responses.
+
+```typescript
+const result = await response.finished();
+if (result instanceof Error) {
+  console.error("Navigation failed", result.message);
+}
+```
+
+## Usage Patterns
+
+### Inspect status and headers
+
+```typescript
+const response = await page.goto("https://httpbin.org/headers");
+
+if (response) {
+  console.log(response.status(), response.statusText());
+  const headers = await response.headersArray();
+  headers.forEach(({ name, value }) => {
+    console.log(`${name}: ${value}`);
+  });
+}
+```
+
+### Handle non-network navigations
+
+```typescript
+const result = await page.goto("data:text/html,<p>inline</p>");
+
+if (result === null) {
+  console.log("No network response (data URL)");
+} else {
+  // Process as usual
+}
+```
+
+### Await completion
+
+```typescript
+const response = await page.goto("https://example.com/slow");
+
+if (response) {
+  const finished = await response.finished();
+  if (finished instanceof Error) {
+    console.error("Navigation failed", finished.message);
+  }
+}
+```
+
+## Returned From
+
+- `await page.goto(url, options?)`
+- `await page.reload(options?)`
+- `await page.goBack(options?)`
+- `await page.goForward(options?)`
+
+Each method resolves with `Response | null` depending on whether Chrome reported a document-level network response.

+## Methods
+
+### init()
+
+Initialize the Stagehand instance and launch the browser.
+
+```typescript
+await stagehand.init(): Promise<void>
+```
+
+**Must be called before using any other methods.**
+
+### close()
+
+Close the browser and clean up resources.
+
+```typescript
+await stagehand.close(options?: { force?: boolean }): Promise<void>
+```
+
+<ParamField path="force" type="boolean" optional>
+  Force close even if already closing.
+
+  **Default:** `false`
+</ParamField>
+
+<Note>
+When `keepAlive` is `true`, calling `close()` disconnects Stagehand from the browser without terminating it. The browser session continues running independently and can be reconnected to later using `browserbaseSessionID`. When `keepAlive` is `false` (the default), `close()` fully terminates the browser and cleans up all resources.
+</Note>
+
+### agent()
+
+Create an AI agent instance for autonomous multi-step workflows.
+
+```typescript
+stagehand.agent(config?: AgentConfig): AgentInstance
+```
+
+See the [agent() reference](/v3/references/agent) for detailed documentation.
+
+## Properties
+
+### page
+
+Access pages for browser automation. Pages are accessed through the context.
+
+```typescript
+// Get the first page (created automatically on init)
+const page = stagehand.context.pages()[0];
+
+// Or get the active page
+const activePage = stagehand.context.activePage();
+
+// Create a new page
+const newPage = await stagehand.context.newPage();
+```
+
+**Type:** [`Page`](/v3/references/page)
+
+The page object provides methods for:
+- Navigation (`goto()`, `reload()`, `goBack()`, `goForward()`)
+- Interaction (`click()`, `type()`, `keyPress()`, `locator()`, `deepLocator()`)
+- Inspection (`url()`, `title()`, `screenshot()`)
+- JavaScript evaluation (`evaluate()`)
+
+<Note>
+**Important:** AI-powered methods ([`act()`](/v3/references/act), [`extract()`](/v3/references/extract), [`observe()`](/v3/references/observe)) are called on the stagehand instance, not on the page object.
+</Note>
+
+### context
+
+Access the browser context for managing multiple pages.
+
+```typescript
+const context = stagehand.context;
+```
+
+**Type:** `V3Context`
+
+The context object provides:
+- `newPage()` - Create a new page/tab
+- `pages()` - Get all open pages
+- `setActivePage(page)` - Switch active page
+
+### metrics
+
+Get usage metrics for AI operations.
+
+```typescript
+const metrics = await stagehand.metrics;

+
+## Error Handling
+
+Stagehand methods may throw the following errors:
+
+- **StagehandInitError** - Failed to initialize Stagehand
+- **StagehandNotInitializedError** - Methods called before `init()`
+- **BrowserbaseSessionNotFoundError** - Browserbase session not found
+- **MissingLLMConfigurationError** - No LLM API key or client configured
+- **MissingEnvironmentVariableError** - Required environment variable not set
+- **StagehandEnvironmentError** - Invalid environment configuration
+
+Always handle errors appropriately:
+
+```typescript
+try {
+  const stagehand = new Stagehand({ env: "LOCAL" });
+  await stagehand.init();
+  // ... use stagehand
+} catch (error) {
+  console.error("Stagehand error:", error.message);
+} finally {
+  await stagehand?.close();
+}
+```
+
+## Best Practices
+
+1. **Always call `init()`** before using any other methods
+2. **Always call `close()`** when done to clean up resources
+3. **Use try-finally** to ensure cleanup even on errors
+4. **Set appropriate timeouts** based on your use case
+5. **Enable `selfHeal`** for more robust automation
+6. **Use metrics** to monitor token usage and costs
+7. **Configure custom logger** for production debugging
+8. **Cache directory** can significantly improve performance for repeated actions
+
+## Environment Variables
+
+Stagehand recognizes the following environment variables:
+
+- `BROWSERBASE_API_KEY` - Browserbase API key
+- `OPENAI_API_KEY` - OpenAI API key
+- `ANTHROPIC_API_KEY` - Anthropic API key
+- `GOOGLE_API_KEY` - Google AI API key
+
+These can be overridden by passing values in the constructor options.

+
+## What is Stagehand?
+
+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
+## Why Stagehand?
+
+Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language (and bridging the gap between the two) Stagehand is the natural choice for browser automations in production.
+
+1. **Choose when to write code vs. natural language**: use AI when you want to navigate unfamiliar pages, and use code when you know exactly what you want to do.
+
+2. **Go from AI-driven to repeatable workflows**: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.
+
+3. **Write once, run forever**: Stagehand's auto-caching combined with self-healing remembers previous actions, runs without LLM inference, and knows when to involve AI whenever the website changes and your automation breaks.
+
+## Installation
+
+```go
+import (
+	"github.com/browserbase/stagehand-go" // imported as stagehand
+)
+```
+
+Or to pin the version:
+
+```sh
+go get -u 'github.com/browserbase/stagehand-go@v0.17.1'
+```
+
+## Requirements
+
+This library requires Go 1.22+.
+
+## Usage
+
+The full API of this library can be found in [api.md](https://github.com/browserbase/stagehand-go/blob/main/api.md).
+
+```go
+package main
+
+import (
+	"context"
+	"fmt"
+
+	"github.com/browserbase/stagehand-go"
+	"github.com/browserbase/stagehand-go/option"
+)
+
+func main() {
+	// Create a new Stagehand client with your credentials
+	client := stagehand.NewClient(
+		option.WithBrowserbaseAPIKey("My Browserbase API Key"), // defaults to os.LookupEnv("BROWSERBASE_API_KEY")
+		option.WithModelAPIKey("My Model API Key"),             // defaults to os.LookupEnv("MODEL_API_KEY")
+	)
+
+	// Start a new browser session
+	startResponse, err := client.Sessions.Start(context.TODO(), stagehand.SessionStartParams{

+
+	// Extract structured data from the page using a JSON schema
+	extractResponse, err := client.Sessions.Extract(
+		context.TODO(),
+		sessionID,
+		stagehand.SessionExtractParams{
+			Instruction: stagehand.String("extract the text of the top comment"),
+			Schema: map[string]any{
+				"type": "object",

+		panic(err.Error())
+	}
+	fmt.Println("Session ended")
+}
+```
+
+### Running the example
+
+A complete working example is available in `examples/basic.go`. To run it:
+
+1. **Set up environment variables** by creating a `.env` file in the repository root:
+
+```bash
+BROWSERBASE_API_KEY=your_browserbase_api_key
+MODEL_API_KEY=your_openai_api_key
+```
+
+You can get your Browserbase API key from the [Browserbase dashboard](https://www.browserbase.com/).
+
+2. **Install dependencies**:
+
+```bash
+go mod tidy
+```
+
+3. **Run the example**:
+
+```bash
+go run examples/basic.go
+```
+
+The example demonstrates the full Stagehand workflow: starting a session, navigating to a page, observing actions, clicking elements, extracting data, and running an autonomous agent.
+
+### Request fields
+
+The stagehand library uses the [`omitzero`](https://tip.golang.org/doc/go1.24#encodingjsonpkgencodingjson)
+semantics from the Go 1.24+ `encoding/json` release for request fields.
+
+Required primitive fields (`int64`, `string`, etc.) feature the tag `json:"...,required"`. These
+fields are always serialized, even their zero values.
+
+Optional primitive types are wrapped in a `param.Opt[T]`. These fields can be set with the provided constructors, `stagehand.String(string)`, `stagehand.Int(int64)`, etc.
+
+Any `param.Opt[T]`, map, slice, struct or string enum uses the
+tag `json:"...,omitzero"`. Its zero value is considered omitted.
+
+The `param.IsOmitted(any)` function can confirm the presence of any `omitzero` field.
+
+```go
+p := stagehand.ExampleParams{
+	ID:   "id_xxx",                // required property
+	Name: stagehand.String("..."), // optional property
+
+	Point: stagehand.Point{
+		X: 0,                // required field will serialize as 0
+		Y: stagehand.Int(1), // optional field will serialize as 1
+		// ... omitted non-required fields will not be serialized
+	},
+
+	Origin: stagehand.Origin{}, // the zero value of [Origin] is considered omitted
+}
+```
+
+To send `null` instead of a `param.Opt[T]`, use `param.Null[T]()`.
+To send `null` instead of a struct `T`, use `param.NullStruct[T]()`.
+
+```go
+p.Name = param.Null[string]()       // 'null' instead of string
+p.Point = param.NullStruct[Point]() // 'null' instead of struct
+
+param.IsNull(p.Name)  // true
+param.IsNull(p.Point) // true
+```
+
+Request structs contain a `.SetExtraFields(map[string]any)` method which can send non-conforming
+fields in the request body. Extra fields overwrite any struct fields with a matching
+key. For security reasons, only use `SetExtraFields` with trusted data.
+
+To send a custom value instead of a struct, use `param.Override[T](https://github.com/browserbase/stagehand-go/blob/main/value)`.
+
+```go
+// In cases where the API specifies a given type,
+// but you want to send something else, use [SetExtraFields]:
+p.SetExtraFields(map[string]any{
+	"x": 0.01, // send "x" as a float instead of int
+})
+
+// Send a number instead of an object
+custom := param.Override[stagehand.FooParams](https://github.com/browserbase/stagehand-go/blob/main/12)
+```
+
+### Request unions
+
+Unions are represented as a struct with fields prefixed by "Of" for each of its variants,
+only one field can be non-zero. The non-zero field will be serialized.
+
+Sub-properties of the union can be accessed via methods on the union struct.
+These methods return a mutable pointer to the underlying data, if present.
+
+```go
+// Only one field can be non-zero, use param.IsOmitted() to check if a field is set
+type AnimalUnionParam struct {
+	OfCat *Cat `json:",omitzero,inline`
+	OfDog *Dog `json:",omitzero,inline`
+}
+
+animal := AnimalUnionParam{
+	OfCat: &Cat{
+		Name: "Whiskers",
+		Owner: PersonParam{
+			Address: AddressParam{Street: "3333 Coyote Hill Rd", Zip: 0},
+		},
+	},
+}
+
+// Mutating a field
+if address := animal.GetOwner().GetAddress(); address != nil {
+	address.ZipCode = 94304
+}
+```
+
+### Response objects
+
+All fields in response structs are ordinary value types (not pointers or wrappers).
+Response structs also include a special `JSON` field containing metadata about
+each property.
+
+```go
+type Animal struct {
+	Name   string `json:"name,nullable"`
+	Owners int    `json:"owners"`
+	Age    int    `json:"age"`
+	JSON   struct {
+		Name        respjson.Field
+		Owner       respjson.Field
+		Age         respjson.Field
+		ExtraFields map[string]respjson.Field
+	} `json:"-"`
+}
+```
+
+To handle optional data, use the `.Valid()` method on the JSON field.
+`.Valid()` returns true if a field is not `null`, not present, or couldn't be marshaled.
+
+If `.Valid()` is false, the corresponding field will simply be its zero value.
+
+```go
+raw := `{"owners": 1, "name": null}`
+
+var res Animal
+json.Unmarshal([]byte(raw), &res)
+
+// Accessing regular fields
+
+res.Owners // 1
+res.Name   // ""
+res.Age    // 0
+
+// Optional field checks
+
+res.JSON.Owners.Valid() // true
+res.JSON.Name.Valid()   // false
+res.JSON.Age.Valid()    // false
+
+// Raw JSON values
+
+res.JSON.Owners.Raw()                  // "1"
+res.JSON.Name.Raw() == "null"          // true
+res.JSON.Name.Raw() == respjson.Null   // true
+res.JSON.Age.Raw() == ""               // true
+res.JSON.Age.Raw() == respjson.Omitted // true
+```
+
+These `.JSON` structs also include an `ExtraFields` map containing
+any properties in the json response that were not specified
+in the struct. This can be useful for API features not yet
+present in the SDK.
+
+```go
+body := res.JSON.ExtraFields["my_unexpected_field"].Raw()
+```
+
+### Response Unions
+
+In responses, unions are represented by a flattened struct containing all possible fields from each of the
+object variants.
+To convert it to a variant use the `.AsFooVariant()` method or the `.AsAny()` method if present.
+
+If a response value union contains primitive values, primitive fields will be alongside
+the properties but prefixed with `Of` and feature the tag `json:"...,inline"`.
+
+```go
+type AnimalUnion struct {
+	// From variants [Dog], [Cat]
+	Owner Person `json:"owner"`
+	// From variant [Dog]
+	DogBreed string `json:"dog_breed"`
+	// From variant [Cat]
+	CatBreed string `json:"cat_breed"`
+	// ...
+
+	JSON struct {
+		Owner respjson.Field
+		// ...
+	} `json:"-"`
+}
+
+// If animal variant
+if animal.Owner.Address.ZipCode == "" {
+	panic("missing zip code")
+}
+
+// Switch on the variant
+switch variant := animal.AsAny().(type) {
+case Dog:
+case Cat:
+default:
+	panic("unexpected type")
+}
+```
+
+### RequestOptions
+
+This library uses the functional options pattern. Functions defined in the
+`option` package return a `RequestOption`, which is a closure that mutates a
+`RequestConfig`. These options can be supplied to the client or at individual
+requests. For example:
+
+```go
+client := stagehand.NewClient(
+	// Adds a header to every request made by the client
+	option.WithHeader("X-Some-Header", "custom_header_info"),
+)
+
+client.Sessions.Start(context.TODO(), ...,
+	// Override the header
+	option.WithHeader("X-Some-Header", "some_other_custom_header_info"),
+	// Add an undocumented field to the request body, using sjson syntax
+	option.WithJSONSet("some.json.path", map[string]string{"my": "object"}),
+)
+```
+
+The request option `option.WithDebugLog(nil)` may be helpful while debugging.
+
+See the [full list of request options](https://pkg.go.dev/github.com/browserbase/stagehand-go/option).
+
+### Errors
+
+When the API returns a non-success status code, we return an error with type
+`*stagehand.Error`. This contains the `StatusCode`, `*http.Request`, and
+`*http.Response` values of the request, as well as the JSON of the error body
+(much like other response objects in the SDK).
+
+To handle errors, we recommend that you use the `errors.As` pattern:
+
+```go
+_, err := client.Sessions.Start(context.TODO(), stagehand.SessionStartParams{
+	ModelName: "openai/gpt-5-nano",
+})
+if err != nil {
+	var apierr *stagehand.Error
+	if errors.As(err, &apierr) {
+		println(string(apierr.DumpRequest(true)))  // Prints the serialized HTTP request
+		println(string(apierr.DumpResponse(true))) // Prints the serialized HTTP response
+	}
+	panic(err.Error()) // GET "/v1/sessions/start": 400 Bad Request { ... }
+}
+```
+
+When other errors occur, they are returned unwrapped; for example,
+if HTTP transport fails, you might receive `*url.Error` wrapping `*net.OpError`.
+
+### Timeouts
+
+Requests do not time out by default; use context to configure a timeout for a request lifecycle.
+
+Note that if a request is [retried](#retries), the context timeout does not start over.
+To set a per-retry timeout, use `option.WithRequestTimeout()`.
+
+```go
+// This sets the timeout for the request, including all the retries.
+ctx, cancel := context.WithTimeout(context.Background(), 5*time.Minute)
+defer cancel()
+client.Sessions.Start(
+	ctx,
+	stagehand.SessionStartParams{
+		ModelName: "openai/gpt-5-nano",
+	},
+	// This sets the per-retry timeout
+	option.WithRequestTimeout(20*time.Second),
+)
+```
+
+### Retries
+
+Certain errors will be automatically retried 2 times by default, with a short exponential backoff.
+We retry by default all connection errors, 408 Request Timeout, 409 Conflict, 429 Rate Limit,
+and >=500 Internal errors.
+
+You can use the `WithMaxRetries` option to configure or disable this:
+
+```go
+// Configure the default for all requests:
+client := stagehand.NewClient(
+	option.WithMaxRetries(0), // default is 2
+)
+
+// Override per-request:
+client.Sessions.Start(
+	context.TODO(),
+	stagehand.SessionStartParams{
+		ModelName: "openai/gpt-5-nano",
+	},
+	option.WithMaxRetries(5),
+)
+```
+
+### Accessing raw response data (e.g. response headers)
+
+You can access the raw HTTP response data by using the `option.WithResponseInto()` request option. This is useful when
+you need to examine response headers, status codes, or other details.
+
+```go
+// Create a variable to store the HTTP response
+var response *http.Response
+response, err := client.Sessions.Start(
+	context.TODO(),
+	stagehand.SessionStartParams{
+		ModelName: "openai/gpt-5-nano",
+	},
+	option.WithResponseInto(&response),
+)
+if err != nil {
+	// handle error
+}
+fmt.Printf("%+v\n", response)
+
+fmt.Printf("Status Code: %d\n", response.StatusCode)
+fmt.Printf("Headers: %+#v\n", response.Header)
+```
+
+### Making custom/undocumented requests
+
+This library is typed for convenient access to the documented API. If you need to access undocumented
+endpoints, params, or response properties, the library can still be used.
+
+#### Undocumented endpoints
+
+To make requests to undocumented endpoints, you can use `client.Get`, `client.Post`, and other HTTP verbs.
+`RequestOptions` on the client, such as retries, will be respected when making these requests.
+
+```go
+var (
+    // params can be an io.Reader, a []byte, an encoding/json serializable object,
+    // or a "…Params" struct defined in this library.
+    params map[string]any
+
+    // result can be an []byte, *http.Response, a encoding/json deserializable object,
+    // or a model defined in this library.
+    result *http.Response
+)
+err := client.Post(context.Background(), "/unspecified", params, &result)
+if err != nil {
+    …
+}
+```
+
+#### Undocumented request params
+
+To make requests using undocumented parameters, you may use either the `option.WithQuerySet()`
+or the `option.WithJSONSet()` methods.
+
+```go
+params := FooNewParams{
+    ID:   "id_xxxx",
+    Data: FooNewParamsData{
+        FirstName: stagehand.String("John"),
+    },
+}
+client.Foo.New(context.Background(), params, option.WithJSONSet("data.last_name", "Doe"))
+```
+
+#### Undocumented response properties
+
+To access undocumented response properties, you may either access the raw JSON of the response as a string
+with `result.JSON.RawJSON()`, or get the raw JSON of a particular field on the result with
+`result.JSON.Foo.Raw()`.
+
+Any fields that are not present on the response struct will be saved and can be accessed by `result.JSON.ExtraFields()` which returns the extra fields as a `map[string]Field`.
+
+### Middleware
+
+We provide `option.WithMiddleware` which applies the given
+middleware to requests.
+
+```go
+func Logger(req *http.Request, next option.MiddlewareNext) (res *http.Response, err error) {
+	// Before the request
+	start := time.Now()
+	LogReq(req)
+
+	// Forward the request to the next handler
+	res, err = next(req)
+
+	// Handle stuff after the request
+	end := time.Now()
+	LogRes(res, err, start - end)
+
+    return res, err
+}
+
+client := stagehand.NewClient(
+	option.WithMiddleware(Logger),
+)
+```
+
+When multiple middlewares are provided as variadic arguments, the middlewares
+are applied left to right. If `option.WithMiddleware` is given
+multiple times, for example first in the client then the method, the
+middleware in the client will run first and the middleware given in the method
+will run next.
+
+You may also replace the default `http.Client` with
+`option.WithHTTPClient(client)`. Only one http client is
+accepted (this overwrites any previous client) and receives requests after any
+middleware has been applied.
+
+## Semantic versioning
+
+This package generally follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions, though certain backwards-incompatible changes may be released as minor versions:
+
+1. Changes to library internals which are technically public but not intended or documented for external use. _(Please open a GitHub issue to let us know if you are relying on such internals.)_
+2. Changes that we do not expect to impact the vast majority of users in practice.
+
+We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.

+
+## What is Stagehand?
+
+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
+## Why Stagehand?
+
+Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language (and bridging the gap between the two) Stagehand is the natural choice for browser automations in production.
+
+1. **Choose when to write code vs. natural language**: use AI when you want to navigate unfamiliar pages, and use code when you know exactly what you want to do.
+
+2. **Go from AI-driven to repeatable workflows**: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.
+
+3. **Write once, run forever**: Stagehand's auto-caching combined with self-healing remembers previous actions, runs without LLM inference, and knows when to involve AI whenever the website changes and your automation breaks.
+
+## Installation
+
+### Gradle
+
+```java
+implementation("com.browserbase.api:stagehand-java:0.6.1")
+```
+
+### Maven
+
+```xml
+<dependency>
+  <groupId>com.browserbase.api</groupId>
+  <artifactId>stagehand-java</artifactId>
+  <version>0.6.1</version>
+</dependency>
+```
+
+## Requirements
+
+This library requires Java 8 through Java 21. Java 22+ is not currently supported.
+
+## Running the Example
+
+A complete working example is available at [`stagehand-java-example/src/main/java/com/stagehand/api/example/Main.java`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-example/src/main/java/com/stagehand/api/example/Main.java).
+
+To run it, first export the required environment variables, then use Gradle:
+
+```bash
+export BROWSERBASE_API_KEY="your-bb-api-key"
+export MODEL_API_KEY="sk-proj-your-llm-api-key"
+
+./gradlew :stagehand-java-example:run
+```
+
+## Usage
+
+This example demonstrates the full Stagehand workflow: starting a session, navigating to a page, observing possible actions, acting on elements, extracting data, and running an autonomous agent.
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+import com.browserbase.api.core.JsonValue;
+import com.browserbase.api.models.sessions.*;

+import java.util.List;
+import java.util.Map;
+import java.util.Optional;
+
+public class Main {
+    public static void main(String[] args) {
+        // Create client using environment variables:
+        // BROWSERBASE_API_KEY, MODEL_API_KEY
+        StagehandClient client = StagehandOkHttpClient.fromEnv();
+
+        // Start a new browser session
+        SessionStartResponse startResponse = client.sessions().start(
+            SessionStartParams.builder()
+                .modelName("openai/gpt-5-nano")
+                .build()

+
+        String sessionId = startResponse.data().sessionId();
+        System.out.println("Session started: " + sessionId);
+
+        try {

+
+            // Take the first action returned by Observe
+            // Convert the result to an Action to pass to Act
+            SessionObserveResponse.Data.Result result = results.get(0);

+            );
+            System.out.println("Session ended");
+        }
+    }
+}
+```
+
+## Client configuration
+
+Configure the client using system properties or environment variables:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+
+// Configures using the `stagehand.browserbaseApiKey`, `stagehand.modelApiKey` and `stagehand.baseUrl` system properties
+// Or configures using the `BROWSERBASE_API_KEY`, `MODEL_API_KEY` and `STAGEHAND_API_URL` environment variables
+StagehandClient client = StagehandOkHttpClient.fromEnv();
+```
+
+Or manually:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+
+StagehandClient client = StagehandOkHttpClient.builder()
+    .browserbaseApiKey("My Browserbase API Key")
+    .modelApiKey("My Model API Key")
+    .build();
+```
+
+Or using a combination of the two approaches:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+
+StagehandClient client = StagehandOkHttpClient.builder()
+    // Configures using the `stagehand.browserbaseApiKey`, `stagehand.modelApiKey` and `stagehand.baseUrl` system properties
+    // Or configures using the `BROWSERBASE_API_KEY`, `MODEL_API_KEY` and `STAGEHAND_API_URL` environment variables
+    .fromEnv()
+    .browserbaseApiKey("My Browserbase API Key")
+    .build();
+```
+
+See this table for the available options:
+
+| Setter                 | System property                  | Environment variable     | Required | Default value                             |
+| ---------------------- | -------------------------------- | ------------------------ | -------- | ----------------------------------------- |
+| `browserbaseApiKey`    | `stagehand.browserbaseApiKey`    | `BROWSERBASE_API_KEY`    | true     | -                                         |
+| `modelApiKey`          | `stagehand.modelApiKey`          | `MODEL_API_KEY`          | true     | -                                         |
+| `baseUrl`              | `stagehand.baseUrl`              | `STAGEHAND_API_URL`      | true     | `"https://api.stagehand.browserbase.com"` |
+
+System properties take precedence over environment variables.
+
+> [!TIP]
+> Don't create more than one client in the same application. Each client has a connection pool and
+> thread pools, which are more efficient to share between requests.
+
+### Modifying configuration
+
+To temporarily use a modified client configuration, while reusing the same connection and thread pools, call `withOptions()` on any client or service:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+
+StagehandClient clientWithOptions = client.withOptions(optionsBuilder -> {
+    optionsBuilder.modelApiKey("sk-your-llm-api-key-here");
+    optionsBuilder.maxRetries(42);
+});
+```
+
+The `withOptions()` method does not affect the original client or service.
+
+## Requests and responses
+
+To send a request to the Stagehand API, build an instance of some `Params` class and pass it to the corresponding client method. When the response is received, it will be deserialized into an instance of a Java class.
+
+For example, `client.sessions().act(...)` should be called with an instance of `SessionActParams`, and it will return an instance of `SessionActResponse`.
+
+## Immutability
+
+Each class in the SDK has an associated [builder](https://blogs.oracle.com/javamagazine/post/exploring-joshua-blochs-builder-design-pattern-in-java) or factory method for constructing it.
+
+Each class is [immutable](https://docs.oracle.com/javase/tutorial/essential/concurrency/immutable.html) once constructed. If the class has an associated builder, then it has a `toBuilder()` method, which can be used to convert it back to a builder for making a modified copy.
+
+Because each class is immutable, builder modification will _never_ affect already built class instances.
+
+## Asynchronous execution
+
+The default client is synchronous. To switch to asynchronous execution, call the `async()` method:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+import com.browserbase.api.models.sessions.SessionActParams;
+import com.browserbase.api.models.sessions.SessionActResponse;
+import java.util.concurrent.CompletableFuture;
+
+// Configures using the `stagehand.browserbaseApiKey`, `stagehand.modelApiKey` and `stagehand.baseUrl` system properties
+// Or configures using the `BROWSERBASE_API_KEY`, `MODEL_API_KEY` and `STAGEHAND_API_URL` environment variables
+StagehandClient client = StagehandOkHttpClient.fromEnv();
+
+SessionActParams params = SessionActParams.builder()
+    .id("00000000-your-session-id-000000000000")
+    .input("click the first link on the page")
+    .build();
+CompletableFuture<SessionActResponse> response = client.async().sessions().act(params);
+```
+
+Or create an asynchronous client from the beginning:
+
+```java
+import com.browserbase.api.client.StagehandClientAsync;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClientAsync;
+import com.browserbase.api.models.sessions.SessionActParams;
+import com.browserbase.api.models.sessions.SessionActResponse;
+import java.util.concurrent.CompletableFuture;
+
+// Configures using the `stagehand.browserbaseApiKey`, `stagehand.modelApiKey` and `stagehand.baseUrl` system properties
+// Or configures using the `BROWSERBASE_API_KEY`, `MODEL_API_KEY` and `STAGEHAND_API_URL` environment variables
+StagehandClientAsync client = StagehandOkHttpClientAsync.fromEnv();
+
+SessionActParams params = SessionActParams.builder()
+    .id("00000000-your-session-id-000000000000")
+    .input("click the first link on the page")
+    .build();
+CompletableFuture<SessionActResponse> response = client.sessions().act(params);
+```
+
+The asynchronous client supports the same options as the synchronous one, except most methods return `CompletableFuture`s.

+The SDK defines methods that return response "chunk" streams, where each chunk can be individually processed as soon as it arrives instead of waiting on the full response. Streaming methods generally correspond to [SSE](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events) or [JSONL](https://jsonlines.org) responses.
+
+Some of these methods may have streaming and non-streaming variants, but a streaming method will always have a `Streaming` suffix in its name, even if it doesn't have a non-streaming variant.
+
+These streaming methods return [`StreamResponse`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/core/http/StreamResponse.kt) for synchronous clients:
+
+```java
+import com.browserbase.api.core.http.StreamResponse;
+import com.browserbase.api.models.sessions.StreamEvent;
+
+try (StreamResponse<StreamEvent> streamResponse = client.sessions().actStreaming(params)) {
+    streamResponse.stream().forEach(chunk -> {
+        System.out.println(chunk);
+    });
+    System.out.println("No more chunks!");
+}
+```
+
+Or [`AsyncStreamResponse`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/core/http/AsyncStreamResponse.kt) for asynchronous clients:
+
+```java
+import com.browserbase.api.core.http.AsyncStreamResponse;
+import com.browserbase.api.models.sessions.StreamEvent;
+import java.util.Optional;
+
+client.async().sessions().actStreaming(params).subscribe(chunk -> {
+    System.out.println(chunk);
+});
+
+// If you need to handle errors or completion of the stream
+client.async().sessions().actStreaming(params).subscribe(new AsyncStreamResponse.Handler<>() {
+    @Override
+    public void onNext(StreamEvent chunk) {
+        System.out.println(chunk);
+    }
+
+    @Override
+    public void onComplete(Optional<Throwable> error) {
+        if (error.isPresent()) {
+            System.out.println("Something went wrong!");
+            throw new RuntimeException(error.get());
+        } else {
+            System.out.println("No more chunks!");
+        }
+    }
+});
+
+// Or use futures
+client.async().sessions().actStreaming(params)
+    .subscribe(chunk -> {
+        System.out.println(chunk);
+    })
+    .onCompleteFuture();
+    .whenComplete((unused, error) -> {
+        if (error != null) {
+            System.out.println("Something went wrong!");
+            throw new RuntimeException(error);
+        } else {
+            System.out.println("No more chunks!");
+        }
+    });
+```
+
+Async streaming uses a dedicated per-client cached thread pool [`Executor`](https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/Executor.html) to stream without blocking the current thread. This default is suitable for most purposes.
+
+To use a different `Executor`, configure the subscription using the `executor` parameter:
+
+```java
+import java.util.concurrent.Executor;
+import java.util.concurrent.Executors;
+
+Executor executor = Executors.newFixedThreadPool(4);
+client.async().sessions().actStreaming(params).subscribe(
+    chunk -> System.out.println(chunk), executor
+);
+```
+
+Or configure the client globally using the `streamHandlerExecutor` method:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+import java.util.concurrent.Executors;
+
+StagehandClient client = StagehandOkHttpClient.builder()
+    .fromEnv()
+    .streamHandlerExecutor(Executors.newFixedThreadPool(4))
+    .build();
+```
+
+## Raw responses
+
+The SDK defines methods that deserialize responses into instances of Java classes. However, these methods don't provide access to the response headers, status code, or the raw response body.
+
+To access this data, prefix any HTTP method call on a client or service with `withRawResponse()`:
+
+```java
+import com.browserbase.api.core.http.Headers;
+import com.browserbase.api.core.http.HttpResponseFor;
+import com.browserbase.api.models.sessions.SessionStartParams;
+import com.browserbase.api.models.sessions.SessionStartResponse;
+
+SessionStartParams params = SessionStartParams.builder()
+    .modelName("openai/gpt-5-nano")
+    .build();
+HttpResponseFor<SessionStartResponse> response = client.sessions().withRawResponse().start(params);
+
+int statusCode = response.statusCode();
+Headers headers = response.headers();
+```
+
+You can still deserialize the response into an instance of a Java class if needed:
+
+```java
+import com.browserbase.api.models.sessions.SessionStartResponse;
+
+SessionStartResponse parsedResponse = response.parse();
+```
+
+## Error handling
+
+The SDK throws custom unchecked exception types:
+
+- [`StagehandServiceException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/StagehandServiceException.kt): Base class for HTTP errors. See this table for which exception subclass is thrown for each HTTP status code:
+
+  | Status | Exception                                                                                                                          |
+  | ------ | ---------------------------------------------------------------------------------------------------------------------------------- |
+  | 400    | [`BadRequestException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/BadRequestException.kt)                     |
+  | 401    | [`UnauthorizedException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/UnauthorizedException.kt)                 |

+  | 404    | [`NotFoundException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/NotFoundException.kt)                         |
+  | 422    | [`UnprocessableEntityException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/UnprocessableEntityException.kt)   |
+  | 429    | [`RateLimitException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/RateLimitException.kt)                       |
+  | 5xx    | [`InternalServerException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/InternalServerException.kt)             |
+  | others | [`UnexpectedStatusCodeException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/UnexpectedStatusCodeException.kt) |
+
+  [`SseException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/SseException.kt) is thrown for errors encountered during [SSE streaming](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events) after a successful initial HTTP response.
+
+- [`StagehandIoException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/StagehandIoException.kt): I/O networking errors.
+
+- [`StagehandRetryableException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/StagehandRetryableException.kt): Generic error indicating a failure that could be retried by the client.
+
+- [`StagehandInvalidDataException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/StagehandInvalidDataException.kt): Failure to interpret successfully parsed data. For example, when accessing a property that's supposed to be required, but the API unexpectedly omitted it from the response.
+
+- [`StagehandException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/StagehandException.kt): Base class for all exceptions. Most errors will result in one of the previously mentioned ones, but completely generic errors may be thrown using the base class.
+
+## Logging
+
+The SDK uses the standard [OkHttp logging interceptor](https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor).
+
+Enable logging by setting the `STAGEHAND_LOG` environment variable to `info`:
+
+```sh
+export STAGEHAND_LOG=info
+```
+
+Or to `debug` for more verbose logging:
+
+```sh
+export STAGEHAND_LOG=debug
+```
+
+## ProGuard and R8
+
+Although the SDK uses reflection, it is still usable with [ProGuard](https://github.com/Guardsquare/proguard) and [R8](https://developer.android.com/topic/performance/app-optimization/enable-app-optimization) because `stagehand-java-core` is published with a [configuration file](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/resources/META-INF/proguard/stagehand-java-core.pro) containing [keep rules](https://www.guardsquare.com/manual/configuration/usage).
+
+ProGuard and R8 should automatically detect and use the published rules, but you can also manually copy the keep rules if necessary.
+
+## Jackson
+
+The SDK depends on [Jackson](https://github.com/FasterXML/jackson) for JSON serialization/deserialization. It is compatible with version 2.13.4 or higher, but depends on version 2.18.2 by default.
+
+The SDK throws an exception if it detects an incompatible Jackson version at runtime (e.g. if the default version was overridden in your Maven or Gradle config).
+
+If the SDK threw an exception, but you're _certain_ the version is compatible, then disable the version check using the `checkJacksonVersionCompatibility` on [`StagehandOkHttpClient`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClient.kt) or [`StagehandOkHttpClientAsync`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClientAsync.kt).
+
+> [!CAUTION]
+> We make no guarantee that the SDK works correctly when the Jackson version check is disabled.
+
+## Network options
+
+### Retries
+
+The SDK automatically retries 2 times by default, with a short exponential backoff between requests.
+
+Only the following error types are retried:
+
+- Connection errors (for example, due to a network connectivity problem)
+- 408 Request Timeout
+- 409 Conflict
+- 429 Rate Limit
+- 5xx Internal
+
+The API may also explicitly instruct the SDK to retry or not retry a request.
+
+To set a custom number of retries, configure the client using the `maxRetries` method:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+
+StagehandClient client = StagehandOkHttpClient.builder()
+    .fromEnv()
+    .maxRetries(4)
+    .build();
+```
+
+### Timeouts
+
+Requests time out after 1 minute by default.
+
+To set a custom timeout, configure the method call using the `timeout` method:
+
+```java
+import com.browserbase.api.models.sessions.SessionStartResponse;
+
+SessionStartResponse response = client.sessions().start(
+  params, RequestOptions.builder().timeout(Duration.ofSeconds(30)).build()
+);
+```
+
+Or configure the default for all method calls at the client level:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+import java.time.Duration;
+
+StagehandClient client = StagehandOkHttpClient.builder()
+    .fromEnv()
+    .timeout(Duration.ofSeconds(30))
+    .build();
+```
+
+### Proxies
+
+To route requests through a proxy, configure the client using the `proxy` method:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+import java.net.InetSocketAddress;
+import java.net.Proxy;
+
+StagehandClient client = StagehandOkHttpClient.builder()
+    .fromEnv()
+    .proxy(new Proxy(
+      Proxy.Type.HTTP, new InetSocketAddress(
+        "https://example.com", 8080
+      )
+    ))
+    .build();
+```
+
+### HTTPS
+
+> [!NOTE]
+> Most applications should not call these methods, and instead use the system defaults. The defaults include
+> special optimizations that can be lost if the implementations are modified.
+
+To configure how HTTPS connections are secured, configure the client using the `sslSocketFactory`, `trustManager`, and `hostnameVerifier` methods:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+
+StagehandClient client = StagehandOkHttpClient.builder()
+    .fromEnv()
+    // If `sslSocketFactory` is set, then `trustManager` must be set, and vice versa.
+    .sslSocketFactory(yourSSLSocketFactory)
+    .trustManager(yourTrustManager)
+    .hostnameVerifier(yourHostnameVerifier)
+    .build();
+```
+
+### Custom HTTP client
+
+The SDK consists of three artifacts:
+
+- `stagehand-java-core`
+  - Contains core SDK logic
+  - Does not depend on [OkHttp](https://square.github.io/okhttp)
+  - Exposes [`StagehandClient`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClient.kt), [`StagehandClientAsync`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientAsync.kt), [`StagehandClientImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientImpl.kt), and [`StagehandClientAsyncImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientAsyncImpl.kt), all of which can work with any HTTP client
+- `stagehand-java-client-okhttp`
+  - Depends on [OkHttp](https://square.github.io/okhttp)
+  - Exposes [`StagehandOkHttpClient`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClient.kt) and [`StagehandOkHttpClientAsync`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClientAsync.kt), which provide a way to construct [`StagehandClientImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientImpl.kt) and [`StagehandClientAsyncImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientAsyncImpl.kt), respectively, using OkHttp
+- `stagehand-java`
+  - Depends on and exposes the APIs of both `stagehand-java-core` and `stagehand-java-client-okhttp`
+  - Does not have its own logic
+
+This structure allows replacing the SDK's default HTTP client without pulling in unnecessary dependencies.
+
+#### Customized [`OkHttpClient`](https://square.github.io/okhttp/3.x/okhttp/okhttp3/OkHttpClient.html)
+
+> [!TIP]
+> Try the available [network options](#network-options) before replacing the default client.
+
+To use a customized `OkHttpClient`:
+
+1. Replace your [`stagehand-java` dependency](#installation) with `stagehand-java-core`
+2. Copy `stagehand-java-client-okhttp`'s [`OkHttpClient`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/OkHttpClient.kt) class into your code and customize it
+3. Construct [`StagehandClientImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientImpl.kt) or [`StagehandClientAsyncImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientAsyncImpl.kt), similarly to [`StagehandOkHttpClient`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClient.kt) or [`StagehandOkHttpClientAsync`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClientAsync.kt), using your customized client
+
+### Completely custom HTTP client
+
+To use a completely custom HTTP client:
+
+1. Replace your [`stagehand-java` dependency](#installation) with `stagehand-java-core`
+2. Write a class that implements the [`HttpClient`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/core/http/HttpClient.kt) interface
+3. Construct [`StagehandClientImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientImpl.kt) or [`StagehandClientAsyncImpl`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/client/StagehandClientAsyncImpl.kt), similarly to [`StagehandOkHttpClient`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClient.kt) or [`StagehandOkHttpClientAsync`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-client-okhttp/src/main/kotlin/com/browserbase/api/client/okhttp/StagehandOkHttpClientAsync.kt), using your new client class
+
+## Undocumented API functionality
+
+The SDK is typed for convenient usage of the documented API. However, it also supports working with undocumented or not yet supported parts of the API.
+
+### Parameters
+
+To set undocumented parameters, call the `putAdditionalHeader`, `putAdditionalQueryParam`, or `putAdditionalBodyProperty` methods on any `Params` class:
+
+```java
+import com.browserbase.api.core.JsonValue;
+import com.browserbase.api.models.sessions.SessionActParams;
+
+SessionActParams params = SessionActParams.builder()
+    .putAdditionalHeader("Secret-Header", "42")
+    .putAdditionalQueryParam("secret_query_param", "42")
+    .putAdditionalBodyProperty("secretProperty", JsonValue.from("42"))
+    .build();
+```
+
+These can be accessed on the built object later using the `_additionalHeaders()`, `_additionalQueryParams()`, and `_additionalBodyProperties()` methods.
+
+To set undocumented parameters on _nested_ headers, query params, or body classes, call the `putAdditionalProperty` method on the nested class:
+
+```java
+import com.browserbase.api.core.JsonValue;
+import com.browserbase.api.models.sessions.SessionActParams;
+
+SessionActParams params = SessionActParams.builder()
+    .options(SessionActParams.Options.builder()
+        .putAdditionalProperty("secretProperty", JsonValue.from("42"))
+        .build())
+    .build();
+```
+
+These properties can be accessed on the nested built object later using the `_additionalProperties()` method.
+
+To set a documented parameter or property to an undocumented or not yet supported _value_, pass a [`JsonValue`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/core/Values.kt) object to its setter:
+
+```java
+import com.browserbase.api.core.JsonValue;
+import com.browserbase.api.models.sessions.SessionActParams;
+
+SessionActParams params = SessionActParams.builder()
+    .input(JsonValue.from(42))
+    .build();
+```
+
+The most straightforward way to create a [`JsonValue`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/core/Values.kt) is using its `from(...)` method:
+
+```java
+import com.browserbase.api.core.JsonValue;
+import java.util.List;
+import java.util.Map;
+
+// Create primitive JSON values
+JsonValue nullValue = JsonValue.from(null);
+JsonValue booleanValue = JsonValue.from(true);
+JsonValue numberValue = JsonValue.from(42);
+JsonValue stringValue = JsonValue.from("Hello World!");
+
+// Create a JSON array value equivalent to `["Hello", "World"]`
+JsonValue arrayValue = JsonValue.from(List.of(
+  "Hello", "World"
+));
+
+// Create a JSON object value equivalent to `{ "a": 1, "b": 2 }`
+JsonValue objectValue = JsonValue.from(Map.of(
+  "a", 1,
+  "b", 2
+));
+
+// Create an arbitrarily nested JSON equivalent to:
+// {
+//   "a": [1, 2],
+//   "b": [3, 4]
+// }
+JsonValue complexValue = JsonValue.from(Map.of(
+  "a", List.of(
+    1, 2
+  ),
+  "b", List.of(
+    3, 4
+  )
+));
+```
+
+Normally a `Builder` class's `build` method will throw [`IllegalStateException`](https://docs.oracle.com/javase/8/docs/api/java/lang/IllegalStateException.html) if any required parameter or property is unset.
+
+To forcibly omit a required parameter or property, pass [`JsonMissing`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/core/Values.kt):
+
+```java
+import com.browserbase.api.core.JsonMissing;
+import com.browserbase.api.models.sessions.SessionActParams;
+
+SessionActParams params = SessionActParams.builder()
+    .input("Click the login button")
+    .id(JsonMissing.of())
+    .build();
+```
+
+### Response properties
+
+To access undocumented response properties, call the `_additionalProperties()` method:
+
+```java
+import com.browserbase.api.core.JsonValue;
+import java.util.Map;
+
+Map<String, JsonValue> additionalProperties = client.sessions().act(params)._additionalProperties();
+JsonValue secretPropertyValue = additionalProperties.get("secretProperty");
+
+String result = secretPropertyValue.accept(new JsonValue.Visitor<>() {
+    @Override
+    public String visitNull() {
+        return "It's null!";
+    }
+
+    @Override
+    public String visitBoolean(boolean value) {
+        return "It's a boolean!";
+    }
+
+    @Override
+    public String visitNumber(Number value) {
+        return "It's a number!";
+    }
+
+    // Other methods include `visitMissing`, `visitString`, `visitArray`, and `visitObject`
+    // The default implementation of each unimplemented method delegates to `visitDefault`, which throws by default, but can also be overridden
+});
+```
+
+To access a property's raw JSON value, which may be undocumented, call its `_` prefixed method:
+
+```java
+import com.browserbase.api.core.JsonField;
+import com.browserbase.api.models.sessions.SessionActParams;
+import java.util.Optional;
+
+JsonField<SessionActParams.Input> input = client.sessions().act(params)._input();
+
+if (input.isMissing()) {
+  // The property is absent from the JSON response
+} else if (input.isNull()) {
+  // The property was set to literal null
+} else {
+  // Check if value was provided as a string
+  // Other methods include `asNumber()`, `asBoolean()`, etc.
+  Optional<String> jsonString = input.asString();
+
+  // Try to deserialize into a custom type
+  MyClass myObject = input.asUnknown().orElseThrow().convert(MyClass.class);
+}
+```
+
+### Response validation
+
+In rare cases, the API may return a response that doesn't match the expected type. For example, the SDK may expect a property to contain a `String`, but the API could return something else.
+
+By default, the SDK will not throw an exception in this case. It will throw [`StagehandInvalidDataException`](https://github.com/browserbase/stagehand-java/blob/main/stagehand-java-core/src/main/kotlin/com/browserbase/api/errors/StagehandInvalidDataException.kt) only if you directly access the property.
+
+If you would prefer to check that the response is completely well-typed upfront, then either call `validate()`:
+
+```java
+import com.browserbase.api.models.sessions.SessionActResponse;
+
+SessionActResponse response = client.sessions().act(params).validate();
+```
+
+Or configure the method call to validate the response using the `responseValidation` method:
+
+```java
+import com.browserbase.api.models.sessions.SessionActResponse;
+
+SessionActResponse response = client.sessions().act(
+  params, RequestOptions.builder().responseValidation(true).build()
+);
+```
+
+Or configure the default for all method calls at the client level:
+
+```java
+import com.browserbase.api.client.StagehandClient;
+import com.browserbase.api.client.okhttp.StagehandOkHttpClient;
+

+## FAQ
+
+### Why don't you use plain `enum` classes?
+
+Java `enum` classes are not trivially [forwards compatible](https://www.stainless.com/blog/making-java-enums-forwards-compatible). Using them in the SDK could cause runtime exceptions if the API is updated to respond with a new enum value.
+
+### Why do you represent fields using `JsonField<T>` instead of just plain `T`?
+
+Using `JsonField<T>` enables a few features:
+
+- Allowing usage of [undocumented API functionality](#undocumented-api-functionality)
+- Lazily [validating the API response against the expected shape](#response-validation)
+- Representing absent vs explicitly null values
+
+### Why don't you use [`data` classes](https://kotlinlang.org/docs/data-classes.html)?
+
+It is not [backwards compatible to add new fields to a data class](https://kotlinlang.org/docs/api-guidelines-backward-compatibility.html#avoid-using-data-classes-in-your-api) and we don't want to introduce a breaking change every time we add a field to a class.
+
+### Why don't you use checked exceptions?
+
+Checked exceptions are widely considered a mistake in the Java programming language. In fact, they were omitted from Kotlin for this reason.
+
+Checked exceptions:
+
+- Are verbose to handle
+- Encourage error handling at the wrong level of abstraction, where nothing can be done about the error
+- Are tedious to propagate due to the [function coloring problem](https://journal.stuffwithstuff.com/2015/02/01/what-color-is-your-function)
+- Don't play well with lambdas (also due to the function coloring problem)
+
+## Semantic versioning
+
+This package generally follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions, though certain backwards-incompatible changes may be released as minor versions:
+
+1. Changes to library internals which are technically public but not intended or documented for external use. _(Please open a GitHub issue to let us know if you are relying on such internals.)_
+2. Changes that we do not expect to impact the vast majority of users in practice.
+
+We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.
+
+We are keen for your feedback; please open an [issue](https://www.github.com/browserbase/stagehand-java/issues) with questions, bugs, or suggestions.

+
+## What is Stagehand?
+
+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
+## Why Stagehand?
+
+Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language (and bridging the gap between the two) Stagehand is the natural choice for browser automations in production.
+
+1. **Choose when to write code vs. natural language**: use AI when you want to navigate unfamiliar pages, and use code when you know exactly what you want to do.
+
+2. **Go from AI-driven to repeatable workflows**: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.
+
+3. **Write once, run forever**: Stagehand's auto-caching combined with self-healing remembers previous actions, runs without LLM inference, and knows when to involve AI whenever the website changes and your automation breaks.
+
+## Installation
+
+```sh
+uv pip install stagehand
+```
+
+For local development or when working from this repository, sync the dependency lockfile with `uv` (see the Local development section below) before running project scripts.
+
+## Requirements
+
+Python 3.9 or higher.
+
+## Running the Example
+
+A complete working example is available at [`examples/full_example.py`](https://github.com/browserbase/stagehand-python/blob/main/examples/full_example.py).
+
+To run it, first export the required environment variables, then use Python:
+
+```bash
+export BROWSERBASE_API_KEY="your-bb-api-key"
+export MODEL_API_KEY="sk-proj-your-llm-api-key"
+
+uv run python examples/full_example.py
+```
+
+## Local mode example
+
+If you want to run Stagehand locally, use the local example (`examples/local_example.py`). It shows how to configure the client for `server="local"`.
+
+Local mode runs Stagehand’s embedded server and launches a **local Chrome/Chromium** browser (it is **not bundled** with the Python wheel), so you must have Chrome installed on the machine running the example.
+
+If Chrome is installed but Stagehand can’t find it, set `CHROME_PATH` to your browser executable (or pass `browser.launchOptions.executablePath` when starting the session).
+
+Common Windows paths:
+- `C:\Program Files\Google\Chrome\Application\chrome.exe`
+- `C:\Program Files (x86)\Google\Chrome\Application\chrome.exe`
+
+PowerShell:
+
+```powershell
+# optional if you don't already have Chrome installed
+winget install -e --id Google.Chrome
+
+# optional if Stagehand can't auto-detect Chrome
+$env:CHROME_PATH="C:\Program Files\Google\Chrome\Application\chrome.exe"
+
+uv run python examples/local_example.py
+```
+
+```bash
+uv pip install stagehand
+uv run python examples/local_example.py
+```
+
+## Streaming logging example
+
+See [`examples/logging_example.py`](https://github.com/browserbase/stagehand-python/blob/main/examples/logging_example.py) for a remote-only flow that streams `StreamEvent`s with `verbose=2`, `stream_response=True`, and `x_stream_response="true"` so you can watch the SDK’s logs as they arrive.
+
+```bash
+uv run python examples/logging_example.py
+```
+
+<details>
+<summary><strong>Local development</strong></summary>
+
+This repository relies on `uv` to install the sanctioned Python version and dependencies. After cloning, bootstrap the environment with:
+
+```sh
+./scripts/bootstrap
+```
+Once the environment is ready, execute repo scripts with `uv run`:
+
+```sh
+uv run python examples/full_example.py
+```
+</details>
+
+## Usage
+
+This example demonstrates the full Stagehand workflow: starting a session, navigating to a page, observing possible actions, acting on elements, extracting data, and running an autonomous agent.
+
+```python
+import asyncio
+
+from stagehand import AsyncStagehand
+
+async def main() -> None:
+    # Create client using environment variables:
+    # BROWSERBASE_API_KEY, MODEL_API_KEY
+    client = AsyncStagehand()
+
+    # Start a new browser session (returns a session helper bound to a session_id)
+    session = await client.sessions.create(model_name="openai/gpt-5-nano")
+
+    print(f"Session started: {session.id}")
+
+    try:
+        # Navigate to a webpage
+        await session.navigate(
+            url="https://news.ycombinator.com",
+        )
+        print("Navigated to Hacker News")
+
+        # Observe to find possible actions on the page
+        observe_response = await session.observe(
+            instruction="find the link to view comments for the top post",
+        )
+
+        results = observe_response.data.result
+        print(f"Found {len(results)} possible actions")
+        if not results:
+            return
+
+        # Take the first action returned by Observe and pass it to Act
+        action = results[0].to_dict(exclude_none=True)
+        print("Acting on:", action.get("description"))
+
+        act_response = await session.act(input=action)
+        print("Act completed:", act_response.data.result.message)
+
+        # Extract structured data from the page using a JSON schema
+        extract_response = await session.extract(
+            instruction="extract the text of the top comment on this page",
+            schema={
+                "type": "object",
+                "properties": {
+                    "commentText": {"type": "string"},
+                    "author": {"type": "string"},
+                },
+                "required": ["commentText"],
+            },
+        )
+
+        extracted = extract_response.data.result
+        author = extracted.get("author", "unknown") if isinstance(extracted, dict) else "unknown"
+        print("Extracted author:", author)
+
+        # Run an autonomous agent to accomplish a complex task
+        execute_response = await session.execute(
+            execute_options={
+                "instruction": f"Find any personal website, GitHub, or LinkedIn profile for the Hacker News user '{author}'.",
+                "max_steps": 10,
+            },
+            agent_config={"model": "openai/gpt-5-nano"},
+            timeout=300.0,
+        )
+
+        print("Agent completed:", execute_response.data.result.message)
+        print("Agent success:", execute_response.data.result.success)
+    finally:
+        # End the browser session to clean up resources
+        await session.end()
+        print("Session ended")
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+## Client configuration
+
+Configure the client using environment variables:
+
+```python
+from stagehand import AsyncStagehand
+
+client = AsyncStagehand()
+```
+
+Or manually:
+
+```python
+from stagehand import AsyncStagehand
+
+client = AsyncStagehand(
+    browserbase_api_key="My Browserbase API Key",
+    model_api_key="My Model API Key",
+)
+```
+
+Or using a combination of the two approaches:
+
+```python
+from stagehand import AsyncStagehand
+
+client = AsyncStagehand(
+    # Configures using environment variables
+    browserbase_api_key="My Browserbase API Key",  # override just this one
+)
+```
+
+See this table for the available options:
+
+| Keyword argument         | Environment variable     | Required | Default value                             |
+| ------------------------ | ------------------------ | -------- | ----------------------------------------- |
+| `browserbase_api_key`    | `BROWSERBASE_API_KEY`    | true     | -                                         |
+| `model_api_key`          | `MODEL_API_KEY`          | true     | -                                         |
+| `base_url`               | `STAGEHAND_API_URL`      | false    | `"https://api.stagehand.browserbase.com"` |
+
+Keyword arguments take precedence over environment variables.
+
+> [!TIP]
+> Don't create more than one client in the same application. Each client has a connection pool, which is more efficient to share between requests.
+
+### Modifying configuration
+
+To temporarily use a modified client configuration while reusing the same connection pool, call `with_options()` on any client:
+
+```python
+client_with_options = client.with_options(model_api_key="sk-your-llm-api-key-here", max_retries=42)
+```
+
+The `with_options()` method does not affect the original client.
+
+## Requests and responses
+
+To send a request to the Stagehand API, call the corresponding client method using keyword arguments.
+
+Nested request parameters are dictionaries typed using [`TypedDict`](https://docs.python.org/3/library/typing.html#typing.TypedDict). Responses are [Pydantic models](https://docs.pydantic.dev) which also provide helper methods like:
+
+- Serializing back into JSON: `model.to_json()`
+- Converting to a dictionary: `model.to_dict()`
+
+## Immutability
+
+Response objects are Pydantic models. If you want to build a modified copy, prefer `model.model_copy(update={...})` (Pydantic v2) rather than mutating in place.
+
+## Asynchronous execution
+
+This SDK recommends using `AsyncStagehand` and `await`ing each API call:
+
+```python
+import asyncio
+from stagehand import AsyncStagehand
+
+async def main() -> None:
+    client = AsyncStagehand()
+    session = await client.sessions.create(model_name="openai/gpt-5-nano")
+    response = await session.act(input="click the first link on the page")
+    print(response.data)
+
+asyncio.run(main())
+```
+
+### With aiohttp
+
+By default, the async client uses `httpx` for HTTP requests. For improved concurrency performance you may also use `aiohttp` as the HTTP backend.
+
+Install `aiohttp`:
+
+```sh
+uv run pip install stagehand[aiohttp]
+```
+
+Then instantiate the client with `http_client=DefaultAioHttpClient()`:
+
+```python
+import asyncio
+from stagehand import AsyncStagehand, DefaultAioHttpClient
+
+async def main() -> None:
+    async with AsyncStagehand(http_client=DefaultAioHttpClient()) as client:
+        session = await client.sessions.create(model_name="openai/gpt-5-nano")
+        response = await session.act(input="click the first link on the page")
+        print(response.data)
+
+asyncio.run(main())
+```
+
+## Streaming responses
+
+We provide support for streaming responses using Server-Sent Events (SSE).
+
+To enable SSE streaming, you must:
+
+1. Ask the server to stream by setting `x_stream_response="true"` (header), and
+2. Tell the client to parse an SSE stream by setting `stream_response=True`.
+
+```python
+import asyncio
+
+from stagehand import AsyncStagehand
+
+async def main() -> None:
+    async with AsyncStagehand() as client:
+        session = await client.sessions.create(model_name="openai/gpt-5-nano")
+
+        stream = await client.sessions.act(
+            id=session.id,
+            input="click the first link on the page",
+            stream_response=True,
+            x_stream_response="true",
+        )
+        async for event in stream:
+            # event is a StreamEvent (type: "system" | "log")
+            print(event.type, event.data)
+
+asyncio.run(main())
+```
+
+## Raw responses
+
+The SDK defines methods that deserialize responses into Pydantic models. However, these methods don't provide access to response headers, status code, or the raw response body.
+
+To access this data, prefix any HTTP method call on a client or service with `with_raw_response`:
+
+```python
+import asyncio
+
+from stagehand import AsyncStagehand
+
+async def main() -> None:
+    async with AsyncStagehand() as client:
+        response = await client.sessions.with_raw_response.start(model_name="openai/gpt-5-nano")
+        print(response.headers.get("X-My-Header"))
+
+        session = response.parse()  # get the object that `sessions.start()` would have returned
+        print(session.data)
+
+asyncio.run(main())
+```
+
+### `.with_streaming_response`
+
+The `with_raw_response` interface eagerly reads the full response body when you make the request.
+
+To stream the response body (not SSE), use `with_streaming_response` instead. It requires a context manager and only reads the response body once you call `.read()`, `.text()`, `.json()`, `.iter_bytes()`, `.iter_text()`, `.iter_lines()` or `.parse()`.
+
+```python
+import asyncio
+
+from stagehand import AsyncStagehand
+
+async def main() -> None:
+    async with AsyncStagehand() as client:
+        async with client.sessions.with_streaming_response.start(model_name="openai/gpt-5-nano") as response:
+            print(response.headers.get("X-My-Header"))
+            async for line in response.iter_lines():
+                print(line)
+
+asyncio.run(main())
+```
+
+## Error handling
+
+When the library is unable to connect to the API (for example, due to network connection problems or a timeout), a subclass of `stagehand.APIConnectionError` is raised.
+
+When the API returns a non-success status code (that is, 4xx or 5xx response), a subclass of `stagehand.APIStatusError` is raised, containing `status_code` and `response` properties.
+
+All errors inherit from `stagehand.APIError`.
+
+```python
+import asyncio
+
+import stagehand
+from stagehand import AsyncStagehand
+
+async def main() -> None:
+    async with AsyncStagehand() as client:
+        try:
+            await client.sessions.start(model_name="openai/gpt-5-nano")
+        except stagehand.APIConnectionError as e:
+            print("The server could not be reached")
+            print(e.__cause__)  # an underlying Exception, likely raised within httpx.
+        except stagehand.RateLimitError:
+            print("A 429 status code was received; we should back off a bit.")
+        except stagehand.APIStatusError as e:
+            print("A non-200-range status code was received")
+            print(e.status_code)
+            print(e.response)
+
+asyncio.run(main())
+```
+
+Error codes are as follows:
+
+| Status Code | Error Type                 |
+| ----------- | -------------------------- |
+| 400         | `BadRequestError`          |
+| 401         | `AuthenticationError`      |
+| 403         | `PermissionDeniedError`    |
+| 404         | `NotFoundError`            |
+| 422         | `UnprocessableEntityError` |
+| 429         | `RateLimitError`           |
+| >=500       | `InternalServerError`      |
+| N/A         | `APIConnectionError`       |
+
+### Retries
+
+Certain errors are automatically retried 2 times by default, with a short exponential backoff. Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict, 429 Rate Limit, and >=500 Internal errors are all retried by default.
+
+You can use the `max_retries` option to configure or disable retry settings:
+
+```python
+import asyncio
+
+from stagehand import AsyncStagehand
+
+async def main() -> None:
+    async with AsyncStagehand(max_retries=0) as client:
+        # Or, configure per-request:
+        await client.with_options(max_retries=5).sessions.start(model_name="openai/gpt-5-nano")
+
+asyncio.run(main())
+```
+
+### Timeouts
+
+By default requests time out after 1 minute. You can configure this with a `timeout` option, which accepts a float or an [`httpx.Timeout`](https://www.python-httpx.org/advanced/timeouts/#fine-tuning-the-configuration) object.
+
+On timeout, an `APITimeoutError` is thrown. Note that requests that time out are [retried twice by default](#retries).
+
+## Logging
+
+The SDK uses the standard library [`logging`](https://docs.python.org/3/library/logging.html) module.
+
+Enable logging by setting the `STAGEHAND_LOG` environment variable to `info`:
+
+```sh
+export STAGEHAND_LOG=info
+```
+
+Or to `debug` for more verbose logging:
+
+```sh
+export STAGEHAND_LOG=debug
+```
+
+## Undocumented API functionality
+
+This library is typed for convenient access to the documented API, but you can still access undocumented endpoints, request params, or response properties when needed.
+
+### Undocumented endpoints
+
+To make requests to undocumented endpoints, use `client.get`, `client.post`, and other HTTP verbs. Client options (such as retries) are respected.
+
+```python
+import httpx
+from stagehand import AsyncStagehand
+
+import asyncio
+
+async def main() -> None:
+    async with AsyncStagehand() as client:
+        response = await client.post("/foo", cast_to=httpx.Response, body={"my_param": True})
+        print(response.headers.get("x-foo"))
+
+asyncio.run(main())
+```
+
+### Undocumented request params
+
+To send extra params that aren't available as keyword args, use `extra_query`, `extra_body`, and `extra_headers`.
+
+### Undocumented response properties
+
+To access undocumented response properties, you can access extra fields like `response.unknown_prop`. You can also get all extra fields as a dict with [`response.model_extra`](https://docs.pydantic.dev/latest/api/base_model/#pydantic.BaseModel.model_extra).
+
+## Response validation
+
+In rare cases, the API may return a response that doesn't match the expected type.
+
+By default, the SDK is permissive and will only raise an error if you later try to use the invalid data.
+
+If you would prefer to validate responses upfront, instantiate the client with `_strict_response_validation=True`. An `APIResponseValidationError` will be raised if the API responds with invalid data for the expected schema.
+
+```python
+import asyncio
+
+from stagehand import APIResponseValidationError, AsyncStagehand
+
+try:
+    async def main() -> None:
+        async with AsyncStagehand(_strict_response_validation=True) as client:
+            await client.sessions.start(model_name="openai/gpt-5-nano")
+
+    asyncio.run(main())
+except APIResponseValidationError as e:
+    print("Response failed schema validation:", e)
+```
+
+## FAQ
+
+### Why are some values typed as `Literal[...]` instead of Python `Enum`s?
+
+Using `Literal[...]` types is forwards compatible: the API can introduce new enum values without breaking older SDKs at runtime.
+
+### How can I tell whether `None` means `null` or “missing” in a response?
+
+In an API response, a field may be explicitly `null`, or missing entirely; in either case its value is `None` in this library. You can differentiate the two cases with `.model_fields_set`:
+
+```python
+if response.my_field is None:
+    if "my_field" not in response.model_fields_set:
+        print('Got json like {}, without a "my_field" key present at all.')
+    else:
+        print('Got json like {"my_field": null}.')
+```
+
+## Semantic versioning
+
+This package generally follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions, though certain backwards-incompatible changes may be released as minor versions:
+
+1. Changes that only affect static types, without breaking runtime behavior.
+2. Changes to library internals which are technically public but not intended or documented for external use. _(Please open a GitHub issue to let us know if you are relying on such internals.)_
+3. Changes that we do not expect to impact the vast majority of users in practice.
+
+We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.
+
+We are keen for your feedback; please open an [issue](https://www.github.com/browserbase/stagehand-python/issues) with questions, bugs, or suggestions.
+
+### Determining the installed version
+
+If you've upgraded to the latest version but aren't seeing any new features you were expecting then your python environment is likely still using an older version.
+
+You can determine the version that is being used at runtime with:
+
+```python
+import stagehand
+
+print(stagehand.__version__)
+```

+Stagehand is a browser automation framework used to control web browsers with natural language and code. By combining the power of AI with the precision of code, Stagehand makes web automation flexible, maintainable, and actually reliable.
+
+## Why Stagehand?
+
+Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language (and bridging the gap between the two) Stagehand is the natural choice for browser automations in production.
+
+1. **Choose when to write code vs. natural language**: use AI when you want to navigate unfamiliar pages, and use code when you know exactly what you want to do.
+
+2. **Go from AI-driven to repeatable workflows**: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.
+
+3. **Write once, run forever**: Stagehand's auto-caching combined with self-healing remembers previous actions, runs without LLM inference, and knows when to involve AI whenever the website changes and your automation breaks.
+
+## Installation
+
+To use this gem, install via Bundler by adding the following to your application's `Gemfile`:
+
+```ruby
+gem "stagehand", "~> 0.6.2"
+```
+
+## Usage
+
+```ruby
+require "bundler/setup"
+require "stagehand"
+
+# Create a new Stagehand client with your credentials
+client = Stagehand::Client.new(
+  browserbase_api_key: ENV["BROWSERBASE_API_KEY"], # defaults to ENV["BROWSERBASE_API_KEY"]
+  model_api_key: ENV["MODEL_API_KEY"]              # defaults to ENV["MODEL_API_KEY"]
+)
+
+# Start a new browser session
+start_response = client.sessions.start(
+  model_name: "openai/gpt-5-nano"
+)
+puts "Session started: #{start_response.data.session_id}"
+
+session_id = start_response.data.session_id
+
+# Navigate to a webpage
+client.sessions.navigate(
+  session_id,
+  url: "https://news.ycombinator.com"
+)
+puts "Navigated to Hacker News"
+
+# Use Observe to find possible actions on the page
+observe_response = client.sessions.observe(
+  session_id,
+  instruction: "find the link to view comments for the top post"
+)
+
+actions = observe_response.data.result
+puts "Found #{actions.length} possible actions"
+
+# Take the first action returned by Observe
+action = actions.first
+puts "Acting on: #{action.description}"
+
+# Pass the structured action to Act
+# Convert the observe result to a hash and ensure method is set to "click"
+act_response = client.sessions.act(
+  session_id,
+  input: action.to_h.merge(method: "click")
+)
+puts "Act completed: #{act_response.data.result[:message]}"
+
+# Extract data from the page
+# We're now on the comments page, so extract the top comment text
+extract_response = client.sessions.extract(
+  session_id,
+  instruction: "extract the text of the top comment on this page",
+  schema: {
+    type: "object",
+    properties: {
+      comment_text: {
+        type: "string",
+        description: "The text content of the top comment"
+      },
+      author: {
+        type: "string",
+        description: "The username of the comment author"
+      }
+    },
+    required: ["comment_text"]
+  }
+)
+puts "Extracted data: #{extract_response.data.result}"
+
+# Get the author from the extracted data
+extracted_data = extract_response.data.result
+author = extracted_data[:author]
+puts "Looking up profile for author: #{author}"
+
+# Use the Agent to find the author's profile
+# Execute runs an autonomous agent that can navigate and interact with pages
+execute_response = client.sessions.execute(
+  session_id,
+  execute_options: {
+    instruction: "Find any personal website, GitHub, LinkedIn, or other best profile URL for the Hacker News user '#{author}'. " \
+                 "Click on their username to go to their profile page and look for any links they have shared.",
+    max_steps: 15
+  },
+  agent_config: {
+    model: Stagehand::ModelConfig::ModelConfigObject.new(
+      model_name: "openai/gpt-5-nano",
+      api_key: ENV["MODEL_API_KEY"]
+    ),
+    cua: false
+  }
+)
+puts "Agent completed: #{execute_response.data.result[:message]}"
+puts "Agent success: #{execute_response.data.result[:success]}"
+puts "Agent actions taken: #{execute_response.data.result[:actions]&.length || 0}"
+
+# End the session to cleanup browser resources
+client.sessions.end_(session_id)
+puts "Session ended"
+```
+
+### Running the Example
+
+Set the required environment variables and run the example script:
+
+```bash
+# Set your credentials
+export BROWSERBASE_API_KEY="your-browserbase-api-key"
+export MODEL_API_KEY="your-openai-api-key"
+
+# Install dependencies and run
+bundle install
+bundle exec ruby examples/basic.rb
+```
+
+### Streaming
+
+We provide support for streaming responses using Server-Sent Events (SSE).
+
+```ruby
+stream = stagehand.sessions.act_streaming(
+  "00000000-your-session-id-000000000000",
+  input: "click the first link on the page"
+)
+
+stream.each do |session|
+  puts(session.data)
+end
+```
+
+### Handling errors
+
+When the library is unable to connect to the API, or if the API returns a non-success status code (i.e., 4xx or 5xx response), a subclass of `Stagehand::Errors::APIError` will be thrown:
+
+```ruby
+begin
+  session = stagehand.sessions.start(model_name: "openai/gpt-5-nano")
+rescue Stagehand::Errors::APIConnectionError => e
+  puts("The server could not be reached")
+  puts(e.cause)  # an underlying Exception, likely raised within `net/http`
+rescue Stagehand::Errors::RateLimitError => e
+  puts("A 429 status code was received; we should back off a bit.")
+rescue Stagehand::Errors::APIStatusError => e
+  puts("Another non-200-range status code was received")
+  puts(e.status)
+end
+```
+
+Error codes are as follows:
+
+| Cause            | Error Type                 |
+| ---------------- | -------------------------- |
+| HTTP 400         | `BadRequestError`          |
+| HTTP 401         | `AuthenticationError`      |
+| HTTP 403         | `PermissionDeniedError`    |
+| HTTP 404         | `NotFoundError`            |
+| HTTP 409         | `ConflictError`            |
+| HTTP 422         | `UnprocessableEntityError` |
+| HTTP 429         | `RateLimitError`           |
+| HTTP >= 500      | `InternalServerError`      |
+| Other HTTP error | `APIStatusError`           |
+| Timeout          | `APITimeoutError`          |
+| Network error    | `APIConnectionError`       |
+
+### Retries
+
+Certain errors will be automatically retried 2 times by default, with a short exponential backoff.
+
+Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict, 429 Rate Limit, >=500 Internal errors, and timeouts will all be retried by default.
+
+You can use the `max_retries` option to configure or disable this:
+
+```ruby
+# Configure the default for all requests:
+stagehand = Stagehand::Client.new(
+  max_retries: 0 # default is 2
+)
+
+# Or, configure per-request:
+stagehand.sessions.start(model_name: "openai/gpt-5-nano", request_options: {max_retries: 5})
+```
+
+### Timeouts
+
+By default, requests will time out after 60 seconds. You can use the timeout option to configure or disable this:
+
+```ruby
+# Configure the default for all requests:
+stagehand = Stagehand::Client.new(
+  timeout: nil # default is 60
+)
+
+# Or, configure per-request:
+stagehand.sessions.start(model_name: "openai/gpt-5-nano", request_options: {timeout: 5})
+```
+
+On timeout, `Stagehand::Errors::APITimeoutError` is raised.
+
+Note that requests that time out are retried by default.
+
+## Advanced concepts
+
+### BaseModel
+
+All parameter and response objects inherit from `Stagehand::Internal::Type::BaseModel`, which provides several conveniences, including:
+
+1. All fields, including unknown ones, are accessible with `obj[:prop]` syntax, and can be destructured with `obj => {prop: prop}` or pattern-matching syntax.
+
+2. Structural equivalence for equality; if two API calls return the same values, comparing the responses with == will return true.
+
+3. Both instances and the classes themselves can be pretty-printed.
+
+4. Helpers such as `#to_h`, `#deep_to_h`, `#to_json`, and `#to_yaml`.
+
+### Making custom or undocumented requests
+
+#### Undocumented properties
+
+You can send undocumented parameters to any endpoint, and read undocumented response properties, like so:
+
+Note: the `extra_` parameters of the same name overrides the documented parameters.
+
+```ruby
+response =
+  stagehand.sessions.start(
+    model_name: "openai/gpt-5-nano",
+    request_options: {
+      extra_query: {my_query_parameter: value},
+      extra_body: {my_body_parameter: value},
+      extra_headers: {"my-header": value}
+    }
+  )
+
+puts(response[:my_undocumented_property])
+```
+
+#### Undocumented request params
+
+If you want to explicitly send an extra param, you can do so with the `extra_query`, `extra_body`, and `extra_headers` under the `request_options:` parameter when making a request, as seen in the examples above.
+
+#### Undocumented endpoints
+
+To make requests to undocumented endpoints while retaining the benefit of auth, retries, and so on, you can make requests using `client.request`, like so:
+
+```ruby
+response = client.request(
+  method: :post,
+  path: '/undocumented/endpoint',
+  query: {"dog": "woof"},
+  headers: {"useful-header": "interesting-value"},
+  body: {"hello": "world"}
+)
+```
+
+### Concurrency & connection pooling
+
+The `Stagehand::Client` instances are threadsafe, but are only are fork-safe when there are no in-flight HTTP requests.
+
+Each instance of `Stagehand::Client` has its own HTTP connection pool with a default size of 99. As such, we recommend instantiating the client once per application in most settings.
+
+When all available connections from the pool are checked out, requests wait for a new connection to become available, with queue time counting towards the request timeout.
+
+Unless otherwise specified, other classes in the SDK do not have locks protecting their underlying data structure.
+
+## Sorbet
+
+This library provides comprehensive [RBI](https://sorbet.org/docs/rbi) definitions, and has no dependency on sorbet-runtime.
+
+You can provide typesafe request parameters like so:
+
+```ruby
+stagehand.sessions.act("00000000-your-session-id-000000000000", input: "click the first link on the page")
+```
+
+Or, equivalently:
+
+```ruby
+# Hashes work, but are not typesafe:
+stagehand.sessions.act("00000000-your-session-id-000000000000", input: "click the first link on the page")
+
+# You can also splat a full Params class:
+params = Stagehand::SessionActParams.new(input: "click the first link on the page")
+stagehand.sessions.act("00000000-your-session-id-000000000000", **params)
+```
+
+### Enums
+
+Since this library does not depend on `sorbet-runtime`, it cannot provide [`T::Enum`](https://sorbet.org/docs/tenum) instances. Instead, we provide "tagged symbols" instead, which is always a primitive at runtime:
+
+```ruby
+# :typescript
+puts(Stagehand::SessionActParams::XLanguage::TYPESCRIPT)
+
+# Revealed type: `T.all(Stagehand::SessionActParams::XLanguage, Symbol)`
+T.reveal_type(Stagehand::SessionActParams::XLanguage::TYPESCRIPT)
+```
+
+Enum parameters have a "relaxed" type, so you can either pass in enum constants or their literal value:
+
+```ruby
+# Using the enum constants preserves the tagged type information:
+stagehand.sessions.act(
+  x_language: Stagehand::SessionActParams::XLanguage::TYPESCRIPT,
+  # …
+)
+
+# Literal values are also permissible:
+stagehand.sessions.act(
+  x_language: :typescript,
+  # …
+)
+```
+
+## Versioning
+
+This package follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions. As the library is in initial development and has a major version of `0`, APIs may change at any time.
+
+This package considers improvements to the (non-runtime) `*.rbi` and `*.rbs` type definitions to be non-breaking changes.
+
+## Requirements
+
+Ruby 3.2.0 or higher.

+# Stagehand Evals
+
+Agent benchmarks for Stagehand — `act`, `extract`, `observe`, `agent`, `combination`, plus dataset-backed suites (WebVoyager, OnlineMind2Web, WebTailBench, GAIA).
+
+Driven by an interactive TUI (`evals`) or single-shot CLI (`evals run …`). Tasks are auto-discovered from `tasks/bench/<category>/` — no registration step.
+
+
+## Quickstart
+
+From the stagehand repo root:
+
+```bash
+pnpm install
+pnpm build:cli   # also: pnpm build, if you haven't built the workspace yet
+```
+
+This links an `evals` binary on your `PATH`. Launch the REPL:
+
+```bash
+evals
+```
+
+![REPL with help output](./assets/readme/help.png)
+
+Or run a single target:
+
+```bash
+evals run extract -t 3 -c 5
+evals run b:webvoyager -l 10
+```
+
+A `.env` in `packages/evals/` is loaded automatically. Provide whichever provider keys (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GOOGLE_GENERATIVE_AI_API_KEY`, …) and `BROWSERBASE_API_KEY` / `BROWSERBASE_PROJECT_ID` you need.
+
+## TUI commands
+
+Inside the REPL (or as `evals <command>` from your shell):
+
+| Command | What it does |
+| --- | --- |
+| `run [target] [options]` | Run evals. Target can be a tier, category, task, or benchmark shorthand. |
+| `list [tier] [--detailed]` | List discovered tasks and categories. |
+| `new <tier> <category> <name>` | Scaffold a new task file. |
+| `config [set\|reset\|path]` | Read or write defaults (env, trials, concurrency, model, …). |
+| `experiments` | Inspect and compare Braintrust experiment runs. |
+| `help` | Show command help. Append `--help` to any command for details. |
+
+Use `Esc` to abort an in-flight run without exiting the REPL.
+
+## Run targets
+
+`evals run` accepts any of these shapes:
+
+| Target | Meaning |
+| --- | --- |
+| _(none)_ / `all` | All bench tasks |
+| `bench` | Entire bench tier |
+| `act` / `extract` / `observe` / `agent` / `combination` | A category |
+| `extract/extract_text` | A specific task |
+| `b:webvoyager` / `b:onlineMind2Web` / `b:webtailbench` | Dataset-backed benchmark suite |
+
+`evals list` shows everything that's been discovered:
+
+![evals list output](./assets/readme/list.png)
+
+## Common options
+
+| Flag | Purpose |
+| --- | --- |
+| `-e, --env <local\|browserbase>` | Where the browser runs |
+| `-t, --trials <n>` | Trials per task |
+| `-c, --concurrency <n>` | Max parallel sessions |
+| `-m, --model <id>` / `-p, --provider <name>` | Override the model/provider matrix |
+| `--api` | Run via the Stagehand API instead of the SDK |
+| `--harness <stagehand\|claude_code\|codex>` | Which agent harness drives the bench task |
+| `--agent-mode <dom\|hybrid\|cua>` / `--agent-modes <csv>` | Stagehand agent mode (or matrix) |
+| `-l, --limit <n>` / `-s, --sample <n>` / `-f, --filter key=value` | Suite shaping for benchmark targets |
+| `--preview` | Print the resolved plan and exit — no browser, no LLM calls |
+
+Defaults live in `evals.config.json` and can be edited via `evals config set …`.
+
+`--preview` is useful for sanity-checking the plan before paying for a run:
+
+![evals run --preview output](./assets/readme/preview.png)
+
+A live run paints an in-place progress table, then prints a final summary with a per-model breakdown:
+
+![Live bench run](./assets/readme/run.gif)
+
+## Adding a bench task
+
+```bash
+evals new bench extract my_new_task
+```
+
+This drops a `defineBenchTask`-based file into `tasks/bench/extract/`. It will show up in `evals list` on next launch — no config edit needed.
+
+```ts
+// tasks/bench/extract/my_new_task.ts
+import { defineBenchTask } from "../../../framework/defineTask.js";
+
+export default defineBenchTask({
+  name: "my_new_task",
+  tags: ["regression"],
+  run: async ({ stagehand, logger }) => {
+    // ... drive stagehand, return { _success: boolean, ... }
+  },
+});
+```
+
+## Tracing / Observability
+
+Runs stream into Braintrust when `BRAINTRUST_API_KEY` is set; otherwise a local summary prints to stdout. Use `evals experiments` to inspect and diff past Braintrust runs.

Once you’ve got that baseline, stay on Booking.com and look up NOX Hotel for a 1-night stay for 2 adults on any date in 2026, just so I can tell whether my bargain London option is unusually cheap or more normal for the city; open the NOX listing page too and record the date and total displayed price you find. After that, use Google to look for at least two hotels near Washington, DC Union Station that show 4-star-or-higher guest ratings and nightly prices under $200, because I may want a backup benchmark for city lodging in another trip later; please open each hotel result in its own tab or go to the actual hotel posting page so I can verify they’re real options and still look live. Then, because I want the whole trip to stay low-cost overall, go to Amazon and shortlist three mid-to-low-priced headphones or earbuds with active noise cancellation for travel that fit the same budget mindset, and open each product page in a separate tab so I can compare them side by side. In the end, send me one clean summary with the hotel names, prices, dates, ratings where relevant, key headphone features, and links, and leave the Booking.com property tabs and the Amazon product tabs open for me.","website":"https://www.google.com","level":"medium","reference_length":5,"categories":["Travel and Tourism > Air Travel","Travel and Tourism > Accommodation and Hotels"],"precomputed_rubric":{"items":[{"criterion":"Identify at least one Booking.com London hotel for 2 adults in December with a displayed total price under £100 for the 2-night stay, and capture the hotel name, stay dates, total price, and link.","description":"Identify at least one Booking.com London hotel for 2 adults in December with a displayed total price under £100 for the 2-night stay, and capture the hotel name, stay dates, total price, and link.\n\nHow a grader verifies this: Grader can confirm the Booking.com search results or property page shows London, 2 adults December and a total under £100, with the property tab open.","max_points":280},{"criterion":"Find a Booking.com NOX Hotel result for a 1-night stay in 2026 for 2 adults and record the specific date, displayed total price, and link.","description":"Find a Booking.com NOX Hotel result for a 1-night stay in 2026 for 2 adults and record the specific date, displayed total price, and link.\n\nHow a grader verifies this: Grader can confirm the NOX Hotel listing or property page on Booking.com shows a 1-night stay for 2 adults with a visible total price and the page left open.","max_points":200},{"criterion":"Find at least two hotels near Washington, DC Union Station via Google that each show a guest rating of 4 stars or higher and a nightly price under $200, and record their names, ratings, prices, and links.","description":"Find at least two hotels near Washington, DC Union Station via Google that each show a guest rating of 4 stars or higher and a nightly price under $200, and record their names, ratings, prices, and links.\n\nHow a grader verifies this: Grader can confirm on Google results, hotel panels, or linked hotel pages that two qualifying hotels near Union Station display ratings of 4.0+ and nightly prices below $200, with tabs open for the chosen options.","max_points":220},{"criterion":"Shortlist at least three Amazon headphones or earbuds with active noise cancellation, including each product name, current price, key features, and link.","description":"Shortlist at least three Amazon headphones or earbuds with active noise cancellation, including each product name, current price, key features, and link.\n\nHow a grader verifies this: Grader can confirm three Amazon product pages are open and each page visibly indicates ANC or active noise cancellation, along with product name and current price.","max_points":180},{"criterion":"Return one consolidated summary covering the London budget hotel, the NOX Hotel comparison, the two Washington, DC Union Station hotel benchmarks, and the three Amazon UK headphone options, with all requested names, dates, prices, ratings where relevant, key features, and links.","description":"Return one consolidated summary covering the London budget hotel, the NOX Hotel comparison, the two Washington, DC Union Station hotel benchmarks, and the three Amazon UK headphone options, with all requested names, dates, prices, ratings where relevant, key features, and links.\n\nHow a grader verifies this: Grader can compare the final response against the collected browser evidence from the open Booking.com, Google, and Amazon UK tabs and verify all requested fields are included.","max_points":120}]}}

Then use Google Images to find one cartoon mouse image with a transparent background that could work as a reference asset, and open the actual source page plus the direct image in separate tabs so I can visually confirm it really has transparency and isn’t just a white background baked in. While you’re in Google Images, also search for “taffy tails stretchy” and pick one result for Stretchy from Taffy Tails, opening the result page too so I can compare whether I want a generic mouse look or that more specific character style. After that, go to react-svgr.com and convert a simple SVG into a React component so I have a vector element to pair with the raster mouse image in the prototype, and keep the conversion result visible. Once the visual side is sorted out, use Google to find the current guidance on whether a project made in CapCut Web can be moved into the CapCut desktop app, because I may reuse these same art assets in a promo clip later, and then find instructions for changing the background color behind an imported photo in CapCut so the background can match whichever mouse style looked better from the earlier image search.

Please start by opening CryptPad Sheets and create a spreadsheet called \"CS Faculty Job Search\" with columns for university, department or school, job title, area, rank, deadline, posting link, and a short verification note, because I want a clean tracker I can review later. Then use CSRankings to pull the top 50 U.S. CS schools and keep that page open as the master checklist so I can see exactly which schools were covered.

If you find a relevant opening, open the actual posting page in its own tab and read it directly rather than relying on search snippets, and if you had to use a department hiring page or university careers page to confirm it, leave that verification page open too so I can inspect the trail myself. If a school seems to have no relevant opening, I still want you to verify that as carefully as possible from the department or university hiring information before moving on, because the absence is useful too.

Once you've got both flight options, pull up Google Maps and check the drive time from LAX to Palm Springs, because I only want to drive between 9am and 4pm — so if the LAX flight lands too late to make that window, either adjust the flight date or find me a hotel near LAX on Booking.com for an overnight stay before driving, and leave the hotel page open so I can see the price and location. If PSP ends up being the better option and skips the drive issue entirely, flag that clearly. After that, search for car rental options at whichever airport makes more sense for the dates I'd need, and open at least one rental listing so I can see the vehicle type and daily rate. Then check whether I could squeeze in a stop at either Soban or Holbox on any of the drives between the airport and Palm Springs — look up both on Google Maps, see how far each detour would add, and recommend which one is actually worth it given the 9am–4pm driving constraint.

Once those are open, go to U-Haul and price out a one-way 15-foot truck from Pittsburgh to San Francisco, then on U-Haul’s site find the MPG or fuel economy info for that truck so we can estimate the real driving cost. Use Google Maps to pull up the driving route from Pittsburgh, PA to San Francisco, CA and record the mileage, and leave the map visible so I can sanity-check the route distance on screen. I also have State Farm renters insurance, so please look on State Farm’s site to see whether my belongings are covered while they’re in transit during a move or whether I’d probably need separate moving coverage or valuation.

Then use maps and hotel photo pages to sanity-check the arrival setup for each place — things like whether the entrance and garage situation look straightforward, whether it seems attached or off-site, and how walkable the hotel is to at least 3 downtown anchors: Market Square, PPG Paints Arena, and PNC Park. After that, compare the 8 hotels on driver convenience and likely all-in nightly cost, using one sample future 2-night stay price from a public booking flow or listing page for each hotel when available, and make me a ranked top-5 shortlist for a driver who wants a nice stay without getting killed on parking or ending up with awkward car logistics.

Once you have that, use the official Canadian embassy/consulate pages to figure out which Canadian mission is closest to Pittsburgh, Pennsylvania 15222 that handles passport services, and open the actual office page so I can see the address, passport service hours, and whether I need an appointment or have to use some booking request process; please leave that page open. After that, check Japan’s official Ministry of Foreign Affairs site to confirm whether a Canadian passport holder going to Japan for tourism for 2 weeks needs a visa, and note any conditions or exceptions that matter. Then go to the Government of Canada travel advisory page for Japan and tell me the current advisory level plus any highlighted health, safety, or entry notes, and keep that advisory page open in another tab so I can look at it myself. Finally, compare travel insurance options on PolicyAdvisor.com and Kanetix.ca for this situation: a Canadian citizen currently living in the U.S. who wants coverage connected to travel to Japan, and I mainly want to see whether either site shows plans that would actually work for someone based in the U.S. rather than Canada, so please capture provider names, medical emergency coverage, trip cancellation/interruption if shown, and any residency or eligibility restrictions. If either site has useful quote or results pages, open the most relevant options in separate tabs so I can compare them visually. At the end, give me a concise summary that ties all of this together and clearly points out any uncertainty, especially around insurance eligibility for a Canadian living in the U.S.",

Once you’ve got both sets, compare the six options, remove duplicates if the same property shows up on both sites, and tell me which apartments seem like the best overall fit based on price, amenities, and location near the Domain. After that, use CapMetro’s site and map tools to check whether each shortlisted apartment is near a MetroRail stop or has a practical bus connection into the Domain area, because I want to know whether I could commute without driving every day; if the map view helps, pull it up and keep the most useful transit page open. Then look up the neighborhoods for those apartments on Niche so I can get a feel for what living there would be like, especially safety ratings, walkability info if it’s shown, and whether there are grocery stores nearby for basic errands. Finally, go to the Texas Attorney General website and find the renters’ rights guidance that matters most before signing a lease in Texas, especially anything about deposits, repairs, fees, disclosures, and ending a lease, and leave that page open too so I can read it myself later. In the end, give me one clean apartment-hunting brief that combines the listing comparison, transit practicality to the Domain, neighborhood pros and cons, and a short lease-review checklist I can use when I start contacting properties.",

Start on Booking.com and search London for 2 adults staying this December, then find me at least one hotel that comes in under £100 total for the 2-night stay, because that ultra-budget option is going to set the tone for everything else. Open the actual property page in its own tab so I can see the photos and location, and note the hotel name, stay dates, total displayed price, and link. Once you’ve got that baseline, stay on Booking.com and look up NOX Hotel for a 1-night stay for 2 adults on any date in 2026, just so I can tell whether my bargain London option is unusually cheap or more normal for the city; open the NOX listing page too and record the date and total displayed price you find. After that, use Google to look for at least two hotels near Washington, DC Union Station that show 4-star-or-higher guest ratings and nightly prices under $200, because I may want a backup benchmark for city lodging in another trip later; please open each hotel result in its own tab or go to the actual hotel posting page so I can verify they’re real options and still look live. Then, because I want the whole trip to stay low-cost overall, go to Amazon and shortlist three mid-to-low-priced headphones or earbuds with active noise cancellation for travel that fit the same budget mindset, and open each product page in a separate tab so I can compare them side by side. In the end, send me one clean summary with the hotel names, prices, dates, ratings where relevant, key headphone features, and links, and leave the Booking.com property tabs and the Amazon product tabs open for me.",

Open the actual template page and leave it open so I can see the preview images, and note whether it’s available for Google Slides or PowerPoint. Then use Google to find a printable worksheet or practice page for an 8th-grade student on basic marketing strategies or persuasion techniques, like identifying advertising tricks or persuasive techniques, and open the actual resource page so I can check that it really looks classroom-ready and printable. After that, go to Citation Machine and verify that Harvard style is actually available there by navigating to wherever the citation styles are shown or selectable, because I’ll need to cite the worksheet and any media correctly; leave that proof visible or keep the page open. Finally, on YouTube, find three beginner-friendly videos about online safety or cybersecurity basics that would make sense for students, open each video in its own tab so I can compare them, and play one of them briefly so you can tell me what the opening covers. At the end, send me a short lesson-pack summary with the Slidesgo template name and format option, the worksheet title and where it’s hosted, the evidence that Harvard style can be selected on the citation site, and the three YouTube video titles with their channel names.",

Start on Depop and go to the seller page for rainbow_bebe to see whether they currently have any prom dress listings under $100, because if there’s a good one there I’d use that as my budget anchor; open at least one qualifying listing in its own tab so I can see the actual photos and price on the live listing page. If that seller doesn’t have a convincing under-$100 option, switch to PrettyLittleThing and find an emerald green dress that’s available in size 12, then open the product page and note the name and price so I have a fallback main dress candidate. After that, on JJ’s House, browse cocktail dresses and find one deep V-neck option that looks like a dressier comparison point, and keep that product page open too so I can compare the styling. Once you’ve seen those dress options, decide which dress feels like the best value based on price and what’s actually available, then go to Old Navy and pick one comfortable-looking, affordable women’s jogger to round out the shortlist as a casual extra, making sure you open the actual product page and capture the name and price. Then check Tecovas for one men’s cowboy boot made of real leather, open the product page, and list the design or color options shown there so I can see how many choices there are. Finally, go to ALS and look up the Nike Phantom 6 Club FG/MG low-top men’s soccer cleat, tell me the current price, and say clearly whether it stays under $60 so I can judge whether this whole shortlist still feels budget-friendly. Please leave the key product tabs open for the dress comparison and give me a final shortlist with the item names, prices, the Tecovas options, and a quick note on which dress you’d personally pick as the best value.",

Finally, go to Citation Machine and confirm there’s a citation generator there that supports both APA and Harvard styles, because I want one place to cite the worksheet, the math site, and the video; if you can, navigate to where those style options are visible and leave that page open as proof. At the end, give me a short organized resource list with links for the worksheet, the math starting page, the video, and the citation generator site.",

Could you start on Hobbycraft and find three low-mess Christmas craft activities that feel toddler-friendly, then open the actual project pages in separate tabs so I can compare the photos and note the materials each one needs? After that, use Google to find three more at-home Christmas activity ideas for a toddler that are clearly different from the Hobbycraft ones, because I want a fuller mix of options beyond simple repeats, and open at least one of those source pages so I can see it’s a real activity page. Once you’ve got the toddler plan sorted, switch over to Scratch Magazine and look for Grinch Christmas nail inspiration, then find one Grinch tutorial page I could realistically follow and leave that tutorial page open so I can check the design details myself. From there, go to Amazon and find at least three Grinch-themed nail art ideas or products that use different materials, like stickers or decals, gel polish, brushes, glitter, rhinestones, stamping plates, or similar, and make sure they actually fit the style or techniques shown on the Scratch tutorial. Please open the most promising Amazon product pages in their own tabs so I can compare them visually, and then give me a clear summary with the toddler activity options, the Scratch tutorial, and the three nail product ideas with links plus a quick note on how each one matches the Grinch look.",

Please start on U.S. News and use its law school rankings to pull the top 20 U.S. law schools, including each school’s city and state, so I have a clean shortlist to work from. Then, for each of those 20 schools, go to the school’s official law school website and open the JD admissions page in its own tab so I can visually compare the official pages later. On each admissions page, verify the current JD application deadline, whether they accept the LSAT, GRE, or both for JD applicants, and the application fee if it’s listed on the admissions or application requirements pages. After that, stay on the official school sites and look for at least one real funding opportunity per school when possible—things like merit scholarships, named scholar programs, public interest fellowships, or other law student funding—so that we end up with at least 20 official funding opportunities total across the 20 schools. When you find one, open the actual program page in a new tab and verify the eligibility requirements and the funding amount or benefit if the school gives one, because I want this based only on official pages I could click through myself. Once you’ve gathered everything, create a CryptPad Sheets spreadsheet titled Top Law Schools and Fellowships and enter one row for each school with the school name, location, application deadline, LSAT/GRE policy, application fee, and the official admissions link. Then add the funding opportunities in the same sheet or a clearly labeled second tab with the school name, scholarship or fellowship name, eligibility criteria, funding amount or benefit if listed, and the official program link.

For each promising professor, open the actual faculty profile or personal website in a new tab, and if they have a lab page open that too in another tab so I can visually inspect the pages later; I especially want you to look for signs like \"accepting PhD students,\" \"recruiting,\" application guidance for prospective students, active lab rosters, recent projects, or anything else that suggests they are actively supervising graduate students right now. Please record at least 20 professors across the top schools, but try to spread them across the list instead of clustering everything at just MIT, Stanford, Berkeley, and CMU, because I want a broad application strategy. As you go, keep the relevant professor and lab tabs open so I can review the evidence on screen, and if a professor does not explicitly say they are accepting students, note that clearly rather than guessing. Once the sheet looks complete, do a consistency pass to make sure the links work, the research areas match what is actually on the pages, and the accepting-students status is backed by visible evidence. Then add a short summary section in the sheet or a companion doc explaining which universities seem to have the biggest clusters of ML/AI faculty who appear open to advising new PhD students, so I can see where my odds and fit might be strongest.",

After that, search for car rental options at whichever airport makes more sense for the dates I'd need, and open at least one rental listing so I can see the vehicle type and daily rate.

Please start on MovingAPT.com and get me a long-distance estimate for a 1-bedroom apartment move from Pittsburgh, PA to San Francisco, CA, and keep the quote page or results open so I can look at what assumptions they used. Then do the same on International Van Lines for the same 1-bedroom move, because I want at least two full-service mover quotes to compare. After that, check PODS for a container option that would make sense for a 1-bedroom apartment on that same route, and then check U-Pack for the equivalent portable moving setup, making note of whether they’re pricing by container count, trailer space, delivery, or monthly rental. Once those are open, go to U-Haul and price out a one-way 15-foot truck from Pittsburgh to San Francisco, then on U-Haul’s site find the MPG or fuel economy info for that truck so we can estimate the real driving cost. Use Google Maps to pull up the driving route from Pittsburgh, PA to San Francisco, CA and record the mileage, and leave the map visible so I can sanity-check the route distance on screen. I also have State Farm renters insurance, so please look on State Farm’s site to see whether my belongings are covered while they’re in transit during a move or whether I’d probably need separate moving coverage or valuation. After that, check Trustpilot for MovingAPT, International Van Lines, PODS, U-Pack, and U-Haul, and open each company’s Trustpilot page in its own tab so I can visually compare the ratings and review counts. In the end, pull everything together into one comparison with the estimated total cost for each option, and for U-Haul please calculate the truck rental plus estimated fuel cost using the route mileage and the truck MPG, so I can see which option is cheapest and which seems safest.",

As you find anything that looks promising, open the actual official program page in its own tab and read it closely to verify those details, then open the official application or admissions page in another tab so I can see what applying would really involve. While you do that, create a spreadsheet called Pre-College Summer Programs in CryptPad Sheets and log every verified match with the university name, program name, location, length, whether it offers college credit or clearly college-level classes, the application deadline if it’s listed, the program-page link, and the application-page link.

After you’ve covered the Northeast, expand to a few other strong top-30 schools like Stanford, UChicago, Duke, Northwestern, Rice, Vanderbilt, WashU, UCLA, or Berkeley and apply the same standards. Please keep the matching program tabs and their application tabs open so I can visually inspect them myself afterward, and when you’re done give me a short summary that highlights the strongest Northeast fits first, with a few especially good non-Northeast options as backups.",

Please research easyJet complaints across public sources and build me a practical picture of what goes wrong most often and whether the airline’s published support and passenger-rights information actually covers those situations. Start by finding at least 18 distinct recent customer complaints from at least 4 different public sources, and group them into the biggest recurring themes like delays, cancellations, refunds, baggage, check-in, customer service, or anything else that clearly shows up. For each complaint you keep, note the topic, where it was posted, and a short plain-English summary of what happened. Then open easyJet’s own public help pages for the main complaint themes you found and compare what the airline says customers should do in those situations, including contact/help options and any refund, disruption, or baggage guidance that is publicly available. After that, check at least 3 independent public passenger-rights or consumer-guidance sources so I can see what travelers may actually be entitled to when flights are disrupted or problems occur. Keep the most useful evidence tabs open from both the complaint sources and the official/help pages so I can inspect them myself. Finally, give me one organized decision memo that covers: the top recurring complaint themes, how often each theme appeared in your 18-plus examples, what easyJet’s own pages say about those issues, where outside guidance seems to support or contradict the practical customer experience, and your bottom-line judgment on whether easyJet looks acceptable for a budget-conscious traveler, risky unless the fare savings are large, or worth avoiding for certain trip types.",

Please build me a realistic backpacker budget across exactly 8 major tourist destinations in China, and make it structured enough that I could use it to decide whether the trip is affordable and which route makes the most sense. Start by identifying 8 widely recognized stops that would make a coherent backpacking route for a first-time visitor, then compare each one using public pages for hostels or budget hotels, food options, and major paid activities or sights. For every destination, record a typical nightly budget stay price, a low-cost daily food estimate, and 2 to 3 representative activity costs, using 'not shown' if a field truly is not available. Then figure out the most practical budget-minded way to travel between each stop, with an estimated fare and rough travel time, comparing trains, buses, or flights when that actually matters. Please open and keep useful evidence tabs along the way, including a few lodging pages with photos, a few attraction or ticket pages, and map pages for representative cities so I can visually sanity-check the route. Put the final result into one organized planning document that lists all 8 destinations in route order, the per-day and per-stop cost assumptions, the intercity transport costs, and a realistic total for the full trip.

Next, check public safety and ownership-risk signals for the Kia K5 GT using sources like IIHS, NHTSA, recall pages, and owner-review or reliability pages if available, and note anything that looks like a meaningful concern or a reassuring sign; if a field is not shown, say not shown. Finally, give me a ranked recommendation with exactly 3 outcomes: best value pick, best performance-leaning pick, and best all-around daily-driver pick.

Start by finding 10 to 12 plausible wired earbud or IEM models that are still easy to buy from major public pages, with Amazon included whenever possible, and keep the scope focused on everyday-use wired options rather than studio gear. For each candidate, compare the things that usually matter for longevity: cable thickness or strain relief, whether the cable is detachable, connector type, inline mic if shown, warranty length if publicly stated, price, and any obvious build-quality cues from the photos and product details. Then cross-check those candidates with at least one credible review or detailed discussion source per model so we are not relying on retailer marketing alone, and pay special attention to recurring failure complaints like one side dying, weak plugs, or bad strain relief. After that, narrow the list to exactly 4 finalists that look strongest on durability-for-price, and for each finalist keep open the Amazon listing plus one supporting non-Amazon evidence page. Among those 4, tell me which one is the best overall pick, which one is the best budget pick, which one is best if I want a detachable cable for easier long-term replacement, and which one should be avoided even if the sound looks attractive because the durability evidence is weak. Put the final comparison into one short decision memo organized by candidate, with prices marked as shown or not shown, and leave the most useful tabs open so I can review the finalists and buy from Amazon afterward.

+  install/upgrade it. Never pass \`--local\`, \`--remote\`, or \`--session\` —
+  the harness's wrapper appends the correct environment and session flags to
+  every command automatically.
+- Run exactly one \`browse ...\` command per Bash tool call. Shell operators
+  (\`|\`, \`&&\`, \`;\`, backticks, \`$()\`, and redirection) are rejected by the
+  harness, so chained or piped commands will fail.
+- Ignore the sections below about installing \`browse\`, Browse.sh skill
+  discovery/installation (\`browse skills ...\`), Browserbase cloud/session/
+  context/extension management (\`browse cloud ...\`), Functions
+  (\`browse functions ...\`), and Templates (\`browse templates ...\`) — all out
+  of scope during evals. Do not run those commands even though they are
+  documented below.
+- Do not edit repository files. Do not use network or web tools other than
+  \`browse\`.
+- When finished, report the result in the exact \`EVAL_RESULT\` format
+  requested by the harness prompt.

+ * claudeCodeAdapter — converts a Claude Code SDK run into a `Trajectory` the
+ * verifier can consume.
+ *
+ * Input shape: the SDK emits a stream of `ClaudeSdkMessage` objects of
+ * different `type`s — assistant (model output, may contain tool_use blocks),
+ * user (tool_result blocks for prior tool_use calls), and result (final
+ * outcome with cost/usage/turn counts). We accumulate the stream upstream in
+ * `runClaudeCodeAgent` and hand the full list here.
+ *
+ * Mapping:
+ *   - Each `tool_use` block in an assistant message becomes one normalized
+ *     tool call, paired with its matching `tool_result` from a subsequent
+ *     user message (by `tool_use_id`).
+ *   - Assistant `text` blocks that precede a tool_use are folded into that
+ *     tool call's `reasoning`. Trailing text after the last tool call (and
+ *     the final result message's `result` string when present) becomes the
+ *     `finalAnswer`.
+ *   - The result message's usage carries forward as the trajectory usage.
+ *
+ * Failure modes:
+ *   - max_turns / sdk_error → status = "error", but we still emit whatever
+ *     steps we have. The verifier flags evidence_insufficient on criteria it
+ *     can't ground.

+/**
+ * codexAdapter — converts a Codex SDK run into a `Trajectory` the verifier
+ * can consume.
+ *
+ * Input shape: codex emits `ThreadEvent`s — `item.completed` carrying a
+ * `ThreadItem` (command_execution, file_change, mcp_tool_call, agent_message,
+ * reasoning, web_search, todo_list, error), plus `turn.completed` for usage.
+ * We accumulate the full event list upstream in `runCodexAgent` and hand it
+ * here.
+ *
+ * Mapping:
+ *   - command_execution items → tool call named `bash` (or the command's
+ *     leading token), args = { command }, result = aggregated_output,
+ *     ok = exit_code === 0.
+ *   - mcp_tool_call items → tool call named `${server}.${tool}`, args =
+ *     arguments, result = structured_content (json modality) when present,
+ *     else flattened content text. ok = status !== "failed".
+ *   - reasoning items between item.completed events → folded into the next
+ *     tool call's reasoning string.
+ *   - agent_message items → the final answer (last wins).
+ *   - error items → captured as a failed tool call so the verifier sees the
+ *     pattern (a no-op `error` action with the message in toolOutput.error).
+ *   - file_change items → captured as a tool call named `file_change` with the
+ *     change set in args (rare in browser eval contexts).
+ *   - web_search items → captured as a tool call named `web_search` with the
+ *     query in args.
+ *   - todo_list items → not surfaced as tool calls (they aren't actions).

+ * - Supports multiple models, defaulting to certain sets of models depending on the category.
+ * - Runs each selected task against each selected model in parallel, collecting results.

+/**
+ * Build packages/evals/datasets/odysseysbench/OdysseysBench_data.jsonl from the
+ * published OdysseysBench task set.
+ *
+ * OdysseysBench (https://odysseysbench.com) is a 200-task web-agent benchmark
+ * (45 easy / 46 medium / 109 hard). Every task ships a weighted rubric whose
+ * weights sum to 1.0. This script converts each task's `rubrics` map into the
+ * verifier's `precomputed_rubric` shape ({ items: [{ criterion, description,
+ * max_points }] }) so the suite can hand it straight to V3Evaluator.verify()
+ * without generating a rubric.
+ *
+ * Source of truth is the committed snapshot at
+ *   packages/evals/datasets/odysseysbench/source/tasks.json
+ * (mirrored from https://odysseysbench.com/assets/data/tasks.json). Re-fetch
+ * with `--fetch` to refresh that snapshot before rebuilding.
+ *
+ * Run after pulling the branch (or whenever the source snapshot changes):
+ *   pnpm tsx packages/evals/scripts/build-odysseysbench-dataset.ts
+ *
+ * Idempotent — regenerates the JSONL deterministically from the snapshot.

+ * Sections:

+ *   2. Config     — evals.config.json path, defaults.env/trials/concurrency, core.*
+ *   3. Discovery  — total tasks + core/bench split
+ *   4. API keys   — full matrix from snapshotEnv() with source provenance
+ *   5. Verdict    — ok | warn | fail; exit code 0 | 0 | 1 (sans --json)
+ *
+ * Flags:
+ *   --json     machine-readable output, always exit 0
+ *   --help/-h  prints printDoctorHelp()
+ *   --probe    HIDDEN. Issues a tiny no-op LLM call to verify the OpenAI key
+ *              actually works. Used in CI; not advertised in --help.

+    Stagehand SDK for AI browser automation [ALPHA]. This API allows clients to
+
+    execute browser automation tasks remotely on the Browserbase cloud.
+
+    All endpoints except /sessions/start require an active session ID.
+

+ * - postject installed; tar available for non-Windows downloads.
+ *
+ * Args: --mode=esm|cjs --target-platform=<platform> --target-arch=<arch> --binary-name=<name>
+ * Env: SEA_BUILD_MODE, SEA_TARGET_PLATFORM, SEA_TARGET_ARCH, SEA_BINARY_NAME,
+ *      SEA_INCLUDE_SOURCEMAPS.
+ * Example: pnpm run build:sea:cjs -- --target-platform=linux --target-arch=arm64
